soooo, i just wasted about 2500 bucks on a new alienware (yes i know i could have built a better one for the same price, but im lazy) i got a nvidia gtx 580 in it and the first two days i had no problems at all and last night it started freezing with green lines on WoW and only WoW, my computer isnt to hot i dont think the sensors say its at 22 degress C and most ive seen it had is 29c so, i was wondering what someone thought. God i hope my card isnt fried already lol
