Hi fellow OCNers. I'm having a critical issue and desperately need your help. The problem is one that I've never experienced before and I have no patience since I'm stuck in a dead-end. I'm on a deadline to submit work tonight stored in my SSD.

First, what happened was changing the frequency of my GPU with MSI Afterburner even by 5 mhz caused flickering. However, there's nothing wrong with the GPU itself, as I can easily max the OC through AMD overdrive and have 0 issues. That was clearly an issue with the software or display drivers.

So I uninstalled MSI Afterburner, and then I thought it's also time to update my AMD display driver because it is getting quite old. After uninstalling the AMD drivers, my display went black. Expected of course, since I'm still plugged into the GPU. So next, I unplugged the DVI from the GPU and into the onboard DVI port. Display immediately turned back on showing my desktop. The AMD drivers had finished uninstalling and it recommended a reboot. I rebooted my PC and I no longer get any display at all, even though I'm plugged into the DVI port on the motherboard. How on earth can I solve this if I can't even see anything?

Specs:

Intel i5 2500k - stock
Asrock Z77 Extreme 3
16gb gskill 1333mhz RAM
XFX HD 6850 1gb video card.
Samsung P2270 1080p Monitor

Do you have a hard setting in the mobo to choose PCIe over integrated video?
If so...put the DVI back in the GPU and see if you can bring BIOS up.

Even if you uninstall drivers windows will use generic video drivers......

Unpluggin power from GPU allowed the onboard graphic driver to be detected. But when I try to install ATI drivers, the GPU is of course course not detected and it refuses to install display drivers.

So after replugging to the GPU and rebooting, for some odd reason the display decides to show now. It is a mystery.

The only thing I can figure is you touched a video cable or power cable or monitor setting during your reboot.
