Well this one has me completely stumped. A friend gave me his old Sapphire Radeon X850 XT after upgrading to a new card, so I threw it in my rig. After installing the latest version of Catalyst, I tried demoing a couple of WMV HD videos just to see if everything was tip-top. Well, I got a mess of snow and red and blue pixels - the kind of artifacts you'd expect when things are getting a little too toasty inside.
I tried reinstalling the card a couple of times, and one time I ran the WMV HD video BEFORE installing the card (XP detected its presence, but I didn't give it any drivers). Worked like a charm. Picture was crystal clear. Every time I install Catalyst, or just the bare display drivers, the thing goes haywire, but with no drivers it is just fine. Any idea what could cause such a thing? Should I try to find an old version of Catalyst or something?
Setup:
ASRock P45TurboTwins2000 mobo (P45 + ICH10)
Core 2 Duo E6550 2.4GHz
2GB DDRII - 667
