I'v recently had to buy a new video card since my old one burned out.. I got the ATI x850xt and it runs great, for about 5 min then my computer locks up I'm workin on a complete fresh install bios is up to date and I'v tried multiple different drivers. I can't seem to figure out why I keep locking up.. it doesn't happen unless I start playing any of my games like everquest 2 or battlefield 2.. I'd hate to get a new one cause like I said it runs great.. till I lock up hehe so if anyone out there has any solutions I can try please could definetly use it.. its not overheating either nothing seems to be wrong at all.. but anyway any info I can get on it would be most appreciative
