If your computer screen turns black while you are using your graphics card, it is most likely that the graphics card is failing due to a faulty connection or hardware failure.
Below are some troubleshooting steps you can take to try and resolve the issue yourself:
1. Check all cables and connections: Make sure that all of the cables connecting the graphics card to the computer are plugged in tightly. Also check the ports on both the graphics card and the computer for any dirt or damage.
2. Test the monitor: Try connecting the monitor to another computer or device to see if the problem persists. If it works on another device, then the issue may be with the graphics card.
3. Check the power supply: Make sure that your computer is getting enough power to run the graphics card. If the power supply is inadequate, it could cause the graphics card to fail.
4. Clean up the graphics card: Dust and debris can build up on the contacts of the graphics card and cause it to malfunction. Use compressed air to clean out the dust and debris, paying special attention to the contacts.
5. Update the drivers: Outdated drivers can cause compatibility issues with the graphics card and the operating system. Visit the manufacturer’s website and look for the latest drivers for your card. Install the drivers and test to see if the issue has been resolved.
6. Reinstall the card: If all else fails, try removing the graphics card from the computer, cleaning the contacts with an eraser and then reinstalling it. This will help to ensure that the card is firmly seated in the slot and has a good connection to the motherboard.
7. Replace the graphics card: If none of the above solutions work, it is likely that the graphics card itself is faulty and needs to be replaced. Make sure to buy the correct replacement card, as the wrong one may not fit or work correctly.
If these troubleshooting steps do not resolve your issue, contact the technical support team of the graphics card manufacturer. They will be able to provide more accurate advice as to the cause of the issue and a solution.
