Sapphire Raedon AMD GPU not detected by Asus MoBo (win7 64)
As the title says my Sapphire Raedon HD 6970 (AMD) GPU is not detected by my Asus M4A78LT-M LE motherboard. This would be simply a problem with the pci port or faulty hardware normally from most of the posts i have read.
However, as I do not have a VGA cable to test the inbuilt graphics card, I connected through the HDMI port on the GPU to my screen, when I get into the windows device manager it is saying that the GPU is non existant, and the screen performance is choppy, I have updated the GPU drivers and the BIOS, I honestly have come to a dead end here, any assistance at all would be helpful, thanks.
PS. this is a fresh build, fresh hard drive with win7/64 8GB ram + AMD Phenom II x6 CPU
