Fixing Black Screen on a Windows Computer

Quick Fix: Restart the Graphics Driver

The most common and easiest fix is to restart your graphics driver. This can resolve temporary glitches without needing to reboot your computer.

Try this shortcut:

Press [Windows] + [Ctrl] + [Shift] + [B]
Your screen may flicker and you’ll hear a brief beep — this means Windows has restarted the graphics driver.

If this doesn’t work, continue with the steps below.

Step-by-Step Troubleshooting

1. Check Your Connections

• Make sure your monitor is turned on.
• Check that all cables (HDMI, DisplayPort, power) are securely connected.
• Try unplugging and replugging the cables or using a different port.

2. Boot into Safe Mode

Safe Mode loads Windows with minimal drivers and can help identify software-related issues.

How to enter Safe Mode:

1. Turn off your PC.
2. Turn it on and immediately press F8 or Shift + F8 repeatedly (older systems).
3. If that doesn’t work, interrupt the boot process 3 times to trigger Windows Recovery Environment, then:
   • Go to Troubleshoot > Advanced Options > Startup Settings > Restart
   • Press 4 to boot into Safe Mode.

3. Update or Roll Back Graphics Drivers

Outdated or corrupted drivers can cause display issues.

• In Safe Mode, open Device Manager.
• Expand Display adapters, right-click your graphics card.
• Choose Update driver or Roll back driver if the issue started after a recent update.

4. Check for External Display Settings

If you use multiple monitors, Windows might be trying to display on a disconnected screen.

Press [Windows] + [P] and tap the arrow keys to cycle through display modes (e.g., PC screen only, Duplicate, Extend).

Still Not Working?

If none of these steps help, the issue might be hardware-related (e.g., faulty GPU, RAM, or motherboard). Consider contacting a technician or your device manufacturer for support.
