I am attempting to have a Xfire set up on my custom PC.
I have just received my new Graphics card which is a Asus HD7770 2Gb Edition and i want to use it with my VTX3D HD 7770 5000 MHz Edition graphics card in CrossFire but for some reason i have set the cards up and after the windows 7 "Starting Up" Screen it just goes into a black screen, the computer is still on and so are my monitors as if the PC was on but nothing.
I have found out that it is caused by a driver issue as i started the computer in safe mode deleted the drivers and run the computer using the graphics cards VGA Default driver and it worked fine but once i installed Catalyst Control Center it automatically installed the graphics cards drivers and bang black screen as soon as they were installed. .
Its like the same driver might be trying to work the GPU's as they are the same (HD7770's)
Any Ideas how to fix the driver issues?

14Gb Ram
Vtx3d Hd7770 5000Mhz Edition
Asus Hd7770 2Gb Edition

I have the latest Catalyst Control Center from AMD (which usually automatically downloads the newest drivers),my motherboard is an Asus P7P55D and my Power supply is a G7 Power Extreme 780W
