Fixing Screen issues

Computer screen issues like flickering, black screens, or distorted displays can be caused by various hardware and software problems. Here are some steps to troubleshoot and fix these issues:

1. Check for Loose Connections

  • External Monitors: Ensure that all cables connecting your monitor to your PC are securely plugged in.

2. Update Graphics Drivers

  • Update via Device Manager:
    1. Press Win + X and select Device Manager.
    2. Expand Display adapters, right-click your graphics card, and select Update driver.
    3. Choose Search automatically for updated driver software.
  • Download from Manufacturer’s Website:
    • Visit the website of your graphics card manufacturer (NVIDIA, AMD, Intel) to download the latest drivers.

3. Adjust Display Settings

  • Screen Resolution and Refresh Rate:
    1. Right-click on the desktop and select Display settings.
    2. Scroll down to Advanced display settings.
    3. Ensure the resolution is set to the recommended level and the refresh rate is appropriate for your monitor.

    1. Press Win + R, type msconfig, and press Enter.
    2. Go to the Boot tab and check Safe boot.
    3. Restart your computer. If the issue is resolved in Safe Mode, a third-party application might be the cause.
  • Disable Hardware Acceleration: Some programs like web browsers or video players use hardware acceleration, which can cause screen issues.
    • In Chrome: Go to Settings > Advanced > System and toggle off Use hardware acceleration when available.

5. Perform a System Scan

    3. Wait for the scan to complete and follow any on-screen instructions.

6. Test with an External Monitor

  • External Monitor Test:
    1. Connect your laptop or desktop to an external monitor.
    2. If the external monitor works fine, the issue might be with your original display or its connections.

7. Check for Overheating

  • Overheating: Ensure your system is not overheating, as this can cause screen issues.
    • Clean out dust from vents and fans.
    • Use a cooling pad for laptops.
