|After a few minutes (around 20-30 minutes) of playing games my PC would always turn off by itself. Fans and everything are still on though, case fans are running, gpu and cpu as if it didn't really shut down completely, they aren't slowing down either and the pc looks like it is still running the game. I have to press the restart button on the case to open it again.|
I've checked the temps on CoreTemp, my CPU always gets to 59C max (stock cooler and no overclocking). My GPU sits on 60-65C too so I'm guessing that it is a PSU problem. If it is a PSU problem then shouldn't it power off completely and turn off even the fans?.
This PC will never be as fast as yours.
