well I bought a 7900 gt from evga when it first came out, and i just now thought about it, i have random crashes in games like ill be playing battlefield 2 or rome total war, any large graphic game itll just crash randomly it ownt say a thing just it disappears and im at the desktop. Is this form the video card? Also in warcraft 3 sometimes I have these white pixels that are all over the screen in lines is this artifacts?
