How to Fix Flashing Screens on Windows 8.1: Effective Troubleshooting Steps

Experiencing a flashing screen on your Windows 8.1 computer can be frustrating and disruptive. This issue may occur due to various reasons, from software glitches to hardware problems. Understanding how to fix it is essential to get your system back to normal.

In this guide, we will walk you through simple and effective troubleshooting steps. Each step is explained clearly to help even beginners resolve the flashing screen problem.

By following these instructions carefully, you can save time and avoid unnecessary repairs. Let’s start with some quick checks before moving into detailed solutions.

Remember, patience is key when troubleshooting. Take your time and proceed step-by-step.

Quick Note: Prerequisites and Initial Checks

  • Save Your Work: Before starting any troubleshooting, save all important files to avoid data loss.
  • Check for External Factors: Sometimes, loose cables or faulty monitors cause screen flashing. Make sure your monitor cable is securely connected.
  • Restart Your PC: A simple restart can fix minor glitches causing the screen to flash.
  • Note When the Problem Occurs: Is the flashing constant, or does it happen only when opening specific apps? This info helps diagnose the issue.

Step 1: Update Your Display Drivers

The most common cause of screen flashing is outdated or corrupted display drivers. Drivers are software that help your computer communicate with hardware. Keeping them updated ensures smooth performance.

  1. Press Windows + X on your keyboard and select Device Manager from the menu.
  2. In the Device Manager window, expand the section labeled Display adapters.
  3. Right-click your display adapter (usually has “Intel”, “NVIDIA”, or “AMD” in the name) and choose Update driver.
  4. Select Search automatically for updated driver software and wait while Windows searches and installs any available updates.
  5. Once done, restart your computer to apply the changes.

If Windows cannot find an update, visit your display adapter manufacturer’s website for the latest driver and follow their instructions to install it manually.

Step 2: Check for Problematic Apps

Some apps or programs running in the background may cause screen flashing due to incompatibility or bugs.

  1. Press Ctrl + Shift + Esc to open the Task Manager.
  2. Look for apps that use high CPU, memory, or disk resources under the Processes tab.
  3. Try closing apps one by one by selecting them and clicking End task.
  4. Observe if the screen flashing stops after closing any particular app.

If you identify a problematic app, consider updating it, reinstalling it, or uninstalling it if the issue persists.

Step 3: Disable Automatic App Updates

In Windows 8.1, automatic app updates sometimes cause screen flashing, especially when an update conflicts with your display settings.

  1. Open the Windows Store app.
  2. Swipe from the right edge of the screen or move your mouse to the top-right corner to open the Charms Bar.
  3. Select Settings > App updates.
  4. Turn off the option called Automatically update my apps.
  5. Manually update apps at your convenience to avoid sudden disruptions.

Step 4: Adjust Screen Refresh Rate

The screen refresh rate controls how often your display updates per second. Incorrect settings can cause flickering or flashing.

  1. Right-click on the desktop and select Screen resolution.
  2. Click on Advanced settings.
  3. Navigate to the Monitor tab.
  4. Under Screen refresh rate, select a different value from the dropdown menu (try 60 Hz if it’s higher).
  5. Click Apply and then OK.
  6. Check if the flashing stops.

Step 5: Run System File Checker (SFC)

Corrupted system files can cause display problems. Windows has a built-in tool to scan and repair these files.

  1. Press Windows + X and select Command Prompt (Admin) or Windows PowerShell (Admin).
  2. Type the following command and press Enter:
sfc /scannow

This process may take some time. Once complete, it will display a message about whether corrupted files were found and repaired.

Restart your computer and see if the screen flashing issue is resolved.

Step 6: Boot into Safe Mode

Safe Mode starts Windows with a minimal set of drivers and apps. If the flashing stops in Safe Mode, it points to software or driver conflicts.

  1. Press Windows + R, type msconfig, and press Enter.
  2. Go to the Boot tab.
  3. Check the box for Safe boot and select Minimal.
  4. Click OK and restart your computer.
  5. If the screen does not flash in Safe Mode, uninstall any recently installed programs or drivers that may cause the problem.
  6. To exit Safe Mode, repeat the steps and uncheck Safe boot.

Step 7: Update Windows 8.1

Microsoft often releases updates that fix bugs and improve system stability. Keeping your Windows updated can resolve flashing screen issues caused by software bugs.

  1. Open Control Panel.
  2. Go to System and Security > Windows Update.
  3. Click Check for updates.
  4. Install all important updates and restart your PC.

Alternative and Advanced Methods

If the above steps do not fix the problem, consider the following options:

  • Rollback Display Driver: If the issue started after a recent driver update, try rolling back to the previous version in Device Manager.
  • Check for Malware: Use antivirus software to scan your system, as malware can cause erratic screen behavior.
  • Check Hardware: Test your monitor with another computer or try a different cable to rule out hardware issues.
  • Perform a System Restore: Restore your PC to a point before the problem began. Search for “System Restore” in the Start screen and follow the instructions.
