GPU troubleshooting is the process of finding and fixing problems with a graphics card, such as fans not spinning, artifacts on screen, high GPU usage, crashes and driver errors. Most GPU problems come from drivers, heat, power or seating, and can be fixed at home in minutes.
What are the most common GPU problems?
The most common GPU problems and their guides:
| Symptom | Likely cause | Fix guide |
|---|---|---|
| Fans not spinning | 0 RPM mode, power, fan fault | GPU fans not spinning |
| Dots, lines, glitches | Overclock, heat, VRAM | GPU artifacting |
| GPU usage at 100% | Normal in games, background apps at idle | High GPU usage |
| Game crashes, driver reset | Drivers, overclock, power | Error occurred on GPUID 100 |
| Black screen, frozen display | Driver hang | How to reset your graphics card |

- Check temperatures; see how to check GPU temp.
How do you know if your GPU is failing?
You know your GPU is failing when artifacts appear at boot, crashes continue after a clean driver install at stock clocks, or a stress test fails. Run the 7 tests in how to check GPU health.
Can heat cause GPU problems?
Yes. Heat causes throttling, crashes and artifacts. Read the GPU temperature guide and how hot is too hot for a GPU.
