So my xps gen 2 failed after about 3 years of gaming just as described above. The warrenty was expired. Even the bios screen was corrupted and an external monitor showed the same. So I knew it was the card. I sent it to dell, for 250 CAD they mailed me a box for me to put it in and they replaced the 6800 ultra with a 7800 gts. I got it back and ran it for about 5 minutes when it locked up again with the lines on the screen. It would sometimes run for about 5 minutes on windows before crashing. Any 3d hardware acceleration would cause it to crash with the lines. I formatted, that didn't help. Now I am sending it back to del again and they say they will fix it for no cost.
