PC loses video output while fans ramp up and shows “Thread Stuck in Device Driver”
Asked by

Whenever I play a game or leave my computer running, the monitor suddenly loses signal while the system itself appears to stay on. I can still hear Discord audio, but the fans ramp up loudly and keep running. After restarting, I sometimes see a black screen with the message "Thread Stuck in Device Driver." What could be causing this, and how can I troubleshoot or fix it?

This probably isn’t a fan problem—the fans are reacting to a graphics-related crash. The likely causes include the GPU, its power supply, or corrupted/incompatible graphics drivers. Start by removing the current graphics driver completely with a tool such as DDU, then install the latest stable driver directly from your GPU manufacturer. If the problem continues, check GPU temperatures, power connections, and whether the graphics card or power supply is failing.

MellowCedar42: When I try to boot into Safe Mode, the display becomes distorted and the fans immediately ramp up too. Should I attempt the driver cleanup normally instead, or is there another way to enter Safe Mode?
