Dear Bleeping computer Forum - I have a serious issue with my computer, and i was hoping that you might be able to assist me.
My computer shuts down, out of the blue. No error warning, no anything. It goes straight to black screen. This usually happens when i play something graphic intense. I have noticed that when i run something that requires a lot of work from my computer, there is this wierd, high pitched sound, coming from the tower. I have cleaned the hardware from dust etc. Because i assumed it was a heating problem - I even checked all my temps and everything, and tried running my computer through an intense furmark session with no apparent trouble, while constantly checking temps - No issue there. But as soon as i play anything remotely requiring of my computer, it shuts down - If i forexample play tomb raider, or xcom the time before shutdown is very short, but if i forexample play Dota 2 (a much less requiring game) it might take up to an hour or 30 minutes before shutdown. The more intense, the higher the whining, often indicating a shutdown. I tried to unplug RAM, and my GPU from power (Hard drive aswell), but the whining still persist, on a slightly lower level. This makes me assume that there is a serious Hardware problem.. I just cannot for the life of me, figure out what the problem is.
Any Help would be greatly Appreciated, before i go out and throw a lot of money after the problem
