Ok so here's what happened: 1. I flashed the bios on my PowerColor 1GB Radeon 6950 using WinFlash a few times trying to unlock shader clocks. A couple of those times i forgot to flip the bios switch to position 1 but position 2 should be read only? 2. BSOD on startup in both bios positions (1 and 2). Tried removing drivers in safe mode and system restore to no avail. 3. Reinstalled Windows 7 64 bit successfully 4. Installed 64 bit video drivers with bios switch in position 2 but it's still BSOD on startup with atikmdeg.sys failure. 5. System restore to remove video drivers, boots successfully. 6. Tried reinstalling drivers in position 1 with the same result. I must have somehow overwritten the default bios in position 2 but to flash back to the default bios WinFlash needs video drivers installed!! Catch 22 what to do? If anyone has any suggestions I would greatly appreciate it! Thanks in advance -Dom P.S. Is there any way to flash the gpu bios without the video drivers installed? New info: 1. Tried installing my GTX 465 + drivers and it worked. 2. Tried using the integrated motherboard graphics to flash the bios without actually using the card. My motherboard doesn't let me get past bios saying that I can't use integrated graphics with a video card installed. AHHH! 3. Tried blind flashing the bios from a bootable usb but 'atiflash -i' couldn't find any compatible display adapters.
