I have the same mobo board as you, and i have gotten something similar to the problem you are having now, but this is how i fixed it.
Load up your pc and go into your bios. Under Advanced settings, you should see Northbridge configuration.
Under Primary graphics adapter, you should also see where you can set the default Gpu to onboard.
You should now be able to boot up your computer with the bad Gpu installed in your pcie slot. Make sure you put it in the frist one, and do not add any other gpu in ther, if you have any, take them out.
Now you should create a DOS readable usb with this video guide http://www.youtube.com/watch?v=fR8656az8sU&feature=player_embedded
, i found this as the most efficient way to flash a bios.
keep the files in the video, but Do not use the Nvflash that comes with the video, i had some compatibility issues flashing my cards with it. Go to your Gpu's manufacturers website, and download the latest bios update for your card. It will come with a lot of files, but all you need to do is to replace only the items you downloaded from the video guide, with the ones you downloaded from your Gpu's vendor's website. E.g, replace Nvflash, CWSDPMI, NVIDIA.BAT, nvflash.doc etc, with the new ones that come with your vendors Bios update download.
Among the Bios file you download from your manufacturer's website, there will be your ".ROM" (bios file). Rename it with "680.ROM".
Put all the files together in the DOS usb flashdrive you created, and reboot your system. NOTE: that the DOS usb drive must have the following files. Nvflash.exe, CWSDPMI, NVIDIA.BAT (settings file), nvflash.doc, and 680.ROM. I don't think the "readme" file is essential, but you can add that too.
When you restart your system, Hit "F11" to go into boot menu, and select the thumb drive, it should boot up into dos.
Then type this command "Nvflash -4 -5 -6 680.ROM"
It would ask you if you want to continue, and you should enter "Y"
The flashing will begin. Might take 1 min or two, depends. Then it should say "flashing successful." And you can reboot. pressing Ctrl+Alt+delete
I think after flashing, it's best to hit cmos button at the back of your case. then hit "F2" and go into the same settings as before, "North bridge" and set the default to Pcie" and move your Dvi, or Hdmi cable to the 680". When you boot into windows. Everything should work fine
While flashing, if you get any errors, take note of them, or even take a picture, so i know how to help. I hope you don't run into any errors. Cheers! Edited by Yungbenny911 - 11/28/12 at 7:02pm
