My PC shuts off I mean it suddenly goes to "off" state it doesnt even show the shutting down screen. It turns off like power is cut even though there is no prblm with power. Idk if it is a software or hardware problem.It crashes after 2min in the first startup and then the time goes on decreasing . then it never even goes to bios until I leave it for a day or so. I don't think it is a heating issue. And its not a PSU failure too because I tested it with another working PSU.and my motherboard also went to a service for the same issue and I received it today and I have the same prblm again. I am really not happy with their repair so I came up here. Somebody please help me! I can't live without my PC.
