ok first off i have very limited knowledge with computers. My problem is, 2 days ago i wiped my HD and reinstalled vista and all, but ever since while im doing random activities on it, including trying to type this the 1st time, it just randomly cuts the computer off. i get no message or anything, just instantly powers down. i never had this problem once before i wiped my HD, could i have not installed an important driver or SOMETHING to cause this? i really need help its so frusterating that ive been trying to install a new game on my pc ever since and at random times wether it just started installing or after an hour when its almost done that it just cuts off. I saw where some people talked about heat, but i cant understand if its never done it before and now it does how that could be heat related. please help me fix this problem
