I have around 250 hours in ams2 and around 100 hours in pc2. I already experienced a few times that my gpu got deactivated by those games. It always starts with a long black screen with my monitor saying no signal. Then I hear the windows unplug sound and my pc restarts. once my pc turned on I always need to use my integrated graphics driver to activate my gpu. Afterwards I need to restart once again and reinstall all amd drivers. This is very frustrating as this happens quiet frequently probably also damages my gpu. Does anyone know why this happens and if theres anything I can do about it.
Sounds more like a hardware issue. Probably a GPU issue. Check Windows Event Viewer for any messages correlating with those crashes. You could try underclocking your GPU to reduce load.
More than hardware it looks a GPU drivers problem to me. Try reverting to latest working GPU drivers and give it a go.
Might as well that the fans aren't working. That it shut downs any program to prevent the GPU from getting damaged. Download DDU, install the drivers, etc etc. Check if the cables are properly attached to your GPU. Make sure you've enough PSU power or try another PSU.
