Black screens on Windows 11 are primarily caused by faulty, outdated, or corrupted graphics drivers, failed Windows updates, or issues with display connections. To quickly fix it press Windows + Ctrl + Shift + B to reset the graphics driver (the screen may flicker briefly), or press Ctrl + Alt + Delete to open the security screen and select Restart from the power icon if the system is frozen but responsive.
1. Check physical connections: Turn off the PC and ensure HDMI, DisplayPort, or VGA cables are securely connected, trying a different port or monitor if possible.
2. Boot into Safe Mode: Restart the computer, hold Shift while clicking Restart on the login screen, then navigate to Troubleshoot > Advanced options > Startup Settings and press 4 to enter Safe Mode.
3. Update or rollback drivers: Once in Safe Mode, open Device Manager, expand Display adapters, right-click your graphics card, and select Update driver or Roll back driver.
4. Disable Fast Startup: Open Control Panel > Hardware and Sound > Power Options, click Choose what the power buttons do, select Change settings that are currently unavailable, and uncheck Turn on fast startup.
5. Repair system files: Open Command Prompt as administrator and run sfc /scannow, followed by DISM /Online /Cleanup-Image /RestoreHealth if the first command fails.
6. Uninstall recent updates: Go to Settings > Windows Update > Update history and uninstall the most recent update if the issue started after an update
