Hi, when i start my pc for the first time of the day. It blackscreens after about half an hour of being on and the gpu fans start running crazy. (When i start the pc the temp is about 24° and when it shuts down it's around 35°)

When i try to start it up again it gives me less time to do something and shuts down faster at around the same temperature. Untill after a few boots, it doesn't even boot and starts going full throttle after startup.

The pc is a few years old and i haven't changed anything before this started happening.

It looks like the gpu thinks it's overheating, but it really isn't.

All help would be appreciated.
