Hello,
So here is my problem... I have 2 ATI Raedon HD 5770 made by XFX (Trusted Brand) and my motherboard supports Crossfire X. When I go into CCC (Catalyst Control Center) It only shows 1 graphic card. I have the little bridge thing to connect the 2. In Device Manager They both show up. I am Running W7 X64 bit. I have 8 GB of Ram and soon getting 3 2 TB of Space to put in Raid 0. right now i have 500gb of space. My motherboard is a ASUS M4A88TD-V EVO/USB3

Is it a clean install?

Try that and see if it still happens, if it does then either the CF bridge is bad or one of the cards is defective

Install each card individually and see if they both function.

Yeah, even though they both show in the device manager it would be a good idea to make sure they both play games well on their own. Also make sure there are no options in the bios for dual cards. I don't know if that is done nowadays but it used to be. It has been a while since I have had dual cards.
