Ok here it is. This is my first build and I'm not sure if I done something wrong or not and any help would be greatly appreciated . My build is a Asus Maximus IV Extreme with a I5 2500k CPU and I have two HIS ICEQ Turbos 6970 GPU's. With a Corsair HX850w psu, I have the GPU's in crossfire and when I first fires it up it seen both in the uefi bios , I removed on of the GPU's and later reinstalled and now it don't show up at all in the bios I have uninstalled all the adm drivers after the removal and reinstalled them after I put it back in but to no avail. When I reinstall the catalyst drivers it only see one and lists it and sees the other but not as a 6970 it just says other devices detected Advanced Micro Devices Inc . Thanks for your time and help!
