I have a ASUS GTX 680 DirectCU II TOP (DC2T-2GD5) and figured I'd flash the bios. I followed the instructions listed perfectly using NVflash and the bios provided in the OP for my card. Once the flash was done, I restarted my computer. While it was rebooting, the POST screen along with everything else was really glitching out. Once I got into windows it got worse. Colors were distorted and I was stuck in 640x480. My GPU wasn't completely bricked and was still being recognized, at least. Obviously the flash had gone wrong so I went to flash back to my old bios but my backup was gone. Now I'm stuck like this. I've tried flashing to many, many different versions of the bios both for my card and other versions (non-TOP) as I was desperate to fix this. None of them fixed the problem. One bios did manage to undo the resolution and color issues but caused intense artifacts. After a restart it would revert back no matter what.
I could really use some help with this issue. I don't so much care for unlocking the voltage at this point over getting my card to at the very least function again.
