What I've tried, Cleared CMOS, tried three identical video cards, all which checked out fine at Fry's. The really don't like me now. Started with a 580 Watt PS and changed to the 850 with no luck. ASUS claims the motherboard should handle the card. ATI in non committal. Updated BIOS. Newest version is dated 11-07.
