Scenario: Why is my computer screen black?


I have a Lenovo All-in-One and while using my screen went blank. Now the only thing that is visible on the black or gray screen is the curser arrow for the mouse and nothing else. Why does my computer screen go black? Any suggestions ?


A black screen on a Windows computer is a common occurrence that can happen unexpectedly. Typically, this issue can be attributed to problems with the monitor, computer, hardware, or various other factors. To effectively solve this problem, it is advisable to consider each specific situation separately.

3 cases and fixes for computer black screen

Apart from the help-seeker scenario, there are two other situations when your computer screen turns black. In this section, we've grouped these three cases and provided targeted solutions to help you resolve the problem effortlessly.

Case 1. Computer turns on but the screen is black.
Case 2. Computer screen is black after Windows updating
Case 3. Computer screen goes black randomly for a few seconds

Case 1. Computer turns on but the screen is black

If your computer makes sounds upon startup, it indicates that the device is operational. However, if your computer screen remains black, the issue may be related to cable connections, hardware, or drivers. You can troubleshoot it by following these steps:

1. Loose cables and connections: Ensure all cables and connections, like power cords and display cables, are securely plugged in.

2. Faulty hardware: Regularly check for hardware issues, like a damaged graphics card or motherboard, and replace faulty components.

3. Outdated or corrupted drivers: Keep drivers up to date, especially display adapter drivers, but be cautious as updates may sometimes cause screen issues that can be resolved by reverting the update.

Case 2. My computer screen is black after Windows updating

Some users have reported experiencing a black screen problem on their computers after a Windows update, particularly during startup. This issue is also commonly referred to as the "Black Screen of Death (BSOD)". To fix it, rebooting Windows in Safe Mode and Rebuilding MBR can be both effective methods.

▌Fix 1. Reboot your Windows in Safe Mode
In general, Windows BSOD issues are most commonly caused by driver problems. When starting in Safe Mode, only essential files and drivers are loaded, effectively excluding the impact of third-party software or drivers.

Step 1: Press and hold the power button on your PC for 10 seconds to turn it off. Then, restart your PC by repeating this process three times. When you see the "Choose an option" screen, follow these steps: Click on "Troubleshoot," then select "Advanced options," followed by "Startup Settings." Finally, click "Restart."

Step 2: Enter Safe Mode by pressing either F4, F5, or F6, depending on your situation. Follow the instructions on the screen.

Step 3: If you don't encounter a black screen or continuous restart issue in Safe Mode, it's likely caused by third-party software or drivers. To fix this, uninstall them one by one and check if the problem is resolved.

▌Fix 2. Rebuild MBR
Sometimes, an MBR error can cause OS restart issues, including the Windows computer black screen of death. If you run into these issues, it's a good idea to use AOMEI Partition Assistant Professional because fixing MBR can be a bit technical. This software is equipped with a user-friendly interface and clear guidance to help you effortlessly solve complex computer problems.

Step 7. At last, click "Apply" to complete the pending tasks, shut down your computer, and remove the USB drive or boot from the original disk when restarting.

Case 3. My computer screen goes black randomly for a few seconds

If your computer screen briefly went black before a Windows issue occurred and a System Restore Point was created, you can use System Restore to revert your computer to an earlier state, potentially resolving the black screen problem. This feature eliminates changes or issues that might be causing the screen to go black randomly.

Step 1: Enter the Windows Recovery Environment and click Troubleshoot. Then select Advanced options and System Restore in turn.
