If the issue persists, consider updating your display drivers or trying a different graphics card if possible. Ensure that the cables and ports are clean and free from dust or debris.

By verifying the cable and port integrity, you can eliminate potential hardware issues and narrow down the cause of the random black screen problem on your PC.

Adjust Power Settings

If your PC is experiencing a random black screen, adjusting the power settings may help prevent this issue from occurring. By modifying the power plan to optimize energy conservation and prevent the display from turning off unexpectedly, you may be able to resolve the problem. Adjusting the power settings can also help to reduce heat and improve the overall performance of your computer. Experiment with different power settings to see which configuration works best for your PC.

Update or Reinstall Graphics Drivers

To update or reinstall your graphics drivers, first identify the manufacturer of your graphics card (Nvidia, AMD, etc.). Visit their website and search for the latest drivers for your specific model. Download and install the drivers, following the on-screen instructions.

If you’re using Windows, you can also use the Device Manager to update the drivers. Right-click on the Start button, select “Device Manager,” then expand the “Display adapters” category. Right-click on your graphics card and select “Update driver.”

If you’re experiencing a black screen issue, outdated or corrupted graphics drivers could be the cause. Updating or reinstalling them can often resolve the problem.

Resolve Overclocking Complications

Another solution is to clean the inside of your PC to remove any dust or debris that may be causing overheating. Overheating can lead to a black screen, so ensuring that your PC is free from dust and properly ventilated can help resolve the issue.

If you are still experiencing random black screens, it may be worth checking for any hardware malfunctions such as a faulty graphics card or monitor. Consider testing your PC with a different monitor or graphics card to see if the issue persists.

Manage Graphics-Intensive Applications

  • Close any unnecessary graphics-intensive applications
    • Open Task Manager by pressing Ctrl+Shift+Esc
    • Look for any applications using a high amount of CPU or GPU resources
    • Right-click on the application and select “End Task” to close it
  • Update graphics drivers
    • Open the Device Manager by pressing Windows Key + X and selecting “Device Manager”
    • Expand the “Display adapters” section
    • Right-click on your graphics card and select “Update driver”
    • Choose “Search automatically for updated driver software” to install any available updates
  • Adjust graphics settings
    • Open the graphics control panel for your graphics card (e.g. NVIDIA Control Panel or AMD Radeon Settings)
    • Lower the graphics settings for specific applications that are causing the black screen issue

Inspect Power Supply Adequacy

To inspect the power supply adequacy, check the power cable and ensure it is securely plugged into the PC and the power outlet. If you are using a surge protector, try plugging the PC directly into the wall to rule out any issues with the protector. Consider upgrading to a higher wattage power supply if your current one is insufficient for your PC’s components. If your PC randomly black screens, inadequate power supply could be the cause, so it’s important to address this potential issue.

Address Potential Monitor Damage

Next, check the display driver on your Windows 7 operating system. Update or reinstall the driver to ensure it’s functioning properly.

If you’re still experiencing the black screen issue, try adjusting the brightness and screensaver settings on your computer. Sometimes, these settings can cause the screen to go black unexpectedly.
