How to: Recover from bad flash with no secondary card or onboard.

fadedmemories · Jun 21, 2009, 05:01 PM

Step 1: Turn your PC on normally.
Step 2: Press f8 and go into safe mode.
Step 3: When you're in safe mode, go into device manager and disable your video card.
Step 4: Restart computer(don't go into safe mode).
Step 5: Flash your card like you normally do.
Step 6: Go into device manager and enable your video card.
Step 7: Restart pc and it will work.
I found this method when I flashed my 4870 and restarted pc by accident. This method worked for me when I was using a ATI card, can someone confirm that this method works for Nvidia cards.

I posted this on OCN and I might as well post it on this forum to help out others.

So the card will work regardless of the BIOS on it?

I thought that when a card had a bad flash, it just will not show any video

When you disable it from device manager, it doesn't really uses the core. The display is all crappy and etc.

I think when a card has a bad flash it doesn't boot into window but shows the bios.

I've had a bad flash that had a garbled screen during POST, couldn't even get into windows...not sure if your tips would work in all situations. I was able to blind flash that card (x1950pro) back to a stock bios, because I had written down my commands and file names, that saved my ass big-time.

the safest way is to prepare a bootable flashdrive with a batch flashing processes that restores a safe/working bios in to the card, when i use to do that kind of stuff, i always made a bootable floopy with the original bios with the whole flashing processes fed in to the autoexec.bat, so incase of a bad flash, i just had to put it in the floopy and boot from it, go have a cup of tea while the videocard was reflashed, and come back to a working machine,
