When your Windows computer is misbehaving—crashing, freezing, or simply refusing to start normally—Safe Mode is your go-to diagnostic tool. Safe Mode is a special startup environment that loads only the bare minimum of services, drivers, and programs required for Windows to run. This helps in isolating issues caused by third-party software, faulty drivers, or malware that might be preventing your system from operating correctly in standard mode. Knowing how to access Safe Mode is a crucial skill for any Windows user troubleshooting their PC.

Understanding Safe Mode

Safe Mode significantly simplifies the Windows environment by:

• Loading only essential drivers: This means your graphics card might run at a lower resolution, and some peripherals might not function.
• Disabling non-essential services: Background applications and services that aren’t critical for basic operation are turned off.
• Not running startup programs: No third-party applications will launch automatically.

This “clean” environment allows you to:

• Uninstall problematic software: Remove applications that are causing crashes or conflicts.
• Update or roll back drivers: Fix issues caused by faulty or outdated drivers.
• Run antivirus scans: Scan for and remove malware that might be difficult to detect in normal mode.
• Perform System Restore: Revert your system to a previous working state.

There are several ways to enter Safe Mode, depending on whether your Windows computer can boot normally or not.

Method 1: Booting into Safe Mode via Settings (For Bootable PCs)

This is the most common and straightforward method if your Windows PC can still boot into the desktop.

1. Open Settings:
   • Click the Start button (the Windows icon in the bottom-left corner of your screen).
   • Click on the Gear icon to open Settings, or type “Settings” into the search bar and press Enter.
2. Navigate to Recovery Options:
   • In the Settings window, click on “Update & Security” (for Windows 10) or “System” > “Recovery” (for Windows 11).
   • In the left-hand menu (Windows 10) or under “Recovery options” (Windows 11), click on “Recovery.”
3. Access Advanced Startup:
   • Under the “Advanced startup” section, click the “Restart now” button.
   • Windows will warn you that it’s about to restart. Click “Restart now” again to confirm.
4. Choose Safe Mode Option:
   • Your PC will restart and boot into the Windows Recovery Environment (WinRE), which provides a blue screen with several options.
   • Click on “Troubleshoot.”
   • Click on “Advanced options.”
   • Click on “Startup Settings.”
   • Click the “Restart” button.
5. Select Safe Mode:
   • After another restart, you’ll see a list of startup options.
   • Press 4 or F4 on your keyboard to enable Safe Mode.
   • Press 5 or F5 for Safe Mode with Networking (if you need internet access for troubleshooting, e.g., downloading drivers).
   • Press 6 or F6 for Safe Mode with Command Prompt (for advanced users who prefer command-line tools).

Your computer will then boot into Safe Mode. You’ll typically see “Safe Mode” written in the corners of your screen.

Method 2: Booting into Safe Mode from the Sign-in Screen (For PCs that reach Login)

If your PC boots to the login screen but goes no further, you can use this method.

1. Access Advanced Startup:
   • On the Windows sign-in screen, click the Power icon in the bottom-right corner.
   • Hold down the Shift key on your keyboard while you click “Restart.”
   • Keep holding Shift until the “Choose an option” (blue screen) appears.
2. Choose Safe Mode Option:
   • Follow steps 4 and 5 from Method 1:
     • Click “Troubleshoot.”
     • Click “Advanced options.”
     • Click “Startup Settings.”
     • Click “Restart.”
     • Press 4 or F4 for Safe Mode, or 5 or F5 for Safe Mode with Networking.

Method 3: Force Windows to Enter Safe Mode (When PC Won’t Boot Normally)

If your Windows PC fails to start normally multiple times, it will usually automatically enter the Windows Recovery Environment (WinRE). You can sometimes force this behavior.

1. Interrupt the Boot Process:
   • Turn on your computer.
   • As soon as you see the Windows logo (indicating Windows is trying to start), immediately press and hold the power button for 5-10 seconds to force a shutdown.
   • Repeat this process two more times.
   • On the third or fourth startup attempt, Windows should automatically enter the “Automatic Repair” screen.
2. Access Advanced Options:
   • On the “Automatic Repair” screen, click “Advanced options.”
3. Choose Safe Mode Option:
   • Follow steps 4 and 5 from Method 1:
     • Click “Troubleshoot.”
     • Click “Advanced options.”
     • Click “Startup Settings.”
     • Click “Restart.”
     • Press 4 or F4 for Safe Mode, or 5 or F5 for Safe Mode with Networking.

This method is particularly useful when you can’t even get to the desktop or the sign-in screen.

Method 4: Using a Windows Installation Media (For Completely Unbootable PCs)

If none of the above methods work, and your PC is completely unbootable (e.g., black screen on startup), you’ll need a Windows 10 or 11 installation USB drive or DVD. You can create this on another working computer.

1. Boot from Installation Media:
   • Insert your Windows installation USB or DVD into the problematic PC.
   • Restart your computer and repeatedly press the boot menu key (commonly F2, F10, F12, Del, or Esc – check your PC’s manufacturer for the exact key) to open the boot menu.
   • Select your USB drive or DVD as the boot device.
2. Access Repair Options:
   • On the Windows Setup screen, select your language and other preferences, then click “Next.”
   • Instead of clicking “Install now,” click “Repair your computer” in the bottom-left corner.
3. Choose Safe Mode Option:
   • This will take you to the same Windows Recovery Environment (WinRE) as in the previous methods.
   • Click “Troubleshoot.”
   • Click “Advanced options.”
   • Click “Startup Settings.” (If “Startup Settings” is not available directly, you may need to go to “Command Prompt” and then use the bcdedit commands, which is more advanced.)
   • Click “Restart.”
   • Press 4 or F4 for Safe Mode, or 5 or F5 for Safe Mode with Networking.

Exiting Safe Mode

To exit Safe Mode and boot back into normal Windows:

1. Simply Restart Your Computer:
   • Go to the Start button.
   • Click the Power icon.
   • Select “Restart.”
   • Windows should automatically boot into normal mode.
2. Check System Configuration (msconfig) if Stuck:
   • In rare cases, if your PC repeatedly boots into Safe Mode, it might be due to a setting in System Configuration.
   • Type “msconfig” into the Windows search bar and press Enter.
   • Go to the “Boot” tab.
   • Make sure the “Safe boot” checkbox is unchecked.
   • Click “Apply” and “OK.”
   • Restart your computer.

What to Do in Safe Mode

Once in Safe Mode, you can perform various troubleshooting tasks:

• Uninstall recent software: Go to Settings > Apps > Apps & features and remove any recently installed programs that might be causing issues.
• Update or Roll Back Drivers: Open Device Manager (right-click Start button > Device Manager) to update or roll back drivers for problematic hardware.
• Run System Restore: Use a previously created restore point to revert your system (type “Create a restore point” in search).
• Run a full antivirus scan: Use your installed antivirus software to scan for and remove malware.
• Check Disk for Errors: Open This PC, right-click on your C: drive, go to Properties > Tools > Check.
• Run System File Checker (SFC): Open Command Prompt as Administrator and type sfc /scannow to scan for and repair corrupted system files.

Safe Mode is an invaluable diagnostic environment that can help you resolve many Windows issues. By familiarizing yourself with these methods, you’ll be well-equipped to tackle common PC problems.

Having a second screen can dramatically boost your productivity, whether you’re juggling multiple applications, referencing documents, or just enjoying more screen real estate. While dedicated monitors are common, did you know you can often use an unused laptop as an external monitor for your primary Windows PC? This can be a cost-effective and portable solution for expanding your workspace.

Unlike connecting a dedicated monitor via HDMI or DisplayPort, connecting one laptop to another as a display often relies on wireless display technologies or third-party software. Laptops generally have video output ports (like HDMI Out), not video input ports. This guide will explore the most effective and common methods to turn your spare laptop into a valuable second screen.

Method 1: Using Windows’ “Project to this PC” Feature (Wireless – Windows 10 & 11)

Windows has a built-in feature called “Project to this PC” that leverages the Miracast standard. This allows one Windows PC to act as a wireless receiver for another, effectively turning it into a second screen. Both laptops need to support Miracast for this to work.

Part A: Configure the Laptop You Want to Use as the Second Screen (Receiver PC)

This is the laptop whose screen you want to project to.

1. Ensure “Wireless Display” Feature is Installed:
   • For Windows 11:
     • Go to Settings > System > Optional features.
     • Click “Add an optional feature” (or “View features” on newer builds).
     • Search for “Wireless Display.” Check the box next to it and click Next, then Install. This feature is not installed by default on some Windows 11 versions.
   • For Windows 10:
     • Go to Settings > Apps > Optional features.
     • Click “Add a feature”.
     • Find “Wireless Display” in the list. Select it and click Install.
2. Adjust “Projecting to this PC” Settings:
   • Go to Settings > System > Projecting to this PC.
   • Configure the following options:
     • “Some Windows and Android devices can project to this PC when you say it’s OK”:
       • Set to “Available everywhere” or “Available everywhere on secure networks.” “Available everywhere” is simpler for home use.
     • “Ask to project to this PC”:
       • Set to “First time only” (recommended for convenience) or “Every time.”
     • “Require PIN for pairing”:
       • Set to “Never” (for convenience if it’s your own devices) or “First time only.”
     • (Optional) “Discover this computer for projection only when this computer is plugged in”:
       • Toggle this Off if you want to project even when running on battery, or leave it on to save power.
3. Launch the “Wireless Display” App (or “Connect” App):
   • For Windows 11 (version 22H2 or later): Search for “Wireless Display” in the Start menu search bar and launch the app.
   • For Windows 10 or earlier Windows 11 versions: Search for “Connect app” in the Start menu search bar and launch it.
   • This app puts the receiving laptop into a discoverable state. Its screen will likely show a message like “[Laptop Name] is ready for you to connect wirelessly.”

Part B: Connect from Your Primary PC (Source PC)

This is the laptop or desktop you want to extend your display from.

1. Ensure both PCs are on the same Wi-Fi network. While Miracast can sometimes work peer-to-peer, being on the same network usually helps with discovery.
2. Open the “Cast” or “Connect” Menu:
   • Press Windows Key + K (the quickest shortcut).
   • Alternatively, open the Quick Settings / Action Center (click on the network/volume/battery icons in the taskbar corner) and click the “Cast” or “Connect” button.
3. Select Your Second Laptop:
   • Your primary PC will search for available wireless displays.
   • Select the name of your second laptop (the receiver PC) from the list.
4. Confirm Connection:
   • On the receiving laptop (the second screen), a prompt will appear asking if you want to allow the connection. Click “Yes” or “Allow.”
   • If you set a PIN, you’ll need to enter it on the primary PC.
5. Adjust Display Settings (on Primary PC):
   • Once connected, your primary PC’s desktop will extend to the second laptop screen.
   • Press Windows Key + P to open the “Project” menu.
   • Choose “Extend” to use the laptop as an additional monitor.
   • You can also go to Settings > System > Display on your primary PC to:
     • Rearrange the displays (drag and drop the numbered boxes to match your physical setup).
     • Adjust resolution and scale for the second laptop screen.
     • Select which display is the “main display.”

Method 2: Using Third-Party Software (Wireless/Wired)

Several third-party software solutions offer more robust features, better performance, or cross-platform compatibility, sometimes even allowing wired connections between laptops (though true wired direct video input is rare for laptops).

1. Spacedesk (Free for Personal Use):
   • Spacedesk is a popular free option that turns any Windows PC, Android tablet/phone, or even another iOS device into an extended display for your primary Windows computer. It works wirelessly over your Wi-Fi network or via USB tethering.
   • Installation:
     • On your Primary PC (Server): Download and install the spacedesk DRIVER software from spacedesk.net.
     • On your Second Laptop (Client/Viewer): Download and install the spacedesk VIEWER app from spacedesk.net (available for Windows, Android, iOS).
   • Connection:
     • Ensure both devices are on the same Wi-Fi network (or connected via USB tethering).
     • Launch the spacedesk DRIVER on the primary PC.
     • Launch the spacedesk VIEWER app on the second laptop.
     • The viewer app should automatically detect the primary PC. Tap on its name to connect.
   • Adjust Display Settings: Once connected, adjust your display settings on the primary PC (Windows Key + P or Settings > System > Display) as usual.
2. Duet Display (Paid):
   • Duet Display is a paid software known for its low latency and high performance, supporting both wired (USB) and wireless connections. While often marketed for iPad/iPhone, it also supports Windows to Windows.
   • Installation:
     • Purchase and install the Duet Display desktop client on your primary Windows PC from duetdisplay.com.
     • Purchase and install the Duet Display app on your second Windows laptop from the Microsoft Store.
   • Connection:
     • For wired: Connect the two laptops with a USB-A to USB-A cable (if compatible ports are available) or USB-C to USB-C cable.
     • For wireless: Ensure both are on the same Wi-Fi network.
     • Launch the Duet Display software on both machines and follow the on-screen prompts to connect.
   • Adjust Display Settings: Configure through Windows Display Settings on the primary PC.

Method 3: Wired Connection via Video Capture Card (Advanced/Specialized)

While most laptops lack a direct video input, it is technically possible to use a video capture card to route the video output from your primary PC into your second laptop. This is generally not recommended for typical second screen use due to cost, complexity, and latency, but it’s an option for specific scenarios like streaming/recording.

1. Acquire a Video Capture Card: You’ll need an external video capture card (USB 3.0 or Thunderbolt) that takes an HDMI input and outputs to a USB port.
2. Connect:
   • Connect an HDMI cable from the video output port of your primary PC (the one you want to extend from) to the HDMI input of the capture card.
   • Connect the capture card’s USB output to a USB port on your second laptop.
3. Use Capture Software:
   • On the second laptop, you’ll need software (often bundled with the capture card, or generic webcam software like OBS Studio) to view the video feed from the capture card.
   • You can then put this software in full-screen mode to use it as a display.

Managing Your New Dual-Monitor Setup

Once connected, whether wirelessly or via software, you can manage your new extended display from your primary Windows PC:

• Arrangement: Go to Settings > System > Display. Under “Rearrange your displays,” drag the numbered boxes to match how your laptops are physically positioned.
• Identification: Click “Identify” to see which number corresponds to which screen.
• Resolution and Scale: Adjust these settings for your second laptop to ensure text and images are clear and appropriately sized.
• Multiple Displays Dropdown (Windows Key + P):
  • “Duplicate these displays”: Shows the same content on both screens.
  • “Extend these displays”: Treats the second laptop as additional screen space. (This is usually what you want for a second screen setup).
  • “Show only on 1” or “Show only on 2”: Uses only one of the displays.

Using your laptop as a second screen can significantly enhance your computing experience, providing the extra workspace you need for improved productivity.

Frequently Asked Questions (FAQ)

Q1: Can I connect two laptops with an HDMI cable to use one as a second monitor?

Generally, no. Most laptops have HDMI output ports, meaning they are designed to send video from the laptop to an external monitor or TV, not to receive video into the laptop’s screen. Very few, highly specialized laptops have HDMI input ports. For most users, a direct wired connection between two laptops using only standard video cables is not possible for use as a second screen.

Q2: Is “Project to this PC” feature available on all Windows 10/11 laptops?

The “Project to this PC” feature is available on most Windows 10 and Windows 11 laptops, as long as they support Miracast. However, on some older or very budget-friendly laptops, the necessary hardware (Wi-Fi adapter with Miracast capabilities) might be missing, or the “Wireless Display” optional feature might need to be manually installed (as outlined in Method 1).

Q3: Why is my wireless second screen connection lagging or choppy?

Wireless connections, especially for video, can be susceptible to latency and choppiness. Common reasons include:

• Wi-Fi Network Congestion: Too many devices on your Wi-Fi network, or heavy network traffic.
• Distance/Obstructions: Being too far from your Wi-Fi router, or walls/objects blocking the signal.
• Interference: Other wireless devices operating on the same frequency.
• Hardware Limitations: Older Wi-Fi adapters or less powerful GPUs in either laptop can struggle with real-time video streaming.
• Software Issues: Outdated drivers on either laptop.
• Try: Moving closer to the router, disconnecting other devices, updating Wi-Fi drivers, and potentially using a third-party software solution like Spacedesk or Duet Display known for optimized performance.

Q4: Can I use an Android tablet or iPhone as a second screen for my Windows PC

Yes! While this article focuses on using another laptop, third-party software like Spacedesk and Duet Display are specifically designed to turn Android tablets, iPhones, or iPads into external monitors for your Windows PC, often via USB for low latency or wirelessly over Wi-Fi.

Q5: What are the advantages of using a laptop as a second screen over buying a dedicated monitor?

• Cost-Effective: If you have an unused laptop, it’s a free way to gain a second screen without buying new hardware.
• Portability: You can set up a dual-monitor workspace anywhere you have two laptops, making it ideal for travel or temporary setups.
• Utilizes Existing Hardware: Gives new life to an older laptop that might otherwise be collecting dust. However, dedicated monitors generally offer better performance (less latency, higher refresh rates), larger screen sizes, and more ergonomic setup options.

Display flickering in Windows can be incredibly disruptive, making your computer difficult to use and causing eye strain. This frustrating issue can stem from various sources, ranging from simple software glitches and outdated drivers to hardware malfunctions. The key to resolving it is a systematic approach to troubleshooting. This guide will walk you through how to fix display flickering in Windows, covering common causes and actionable solutions for both Windows 10 and Windows 11.

Understanding Why Your Display Might Be Flickering

Display flickering usually falls into one of two main categories:

1. Software-Related Issues:
   • Display Drivers: Outdated, corrupted, or incompatible graphics drivers are very common culprits.
   • Refresh Rate: Incorrect refresh rate settings for your monitor.
   • Problematic Apps: Certain applications, especially older ones, can conflict with the display driver or Windows, causing flickering.
   • Windows Bugs/Updates: Less common, but sometimes a recent Windows update can introduce display issues.
2. Hardware-Related Issues:
   • Loose/Damaged Cables: A loose or faulty video cable (HDMI, DisplayPort, DVI, VGA) can cause intermittent signal loss.
   • Faulty Monitor: The monitor itself might be failing.
   • Faulty Graphics Card: The graphics processing unit (GPU) in your PC might be malfunctioning.
   • Power Supply Issues: Insufficient or unstable power to the graphics card or monitor.

Step 1: Identify the Type of Flickering (Crucial Diagnosis)

Before you start, determine if the flickering affects only part of the screen, or if the entire screen flickers, including Task Manager. This helps narrow down the cause significantly.

1. Open Task Manager: Press Ctrl + Shift + Esc (or Ctrl + Alt + Delete, then Task Manager).
2. Observe Flickering:
   • If Task Manager also flickers: This usually indicates a display driver problem or a more severe hardware issue.
   • If Task Manager does NOT flicker, but everything else does: This strongly suggests a problematic application is causing the display issue.

Step 2: Troubleshoot Software-Related Flickering

Based on your Task Manager observation, start here if Task Manager doesn’t flicker or if you want to cover common software issues first.

Solution 1: Update or Reinstall Display Drivers (Most Common Fix)

Outdated or corrupted graphics drivers are a frequent cause of flickering.

1. Boot into Safe Mode (if flickering makes normal use difficult):
   • Windows 11: Go to Start > Settings > System > Recovery > Advanced startup > Restart now. Then Troubleshoot > Advanced options > Startup Settings > Restart, and select 4 or F4 for Safe Mode.
   • Windows 10: Click Start > Power, then hold Shift while clicking “Restart.” Then Troubleshoot > Advanced options > Startup Settings > Restart, and select 4 or F4 for Safe Mode.
2. Uninstall Current Display Drivers:
   • Right-click the Start button and select “Device Manager.”
   • Expand “Display adapters.”
   • Right-click on your graphics card (e.g., NVIDIA GeForce, AMD Radeon, Intel HD Graphics) and select “Uninstall device.”
   • If prompted, check the box that says “Attempt to remove the driver for this device” (or “Delete the driver software for this device”). Click “Uninstall.”
   • Do not restart yet.
3. Download Latest Drivers:
   • Go to the official website of your graphics card manufacturer (NVIDIA, AMD, Intel) or your laptop/PC manufacturer (Dell, HP, Lenovo, etc.).
   • Enter your exact graphics card model or PC model.
   • Download the latest stable display drivers compatible with your Windows version (10 or 11, 64-bit).
4. Install New Drivers:
   • After the download, restart your PC normally (exit Safe Mode).
   • Run the downloaded driver installer and follow the on-screen instructions.
   • Restart your PC again after installation.

Solution 2: Change Display Refresh Rate

An incorrect refresh rate can cause flickering or black screens.

1. Open Display Settings:
   • Windows 11: Right-click on an empty area of your desktop and select “Display settings.” Scroll down and click “Advanced display.”
   • Windows 10: Right-click on an empty area of your desktop and select “Display settings.” Scroll down and click “Advanced display settings” or “Display adapter properties” (then go to the “Monitor” tab).
2. Adjust Refresh Rate:
   • In the “Advanced display” settings (Windows 11) or “Monitor” tab (Windows 10), locate the “Refresh rate” dropdown menu.
   • Select the recommended refresh rate for your monitor (often 60 Hz, 120 Hz, or 144 Hz). If it’s already set to the highest, try a lower one (e.g., 60 Hz) to test.
   • Click “Keep changes” if the flickering stops.

Solution 3: Disable Problematic Applications

If Task Manager does not flicker, a specific app is likely causing the issue.

1. Check Task Manager (Again): While the flickering is happening, open Task Manager (Ctrl + Shift + Esc). If the Task Manager itself is stable and clear, but the background desktop flickers, an app is the culprit.
2. Identify Recent Apps: Think about any applications you installed or updated just before the flickering started.
3. Disable Startup Apps:
   • In Task Manager, go to the “Startup” tab.
   • Disable any non-essential apps, especially those with a “High” startup impact, by selecting them and clicking “Disable.”
   • Restart your PC and observe.
4. Uninstall Problematic Apps:
   • If disabling startup items doesn’t work, try uninstalling recently installed programs one by one.
   • Windows 11: Start > Settings > Apps > Installed apps.
   • Windows 10: Start > Settings > Apps > Apps & features.
   • After each uninstallation, restart your PC to see if the flickering stops.

Solution 4: Perform a Clean Boot

A clean boot starts Windows with a minimal set of drivers and startup programs, helping you isolate software conflicts.

1. Search for “System Configuration” in the Windows search bar and open it (msconfig.exe).
2. Go to the “Services” tab.
3. Check “Hide all Microsoft services” (crucial step).
4. Click “Disable all”.
5. Go to the “Startup” tab. Click “Open Task Manager” (if on Windows 10/11) and disable all non-Microsoft startup items there. Close Task Manager.
6. Click “Apply” and “OK” in System Configuration.
7. Restart your PC. If the flickering stops in a clean boot environment, a third-party app or service is the cause. You’ll need to re-enable them in small groups to pinpoint the culprit.

Step 3: Troubleshoot Hardware-Related Flickering

If Task Manager also flickers, or if software solutions don’t work, focus on hardware.

Solution 1: Check Display Cables

A loose or damaged video cable is a very common and easy-to-fix hardware issue.

1. Power Off Devices: Turn off your computer and monitor.
2. Reseat Cables:
   • Unplug the video cable (HDMI, DisplayPort, DVI, VGA) from both the back of your computer/graphics card and the back of your monitor.
   • Inspect the connectors for any bent pins or damage.
   • Firmly plug both ends of the cable back in, ensuring a secure connection.
3. Try a Different Cable: If reseating doesn’t work, swap out your current video cable for a different, known-good cable. A faulty cable can cause signal disruptions.
4. Check Power Cables: Ensure the power cables for both your PC and monitor are securely plugged into their respective outlets and devices.

Solution 2: Test with a Different Monitor

This helps determine if the issue is with your monitor or your computer’s graphics output.

1. Connect a Different Monitor: If you have access to another monitor, connect it to your PC using a different cable if possible.
2. Observe: If the flickering stops with the new monitor, your original monitor is likely faulty. If it continues, the problem is likely with your PC’s graphics card or internal components.

Solution 3: Test Graphics Card Output

If you have multiple video output ports on your graphics card (e.g., two HDMI ports, or an HDMI and a DisplayPort), try using a different port. This can sometimes bypass a faulty port.

Solution 4: Check for Overheating (Desktop PCs)

Overheating graphics cards can cause display issues.

1. Clean Dust: Open your desktop PC case and carefully clean any dust buildup from your graphics card fans and heatsinks using compressed air.
2. Monitor Temperatures: Use a monitoring tool (like HWMonitor or MSI Afterburner) to check your GPU temperatures, especially under load. If they are consistently very high, overheating could be a factor.

Solution 5: Seek Professional Help

If you’ve tried all the above steps and the flickering persists, it points to a more serious hardware issue.

• Faulty Graphics Card: The GPU itself might be failing.
• Motherboard Issue: Less common, but motherboard problems can affect display output.
• Laptop Display Panel: For laptops, the internal display panel or its connecting ribbon cable might be faulty.

What to do:

• Contact Manufacturer Support: If your PC or monitor is still under warranty, contact the manufacturer’s support.
• Visit a Repair Shop: Take your computer to a reputable computer repair shop for professional diagnosis and repair.

Display flickering in Windows can be a nuisance, but by systematically troubleshooting through software and hardware possibilities, you can usually pinpoint and fix the display flickering in Windows. Start with the simplest solutions, gather information from Task Manager, and work your way through to more complex diagnostics to restore a stable, clear display.

Windows updates are crucial for security and performance, but the mandatory automatic restarts that follow can be incredibly disruptive, leading to lost work or interrupted activities. Fortunately, Windows offers several ways to stop automatic restart after updates in Windows, allowing you to control when your system reboots and preventing unexpected downtime. This guide will walk you through the most effective methods available in Windows 10 and 11.

Understanding Windows Update Restarts

Windows updates often require a restart to fully apply changes to the operating system’s core components. By default, Windows tries to be smart about these restarts by using “Active Hours” or offering a restart notification. However, if a restart isn’t performed within a certain timeframe, Windows will eventually force it. Our goal is to prevent that forced restart and give you full control.

Important Note: While you can defer or prevent automatic restarts, it’s highly recommended to restart your system and apply updates regularly to ensure your system remains secure and stable. These methods are for managing the timing of the restart, not for avoiding it indefinitely.

1. Set Up Active Hours (The Easiest Method)

Active Hours tell Windows when you’re typically using your device, preventing restarts during those times. This is the simplest and most recommended approach for most users.

• Step 1: Open Windows Settings.
  • Click the Start button (Windows logo) in the bottom-left corner.
  • Click the Settings icon (gear symbol).
• Step 2: Navigate to Windows Update.
  • In the Settings window, click on “Windows Update” (on Windows 11) or “Update & Security” > “Windows Update” (on Windows 10).
• Step 3: Adjust Active Hours.
  • Windows 11: Click on “Advanced options.” Under “Restart options,” click on “Active hours.” You can choose to have Windows automatically adjust them based on your activity, or click “Manually” to set a custom start and end time.
  • Windows 10: Click on “Change active hours.“ You can choose to have Windows automatically adjust them, or click “Change” to set a custom start and end time.
• Step 4: Set Your Preferred Active Hours.
  • Define your active hours. For example, if you typically work from 9 AM to 5 PM, set your active hours from 9:00 AM to 5:00 PM. Windows will not restart during this window.
  • Click “Save” or “Confirm.”

2. Schedule a Restart or Pause Updates

If you have an update waiting for a restart, you can schedule it for a convenient time or temporarily pause updates.

• Step 1: Go to Windows Update Settings.
  • Settings > Windows Update (Windows 11) or Settings > Update & Security > Windows Update (Windows 10).
• Step 2: Schedule the Restart.
  • If a restart is pending, you’ll see a section like “Restart required”.
  • Click on “Schedule the restart” (Windows 11) or “Schedule the restart” / “Pick a restart time” (Windows 10).
  • Choose a specific date and time when you want the laptop to restart.
• Step 3: Pause Updates (Temporary Measure).
  • In the same Windows Update settings, you can find “Pause updates.”
  • Windows 11: Select a duration (e.g., “Pause for 1 week,” “Pause for 2 weeks”) from the dropdown. Updates will be paused until that date.
  • Windows 10: Click on “Pause updates for 7 days” repeatedly to extend the pause up to a maximum of 35 days.
  • Important: After the pause period ends, your laptop will download and install all pending updates, and a restart will eventually be required.

3. Adjust Restart Notifications (Windows 10/11)

Windows often gives you a notification that a restart is pending. You can configure how these notifications appear.

• Step 1: Access Advanced Options.
  • Go to Settings > Windows Update (Windows 11) or Settings > Update & Security > Windows Update (Windows 10).
  • Click on “Advanced options.”
• Step 2: Manage Restart Notifications.
  • Windows 11: Under “Restart options,” ensure “Get notifications when your PC requires a restart” is toggled On. This gives you a heads-up.
  • Windows 10: Under “Update settings,” look for the option “Show a notification when your PC requires a restart to finish updating” and ensure it’s toggled On. This provides a prompt.

4. Using Group Policy Editor (Windows Pro/Enterprise/Education Editions Only)

For users with Windows Pro, Enterprise, or Education editions, the Group Policy Editor offers more granular control over automatic restarts.

• Step 1: Open Group Policy Editor.
  • Press Windows key + R to open the Run dialog.
  • Type gpedit.msc and press Enter.
• Step 2: Navigate to Windows Update Settings.
  • In the Group Policy Editor, go to: Computer Configuration > Administrative Templates > Windows Components > Windows Update > Manage end-user experience
• Step 3: Configure “No auto-restart with logged on users for scheduled automatic updates installations.”
  • Double-click the policy setting: “No auto-restart with logged on users for scheduled automatic updates installations.”
  • Select “Enabled.”
  • Click “Apply” then “OK.”
  • What this does: If a user is logged in, Windows will not automatically restart the computer, even if updates are ready. It will wait for the user to manually restart.
• Step 4: Configure “Always automatically restart at the scheduled time” (Optional, for more control).
  • In the same Manage end-user experience folder, you might also find “Always automatically restart at the scheduled time.”
  • If you want to set a specific time for restarts without being forced immediately, you can double-click this, select “Enabled,” and choose a specific time. This overrides other automatic restart rules but gives you a set schedule.

5. Using Registry Editor (Advanced, Use with Caution!)

This method achieves similar results to Group Policy but requires directly editing the Windows Registry. Incorrect registry edits can cause system instability, so proceed with extreme caution and back up your registry first.

• Step 1: Open Registry Editor.
  • Press Windows key + R to open the Run dialog.
  • Type regedit and press Enter. Click “Yes” if prompted by User Account Control.
• Step 2: Navigate to the Windows Update Key.
  • Go to the following path (you can copy and paste it into the Registry Editor address bar): HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
  • If WindowsUpdate or AU folders don’t exist, you’ll need to create them. Right-click on the parent folder, select “New” > “Key,” and name it appropriately.
• Step 3: Create or Modify the NoAutoRebootWithLoggedOnUsers Value.
  • In the AU key, right-click in the empty space on the right pane.
  • Select “New” > “DWORD (32-bit) Value.”
  • Name the new value: NoAutoRebootWithLoggedOnUsers (case-sensitive).
  • Double-click the newly created NoAutoRebootWithLoggedOnUsers value.
  • Set its “Value data” to 1.
  • Click “OK.”
• Step 4: Restart Your Computer.
  • The change should take effect after a restart.

Summary of Methods and Recommendations:

• Most Users: Start with Active Hours and Scheduling Restarts. This provides excellent control without complex changes.
• Windows Pro/Enterprise/Education Users: Use Group Policy Editor for a more robust and persistent solution to prevent automatic restarts when a user is logged in.
• Advanced Users/Home Users on Windows Home: The Registry Editor method is an alternative to Group Policy, but use it with extreme care.

By applying one of these methods, you can successfully stop automatic restart after updates in Windows, ensuring your work remains uninterrupted and you choose the optimal time for system reboots.

Random Access Memory (RAM) is a crucial component of your computer, acting as its short-term memory. When your RAM experiences errors, it can lead to a range of frustrating issues, including system crashes (Blue Screens of Death – BSODs), unexpected shutdowns, freezing, and general instability. If you’re encountering these problems, learning how to run a memory diagnostic on your Windows computer is an essential troubleshooting step. Windows includes a built-in tool, the Windows Memory Diagnostic, which can help identify if your RAM is faulty.

Why Run a Memory Diagnostic?

Running a memory diagnostic can help you pinpoint the source of common PC problems:

• Diagnose Stability Issues: Frequent system crashes, freezes, or random reboots are strong indicators of potential RAM problems.
• Identify Blue Screen Errors: Many BSODs include error codes that specifically point to memory issues (e.g., MEMORY_MANAGEMENT).
• Troubleshoot Performance Degradation: If your computer feels sluggish even with sufficient resources, faulty RAM could be causing data corruption or hindering efficient data access.
• Verify New RAM: After upgrading or installing new RAM, running a diagnostic is a good practice to ensure the new modules are functioning correctly and are compatible with your system.
• Prevent Data Corruption: Undetected RAM errors can lead to corrupted files or even operating system corruption over time.

Understanding the Windows Memory Diagnostic Tool

The Windows Memory Diagnostic is a built-in utility that performs a series of comprehensive tests on your computer’s RAM. It’s designed to detect various types of memory errors that can cause system instability. The diagnostic runs before Windows fully loads, ensuring a thorough test without interference from other software.

Step-by-Step Guide: How to Run a Memory Diagnostic

Using the Windows Memory Diagnostic tool is straightforward. Here’s how to do it:

Step 1: Access the Windows Memory Diagnostic Tool

There are a couple of easy ways to launch the tool in Windows.

1. Using the Search Bar (Recommended):
   • Click on the Start button or the Search icon on your taskbar.
   • Type “Windows Memory Diagnostic” (or just “memory diagnostic”) into the search bar.
   • Select “Windows Memory Diagnostic” from the search results.
2. Using the Run Dialog:
   • Press Win + R to open the Run dialog box.
   • Type mdsched.exe and press Enter.

Step 2: Choose How to Run the Diagnostic

Once you launch the tool, you’ll be presented with two options:

1. “Restart now and check for problems (recommended)”: This is the most common and recommended option. Your computer will immediately restart, and the memory diagnostic will begin. Any unsaved work will be lost, so make sure to save everything before choosing this option.
2. “Check for problems the next time I start my computer”: This option is useful if you’re in the middle of important work. The diagnostic will run automatically the next time you restart your PC.

• Select “Restart now and check for problems (recommended)”.
  • Your computer will then prepare to restart.

Step 3: Let the Diagnostic Run

After your computer restarts, you will see a blue screen with the Windows Memory Diagnostic Tool interface.

1. Observe the Progress: The tool will automatically begin testing your RAM. You’ll see a “Status” area indicating the current test being performed, and a “Percentage complete” showing how much of the test has finished.
2. Test Passes: The standard test usually runs two passes. A pass is a complete cycle of all the defined memory tests.
3. No User Interaction Required: Do not interrupt the process. Let the diagnostic run its full course. This can take anywhere from 15 minutes to an hour or more, depending on the amount of RAM you have and the speed of your system.

Step 4: Interpret the Results

Once the Windows Memory Diagnostic finishes, your computer will automatically restart and boot back into Windows. The results of the diagnostic are displayed in a pop-up notification.

1. Check Notification: After logging back into Windows, keep an eye out for a notification bubble in the system tray (bottom-right corner near the clock). It will typically say something like:
   • “No memory errors were detected.” (Good news!)
   • “Your computer has a memory problem.” (Indicates errors were found.)
   • “Memory problems were detected. Contact your computer manufacturer for assistance.” (Another indication of errors.)
2. If No Notification Appears (Common): Sometimes, the notification doesn’t pop up automatically. You can manually check the Event Viewer to see the diagnostic results.
   • Press Win + X and select “Event Viewer” from the menu.
   • In Event Viewer, expand “Windows Logs” > “System.”
   • In the System log, click on “Find…” (or go to “Action” menu > “Find…”).
   • Type “MemoryDiagnostic” (or “MemoryDiagnostics-Results”) in the Find dialog box and click “Find Next.”
   • Look for an event with “Source” as “MemoryDiagnostics-Results.” Double-click on it to view the details. The “General” tab will state whether any errors were detected.

What to Do If Memory Errors Are Detected

If the Windows Memory Diagnostic tool reports errors, it’s a strong indication that one or more of your RAM modules are faulty. Here’s how to proceed:

1. Identify Faulty Stick (If Multiple Modules):
   • If you have multiple RAM sticks installed, the best way to isolate the faulty one is through a process of elimination.
   • Power down your computer completely and unplug it.
   • Open your PC case (for desktops) or access your laptop’s RAM slots.
   • Remove all but one RAM stick.
   • Run the Windows Memory Diagnostic again.
   • Repeat this process for each RAM stick individually. This will help you identify which specific stick (or sticks) is causing the errors.
   • Ensure proper anti-static precautions (touching metal, anti-static wrist strap) when handling RAM.
2. Reseat RAM Modules: Sometimes, a RAM stick might just be loosely seated. Before assuming it’s faulty, try this:
   • Power down and unplug your PC.
   • Gently push out the clips at each end of the RAM stick.
   • Carefully remove the RAM stick.
   • Reinsert it firmly into the slot, ensuring the clips click securely into place on both ends.
   • Try booting and re-running the diagnostic.
3. Clean RAM Slots and Sticks: Dust or debris on the RAM contacts or inside the slots can cause issues.
   • Power down and unplug your PC.
   • Remove the RAM sticks.
   • Use compressed air to blow out any dust from the RAM slots on the motherboard.
   • Gently clean the gold contacts on the RAM sticks with a pencil eraser or a microfiber cloth lightly dampened with isopropyl alcohol (let it dry completely before reinserting).
4. Replace Faulty RAM: If you’ve identified a faulty RAM stick and reseating/cleaning didn’t help, the module needs to be replaced.
   • Ensure you purchase RAM that is compatible with your motherboard and existing RAM (matching type, speed, and ideally size and timings). Refer to your motherboard’s manual or use tools like CPU-Z to get precise details.
   • Install the new RAM and run the diagnostic again to confirm it’s working correctly.

When to Consider a More Advanced Diagnostic (MemTest86)

While the Windows Memory Diagnostic is good for basic checks, for highly persistent or intermittent RAM issues, a more thorough tool like MemTest86 is often recommended by IT professionals and hardware enthusiasts.

• MemTest86: This is a free, open-source memory testing program that runs from a bootable USB drive or CD. It performs more extensive and rigorous tests than the built-in Windows tool, often detecting subtle errors that the Windows diagnostic might miss.
• How to Use MemTest86:
  1. Download the MemTest86 image file (usually an ISO or USB installer) from its official website.
  2. Create a bootable USB drive using a tool like Rufus or the provided MemTest86 USB installer.
  3. Restart your computer and boot from the USB drive (you may need to change the boot order in BIOS/UEFI).
  4. Let MemTest86 run for several hours (ideally 4-8 passes) to thoroughly test your RAM.

Conclusion

Knowing how to run a memory diagnostic on your Windows computer is a crucial troubleshooting skill that can save you time and frustration. The built-in Windows Memory Diagnostic provides a quick and accessible way to check your RAM for errors. If issues are detected, a systematic approach of isolation, reseating, cleaning, and eventual replacement will help restore your system’s stability and performance. For persistent problems, consider the more robust MemTest86 for an in-depth analysis of your memory modules.

Even the most stable Windows operating system can encounter issues that prevent it from booting normally. A faulty driver, a corrupted system file, or a malicious software infection can render your PC unusable. This is where Advanced Startup Options (often referred to as the Windows Recovery Environment – WinRE) in Windows 11 become an invaluable troubleshooting tool. These options provide a powerful suite of utilities that allow you to diagnose and repair your system, restore it to an earlier state, or even reinstall Windows without losing your personal files.

The concept of a recovery environment has evolved significantly over Windows versions. Earlier iterations often relied on physical recovery CDs or cumbersome processes. With Windows 11, Microsoft has streamlined access to these crucial tools, making them more accessible directly from the operating system or even when Windows fails to start. Understanding how to access and utilize these options is a fundamental skill for any Windows user.

What are Advanced Startup Options?

Advanced Startup Options is a specialized environment that provides access to various troubleshooting and recovery tools outside of the normal Windows boot process. It’s designed to help you resolve problems when your PC isn’t starting correctly or when you need to perform system-level maintenance. These options are part of the Windows Recovery Environment (WinRE), a minimal operating system built into your Windows installation.

Key tools you’ll find within Advanced Startup Options include:

• System Restore: Revert your system to an earlier working state.
• Startup Repair: Automatically fix common boot problems.
• Command Prompt: Advanced troubleshooting via command-line interface.
• Uninstall Updates: Remove problematic Windows updates.
• Startup Settings: Change boot behavior, including Safe Mode.
• Reset this PC: Reinstall Windows while keeping or removing your personal files.

Methods to Access Advanced Startup Options

FAQ Section

Q1: What is the Windows Recovery Environment (WinRE)?

The Windows Recovery Environment (WinRE) is a minimal operating system that comes preloaded with Windows 11. It provides a set of tools and utilities (the Advanced Startup Options) to help diagnose, repair, and recover Windows when it encounters critical errors or fails to start correctly.

Q2: What is the difference between “Reset this PC” and “System Restore”?

“Reset this PC” essentially reinstalls Windows 11. You have the option to keep your personal files, but all installed applications (not pre-installed by the manufacturer) and most settings will be removed. “System Restore,” on the other hand, rolls back your system files, installed applications, and registry settings to a previous point in time, without affecting your personal documents. It’s less drastic than a full reset.

Q3: How do I boot into Safe Mode in Windows 11 using Advanced Startup Options?

To boot into Safe Mode from Advanced Startup Options, navigate to Troubleshoot > Advanced options > Startup Settings. Then, click Restart. After your PC restarts, you’ll see a list of numbered options. Press 4 for Enable Safe Mode, 5 for Enable Safe Mode with Networking, or 6 for Enable Safe Mode with Command Prompt.

While Advanced Startup Options provides powerful tools, it cannot fix all problems. Hardware failures (like a dying hard drive or RAM issues), severe malware infections that deeply corrupt the system, or corrupted BIOS/UEFI settings might be beyond the scope of these built-in tools. In such cases, professional repair or a clean Windows installation might be necessary.

Q5: What if I don’t have a Windows 11 installation USB drive?

If you don’t have a Windows 11 installation USB drive, you can create one using the Media Creation Tool from Microsoft’s official website on another working computer. This bootable media is crucial for accessing the Advanced Startup Options if your PC is severely corrupted and cannot even initiate automatic repair.

Imagine this: You install a new program, update a driver, or tweak a system setting, and suddenly your Windows 10 PC starts behaving erratically – it crashes, slows down, or an application stops working. This is a common scenario for many computer users. While regular backups of your personal files are crucial, they don’t help if the operating system itself becomes unstable. This is where System Restore Points come in.

A System Restore Point is essentially a snapshot of your Windows system files, installed applications, Windows Registry, and system settings at a specific moment in time. Think of it as a rewind button for your computer’s software configuration. If an issue arises after a change, you can “restore” your system to an earlier state where everything was working correctly, without affecting your personal documents, pictures, or other data.

The concept of system restoration has been a part of the Windows operating system since Windows ME, providing users with a safety net for software-related problems. In Windows 10, while it creates automatic restore points during significant system changes (like major Windows updates or some software installations), manually creating one before making risky changes is a proactive and highly recommended practice.

Why Create a Restore Point?

Creating a restore point acts as a safeguard. It’s particularly useful before:

• Installing new software or drivers that you’re unsure about.
• Making significant changes to system settings or the Windows Registry.
• Running system optimization tools or uninstalling multiple programs.
• Performing complex troubleshooting steps.

It’s your insurance policy against unforeseen software conflicts or corruption.

• Not a Backup Replacement: System Restore is not a replacement for a full file backup. It only affects system files, installed programs, and registry settings. Your personal documents, photos, videos, and other user data will remain untouched. Always back up your important personal files regularly to an external drive or cloud service.
• Disk Space Management: Monitor the disk space allocated for System Restore. If you allocate too little, older restore points will be automatically deleted sooner. If you have plenty of space, you can keep more restore points.
• Automatic Restore Points: Windows 10 automatically creates restore points before major updates, driver installations, and some software installations. However, these aren’t guaranteed, which is why manual creation is important.
• Troubleshooting Tool: Think of System Restore as a quick troubleshooting tool for software issues, not a comprehensive disaster recovery solution.
• Disable and Re-enable if Issues: Sometimes, if System Restore isn’t working correctly, disabling it, restarting your PC, and then re-enabling it can resolve underlying issues.

FAQ Section

Q1: What exactly does a System Restore Point save?

A System Restore Point saves a snapshot of your Windows system files, installed applications, the Windows Registry, and critical system settings. It does not save your personal files such as documents, photos, music, or videos.

Q2: Will using a restore point delete my personal files?

No, using a System Restore Point will not delete your personal files. It only affects system-level changes, installed programs, and drivers that were changed after the restore point was created. Any documents, pictures, or videos you created or saved will remain untouched.

Q3: How much disk space should I allocate for System Restore Points?

For most users, allocating 3-5% of your primary drive’s total capacity for System Restore Points is usually sufficient. This allows for a reasonable number of restore points to be saved. If you have a smaller drive or limited space, you might need to adjust this down, but be aware that older restore points will be deleted more quickly.

Q4: My “Create…” button is grayed out. What should I do?

If the “Create…” button is grayed out, it means System Protection is not enabled for your primary system drive (usually C:). You need to first select your C: drive in the System Protection tab, click the Configure… button, and then select “Turn on system protection” and set the disk space usage.

Q5: How often does Windows 10 create automatic restore points?

Windows 10 automatically creates restore points under certain conditions, such as before significant system updates (like feature updates), when some applications are installed, or when certain drivers are updated. However, these automatic points are not scheduled daily or weekly. For critical tasks, manually creating a restore point is always recommended.

What to Look for When Upgrading RAM

• RAM Type: Match the DDR generation (e.g., DDR4).
• Speed (MHz): Ideally match or compatible with current modules.
• Capacity: Add up total capacity within motherboard limits.
• Form Factor: Ensure it’s SODIMM (for laptops).
• ECC vs. Non-ECC: Most laptops use Non-ECC.

By systematically going through these steps, you can accurately determine if your laptop supports a RAM upgrade and confidently select the correct modules to boost its performance.

When your Windows PC flashes that all-too-familiar “No Internet” message—especially while using an Ethernet cable—it can feel unnecessarily frustrating. Ethernet is supposed to be the stable one, right? It’s often more reliable than Wi-Fi, so seeing it fail leaves you wondering where things went sideways.

The cause might be surprisingly simple, like a loose connection, or it might dig deeper—perhaps a misbehaving driver or some obscure network configuration issue. Either way, you don’t need to panic. This step-by-step guide will walk you through the most effective ways to troubleshoot and fix Ethernet-related “No Internet” errors on a Windows PC.

How to Fix “No Internet” in Windows When Using Ethernet

A “No Internet” message with an Ethernet setup usually signals that something along the chain—from your PC to your router/modem, and out to your ISP—is broken. Often, it’s something minor. So let’s start with the basics and work our way toward more advanced fixes.

Step 1: Begin with the Obvious (and Most Overlooked) Checks

Inspect the Ethernet Cable

It sounds obvious, but you’d be surprised how often the cable itself is the culprit.

• Make sure it’s snugly connected on both ends—PC and router.
• Look for LED lights near the Ethernet port. No lights? That’s usually a red flag.
• If you have another cable handy, give it a try. Sometimes cables go bad.
• Also, double-check you’re using an actual Ethernet cable (Cat5e or Cat6), not a lookalike phone cord.

Restart Your Modem and Router

Sometimes, your equipment just needs a fresh start.

1. Unplug both modem and router.
2. Wait about 30–60 seconds.
3. Plug in the modem first, let it stabilize.
4. Then plug in the router.
5. Restart your PC.

Check Indicator Lights

On both modem and router:

• A steady “Internet” or “WAN” light is a good sign.
• Blinking erratically, off, or red? You might be looking at an ISP issue. Consider calling them.

Try Another Device

Can other devices connect to the internet using the same router?

• If yes, the issue is likely your Windows PC.
• If no, the problem is more likely with your modem/router or the ISP.

Step 2: Check Windows Settings and Tools

Run the Network Troubleshooter

Sometimes, Windows can diagnose itself.

• Windows 11: Settings > Network & internet > Advanced network settings > Network troubleshooter.
• Windows 10: Settings > Network & Internet > Status > Network troubleshooter.

Look at Your Ethernet Adapter

• Right-click Start > Device Manager > Network adapters.
• Look for any warning signs (like a yellow exclamation point or red X).
• If it’s disabled (you’ll see a down arrow), right-click and choose “Enable.”

Update or Reinstall Drivers

• In Device Manager, right-click the Ethernet adapter.
• Try “Update driver” > “Search automatically.”
• If that fails, visit your PC/motherboard manufacturer’s site for the latest driver.
• As a last resort, uninstall the device and restart your PC. Windows should reinstall a default driver.

Reset Network Adapters

A full reset can often wipe out hidden issues.

• Windows 11: Settings > Network & internet > Advanced network settings > Network reset.
• Windows 10: Settings > Network & Internet > Status > Network reset.
• Click “Reset now” and reboot your PC.

Step 3: Dive Into Network Configuration

Refresh Your IP

Sometimes your PC clings to an expired IP address.

1. Open Command Prompt (Admin).
2. Type: ipconfig /release
3. Then: ipconfig /renew
4. To verify: ipconfig /all

Flush DNS Cache

A corrupt DNS cache can stall browsing.

1. In the same Command Prompt:
   • ipconfig /flushdns
   • netsh int ip reset
   • netsh winsock reset
2. Restart your PC.

Double-Check Proxy Settings

• Windows 11: Settings > Network & internet > Proxy.
• Windows 10: Settings > Network & Internet > Proxy.
• Ensure “Automatically detect settings” is ON.
• Make sure manual or script settings are OFF—unless you specifically use a proxy.

Disable Security Software Temporarily

Firewalls and antivirus programs sometimes block legit traffic.

• Try disabling Windows Firewall or third-party antivirus software briefly.
• If this restores your connection, look into creating an exception rather than leaving it off.

Step 4: Advanced Troubleshooting

Check for IP Conflicts

If two devices fight over the same IP, it can get messy.

• Log into your router (typically at 192.168.1.1 or 192.168.0.1).
• Look for duplicate IPs in the DHCP client list.
• Restart the affected devices or set a static IP.

Investigate VPN Software

Some VPNs can mess with network access even when they’re turned off.

• Try uninstalling it completely and see if that resolves things.

Scan for Malware

Malware can disrupt connections in all sorts of sneaky ways.

• Run a full system scan using Windows Defender or a trusted third-party antivirus.

Try a Clean Boot

To rule out software conflicts:

• Perform a clean boot (search Microsoft’s guide on how to do this).
• If the internet works, re-enable startup programs one by one to find the issue.

Reinstall Windows (Only If You Must)

If nothing else works:

• Backup your data.
• Perform a clean install of Windows. This is the nuclear option—but it can fix deeply-rooted issues.

Final Thoughts

Dealing with a “No Internet” message on an Ethernet connection might feel overwhelming at first, but it’s rarely unsolvable. By methodically checking each layer—from physical cables and router restarts to Windows settings and driver configurations—you can often get things back up and running without needing to call in a tech pro.
