The Main Signs of a Dying GPU:
The Computer Crashes and Won’t RebootIf your computer shutdown while working in the graphic application or while playing the game and the monitor loses signal there is a high chance the graphic card is soon going to be gone. Some motherboards have hardware detection failure and can signal immediate fail. If when turning your computer ON you are greeted with a blue screen with the message that the signal can not be found or you do not have picture at all it is most likely that GPU has failed.
Graphic Glitches While Playing GamesIf you are playing the game and all of sudden you get off-color pixels, screen flickering, strange graphic behaviors, random artifacts, or similar and that keeps repeating in multiple games it is likely that GPU days are coming to an end.
Abnormal Fan Noise or PerformanceFans are an essential part of cooling the GPU and over time if they are intensively used they could wear out and need replacing. If however you have not noticed and have not replaced the fans card can sustain overheating damage. Many cards have cooling fans that are designed to spin at a higher RPM only when the GPU is under load. It prevents bearings in the fans from dying prematurely, so don’t worry if one of your fans is inactive while you are browsing the web. However, when you play games that utilize software that your card isn’t built to support, the bearings in the fans wear out faster. Once the fans stop working under load, the graphics card can quickly die.
How to Diagnose a Dying Graphics Card
Presented next are essential steps in order to recognize a dying graphic card.
Check Motherboard Error CodesMany motherboards today completely shut down a component that is no longer working. If your graphics card has died completely, this may be one of the easiest ways to tell. If your motherboard doesn’t have display codes, you can try testing the card in a new system.
- Open the computer case: Use your screwdriver to remove screws on the side panel and gently slide it back.
- Locate the error code display on your motherboard: If you have a motherboard with error codes, they should appear near an outer corner.
- Try to reboot your computer: Record each error number you see after you boot your computer.
- Consult the motherboard manufacturer manual for error codes: Open the manual and locate the list for your error codes. If the code matches a graphics processing unit error, your video card could have died.
Check Hardware for Damage or DebrisA graphics card that has damage or debris on the physical parts might quickly overheat and kill the card.
- Remove the screws holding the GPU in place: There are typically one or two screws holding the card to a bracket on the case.
- Unhook the power cords from the GPU and pull the release tab: Remove the power cords from your GPU by pushing in their tabs and gently rocking them out. Once you remove each cord, gently push or pull up on the release tab near the motherboard.
- Inspect the GPU for damage/debris: Check the card for any dirt or debris buildup and clean it out with a Q-tip. You can replace broken fan pieces from the manufacturer.
Test Your GPU Under LoadDownload GPU stress-testing and heat-monitoring software.
- With the card installed, run a stress test.
- As you are running the stress test, run heat-monitoring software: With the stress test running, check your heat-monitoring software for GPU overheating. Any reading over 80 degrees Celsius is too hot.
- Check device manager for outdated drivers: If your GPU is clean, but still running too hot, your software drivers are not installed correctly. To check, type in “device manager” at the bottom of your desktop and click on Device Manager. Find your display adapter and right-click on it to see if it’s working. If your drivers are not working correctly, it is indicated here usually. However, the driver may appear to be functioning even if it says otherwise in the properties.
