How to Fix a Black Screen on Windows 11

A black screen issue on Windows 11 can be frustrating, but there are several steps you can take to diagnose and fix it, whether it occurs before or after logging in. Here’s a step-by-step guide:

Before Logging In (Boot-up Black Screen):

1. Restart Your Computer: Sometimes, the issue can be temporary. Restart your computer and see if the problem issues.
2. Check Display Connections: Ensure that all cables connecting your monitor to your computer are securely plugged in. 
3. Try Safe Mode: To do this, restart your computer and keep pressing the F8 or Shift + F8 key during boot-up until the Advanced Startup Options menu appears. Then, select Safe Mode.
4. Check Graphics Drivers: Outdated or corrupted graphics drivers can cause black screen issues. To update your graphics drivers, right-click the Start button, select “Device Manager,” expand “Display adapters,” right-click your graphics card, and choose “Update driver.” Follow the on-screen instructions.
5. Check for Windows Updates: Ensure your Windows 11 is up to date by going to “Settings” > “Windows Update” and clicking “Check for updates.” Install any pending updates.
6. System Restore: If the issue started recently, you can try performing a System Restore to a point when your computer was working fine. Search for “Create a restore point” in the Start menu, then click the “System Restore” button.
7. Check for Malware: Malware infections can cause black screen problems. 

After Logging In (Desktop Turns Black):

1. Check for Malware: As mentioned earlier, malware can cause black screen issues. Run a full system scan using your antivirus or anti-malware software.
2. Update Graphics Drivers: Update your graphics drivers as mentioned in the previous section.
3. Check for Software Conflicts: Recently installed software or updates may be causing conflicts. Uninstall recently installed programs or updates to see if that resolves the issue.
4. Check for Corrupted User Profile: Sometimes, a corrupted user profile can cause black screen problems. Create a new user account and see if the issue persists when logging in with the new account.
5. Run System File Checker (SFC): SFC can scan and repair corrupted system files. Let it complete the scan and repair process.
6. Use Windows Troubleshooter: Go to “Settings” > “System” > “Troubleshoot” and run the Windows Troubleshooter for display or hardware and devices.
7. Check Startup Programs: Some third-party applications can cause issues during startup. Open “Task Manager” (Ctrl + Shift + Esc), go to the “Startup” tab, and disable unnecessary startup programs.
8. Perform a System Reset: If none of the above steps work, you can try performing a system reset. Go to “Settings” > “System” > “Recovery” and click “Reset this PC.” Choose the option to keep your files or remove everything, depending on your preference.

If you’re still experiencing the black screen issue after trying these steps, it may be worth consulting with a professional technician or contacting Microsoft support for further assistance, as there could be more complex underlying hardware or software issues.
