Ahhhh! Ok, update: Formatted a few weeks ago, was all good, seemed stable. Then a few BSOD's in games... Now they have gotten regular again, random as before, can be BSOD in game, in a movie, in a screensaver...or when its just web browsing, or doing nothing. They can be with graphics card drivers, USB drivers, or other system files....some are blank errors. Tonight was watching LOST in itunes....about 4/5 BSOD's during it. anyway, going to buy a new PSU on monday, 750W (from a 500W). Will also try memtest again over night tonight. Any other input or advice?
