Crossfire (or DFI MB?) problem

[elbarto]

So I just reciently got a crossfire setup. I am running a built by ATI x1900 CFE and a Sapphire x1900xtx on a DFI Lan Party 3200. I did a fresh install of WinXP SP2 and got all the updated drivers for everything. Now yesterday I installed Ghost Recon: AW and when I tried to run the game on default Catalyst Control Center settings (ie. Catalyst AI enabled) the game started to load and change resolutions and then the system powered off. I turned it back on and everything seemed fine and all. No error messages. Now I tried running GRAW with Catalyst AI off and had the settings on relitivly high. (10xAA, 8xaf, etc.) GRAW started to load but then it crashed with the following error message:
--
Crash in application version: grpcrc1.02

Error in archive settings\defaults.xml

SCRIPT STACK

I'm thinking it may be a PSU issue, but I have a Crossfire approved 550Watt PSU so ?
Any Ideas?
