I've been using this comptuer for about one year. It mounts the following hardware:
nForce 6 680 SLI
nVidia 8800 GTS 640
Vista 64 Business
It has been running smooth and nice for the whole year, normal temperature on the card would elevated to 80-90 celcius on load.
Yesterday though, as I started a game on Left 4 Dead, I started seeing red dots, black cubes and purple/cyan lines all over the screen, until the whole computer froze, then I had to reboot manually. Upon restarting, I got a BSOD.
I am now running Vista in safe mode... I tried updating my GPU drivers, nForce drivers and still no success. Sometimes I can boot in normal mode, but it only takes a few mins before I start seeing the red dots all over the screen before it freezes. Its very cold here and the GPU temp is sitting at a steady 67 celcius now. The GPU fan is running.
