I have a Q6600 running @ 3.2Ghz for the past few months. It was just another ordinary day and i loaded speedfan to check some temps. Suddenly my pc turned off. It tried a couple of times to boot on its own but it wouldn't post. I turned it off, and then power it up again and it worked. When i loaded some programs though everything was reporting that i had only 3 cores.
It's still covered under guarrantee so i ll probably just return it but does anyone have any idea of what happened and if it's reversible?
