I've looked all over and can't find a fix to this issue. I recently purchased two ATI Radeon HD 6950 cards, both in perfect working condition, and alone run fine in my PC, however once I try to crossfire them my PC won't boot. Nothing comes up on the screen, none of the peripherals flash, however the PC sounds as if it is running, the Cards cycle between the fan at max and resting speeds, and the Q-code cycles through all of the boot/ini codes.
I've tried running it with both cards not connected, but it doesn't work either. The PSU (900w Antec) is supposedly Crossfire ready (http://www.newegg.com/Product/Product.aspx?Item=N82E16817371050), and the board (Crosshair V Formula-Z) is Crossfire ready. I've gone through the bios and can't find any option that would be blocking this and the correct drivers are installed. Any help?
