I have a Sapphire HD 7950 3GB OC that keeps freezing on me. Looking for suggestions/help. Sapphire support wants me to try OCing the MB because testing the card in another machine that was OC'd had it working fine. Tested an nVidia GTX 460 and Gigabyte AMD HD 6950 in my rig and both worked fine....hmmm. Curious. Also tried a fresh Windows install to my SSD and when trying the Windows Performance Index, the card froze. So, not likely a software conflict.

Issue Details - Video card randomly freezes under varying operating conditions. Most typically when 75% through Windows Performance Index test ( Tuning Windows Media Decoding) and right after viewing Yahoo or Youtube videos. Other times seemingly at random.
