I upgraded my video card from a NVIDIA GeForce 9800 GTX+ to a XFX Radeon HD 7870. I have been running it with no problems for a couple months without ever uninstalling the NVIDIA drivers. Yesterday, I tried to connect my computer to my A/V receiver through HDMI but I wasn't getting any audio. I thought it may be because of the NVIDA drivers so I uninstalled all of them and rebooted. When Windows 8 should have started up, the screen went black and flashes between black and a slightly lighter black. I can still boot up connecting my HMDI directly to the MOBO. I have tried running Driver Sweeper and that did not help. Any help would be greatly appreciated!
