GTX 770 BIOS FLASH HELL (SOLVED. Close thread.)

post #1 of 2
Thread Starter 
Yesterday I did a BIOS flash with some modified boost clocks for my 770. For some reason, I get a picture right until I would be booting into Windows. I see the BIOS splash screen, the Windows 8 boot screen (with the spinning dots), and then it goes blank and never comes back.

In an attempt to recover from the faulty flash, I created a USB stick with DOS on it to use NVFLASH so I could flash the original copy of my 770 BIOS back onto my card, but the latest version of NVFLASH must be run inside of Windows. When I try to run the latest version of NVFLASH in DOS, it says something like "this program cannot be run in DOS mode."

If anyone has ANY idea how I can get my original 770 BIOS back on my card I would be extremely thankful.

I have these PC parts available if they could be useful:
-latop
-USB stick
-Windows 8 Retail Installation Disk
-Windows 7 Retail Installation Disk
-Windows XP Retail Installation Disk
-onboard integrated graphics
-multiple PCIE lanes in my PC
-GTX 550Ti (if a card swap is necessary)

Basically, I either need to get back into Windows (and be able to see what I'm doing), or I need to find a way to run the latest version of NVFLASH inside DOS.

PLEASE PLEASE PLEASE HELP.

Though I didn't want to lose my data, I went ahead and did a clean install of Windows 8. Right after the install finished I was able to boot into Windows and run nvflash and get the original ROM back on my card.

Will install NVIDIA drivers and see if everything is back to normal.

Edit: All good in the hood.
