Powercolor Radeon HD 4870X2 Crashing w/ Catalyst AI Enabled!!

Forum Graphics & Displays : AMD Radeon Powercolor Radeon HD 4870X2 Crashing w/ Catalyst AI Enabled!!

Hi all, I just spent quite a good deal of money building this system the past week.

I've been pulling my hair out with this problem where I can't run any games (have tried Crysis, Trackmania Nations, HL2) with Catalyst A.I. enabled (BSoD saying the ATI driver is in an infinite loop), which basically means I can't use the 2nd GPU on the card. It works in windowed mode but that's because it's not using the 2nd core.

Obviously, I can turn off CAT AI and games will run fine but performance takes a huge hit as you can imagine. Also, running 3DMark Vantage gets me a blackscreen and a reset.

Here are my specs:

Antec 1200 Case
Intel Core 2 Quad 9550 2.83GHz
8GB DDR2 G.Skill RAM 800MHz
Asus P5Q Pro mobo
PowerColor 4870X2
2 Seagate 360GB SATA HDDs
Corsair TX750W PSU
Windows Vista 64-bit SP1
Catalyst 8.10 final

Any idea what could be conflicting with the Cat. A.I.? When I try to run games with the AI enabled, I get a BSoD (driver is in infinite loop it says) and/or a blackscreen then reboot.

Things I've tried:

Fresh install of Vista and all updates/SP1
Updated all mobo drivers
Fresh install of Catalyst 8.10 final
Swapping out various DIMMs
Torture test my CPU/RAM for stability

I'm about to go nuts trying to figure this out.

Thanks for your time and help!

Try older drivers.
