thx again for the tips. ill try removing one video card. It seems this started happening soon after i installed SP1 and the new crossfireX drivers. I'm wondering if it has to do with that. Ill try using just one card for now. If that is it. I might just buy the 3870X2 .. i mean its crossfire on one board but not two boards. Also.. i dont see any chip in my board.. like SLI has a chip on some boards you have to reverse if you want SLI mode. I play other games like Crysis and such .. or i would not have a rig like this.
