My pc which is running Windows 10 restarts without warning and the pc itself doesn't shirt off. I upgraded the power supply before so it can't be that because it's still doing it could it be overheating?
I upgraded from a 500 watt to a 650psu not a big jump but still. And it only shuts down when I'm playing league of legends . Never any other game or anything else.
Not a bad psu, seems unlikely that it is the culprit. Does the screen just go black? Does audio keep on playing? What are your FPS when you play LOL? have you looked at the temperatures yet?
