I just made a new pc build and everything was running smoothly for a day until yesterday my monitor randomly went black screen and the gpu fans started running on high after about a minute or so the pc shut itself off. When I turned the of back on the resolution was stuck on 600x800 and it wasn’t detecting my gpu drivers, I went and reinstalled them and it fixed the resolution problem and started detecting the gpu again. This same thing has already happened 3 times in the past day and I’m not sure what could be causing it considering everything is brand new.
