Re: 6800GT Dead?
put that card in a different system. Sometimes when there's a problem with the driver there's a problem with the whole system. My dad's system would lock up all the time like you say, but in windows. He got the blue screen, and nv_disp failure also, and when I formatted it for him, the problem went away. He was using a tnt2, but that's proof that it may not be the card, but windows itself.
again, just put it in your friend's system or something and see if it'l tick.
EDDIT: like you, we tried a ton of drivers before we formatted, and had no success. after the format, the problem went away.
