Just got a BFG 6800OC for a new build. Athlon 64 3000 and DFI K8T800 Pro board. Card works fine until I install the video driver. Then when Windows loads the screen gets distorted and the monitor goes into stand by. I tried it in my main system with same chipset with same results. I then installed it in a system with nForce 3 and it wouldnt even boot. Then installed it in my old XP 3200 system with nForce 2 board and it worked perfectly. Im stumped. Ive used various 6800 cards in these systems with no problems.
