Having difficulty installing two radeon hd 4770s in my new build. I plan on running them in crossfire but I can't seem to install even one successfully. Whenever I try to boot with one installed i just get a black screen. Tapping/holding F5/F8/F11 have not worked to boot in safe mode. I disabled the Intel(R) HD Graphics Family and the display driver currently running is "Standard VGA Graphics Adapter." I've tried this with both of my 4770s, so I don't think this is a hardware issue.
My build-
mobo-ASUS P8z68-V LE
CPU -i5 2500k
PSU-corsair TX750M
SSD-Corsair accelerator 30gig
GPU- (2x) Radeon HD 4770
thanks for the help
