I get a black screen after working a few minutes on blender with the Cycle render method active. Most of the time I have a second window of blender open, set to a camera with Viewport Shading on. Until today there weren't any problems with that.
Now, like I said, I get a blackscreen after a few minutes without error message etc. and on top of that the USB power goes out on the computer, it would still be on but none of my display show anything and I can't do any shortcuts. The USB back- and frontports are affected by that. So I have to force shutdown the computer.
I only get this kind of phenomenon with blender. Here is what I tried:
Working without the cycle render window, everything works just dandy. No blackscreen, no errors, nothing.
I reinstalled blender multiple times, on different drives (C:/D:). I used 2.91, installed 2.83, installed the Steam version, on all versions the same behaviour.
I reinstalled my graphics card driver with Geforce Experience and over the device-manager, even completely reinstalled my whole Windows system. Same issue.
The event viewer doesn't give me any info I can work with and no further error messages are displayed after a restart.
I can run a GPU benchmark and bring the GPU to 100% for a prolonged time without any problems.
