|Dear Computing 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've throughly cleaned everything, 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, 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!
