GIGABYTE GA-990FXA-UD3 rev. 1.0 BIOS Rollback failure

[Cybertron7]

I took some advice (shouldn't have) of a different forum that in order to play a certain game (Portal 2) I should rollback my BIOS to the first release. That was the dumbest thing I ever did... wow...

Anyway, now my motherboard will not even POST, and I can't access the Q-Flash utility, or even the Failsafe Defaults in the BIOS menu.

Is there a way to manually force the DualBIOS (which the board has) to kick in? My mobo's manual said it should do it automatically after a failed POST and Reboot, but it hasn't worked.

I read somewhere that you can short two pins of your Main BIOS chip, but the post-er said that it was a last resort. I'd like to know what else there might be that I can do.

This is stressing me out, since I just got this build working wonderfully in January...

Any help that anyone might be able to provide me would be greatly appreciated.

I have:
CPU: AMD FX-6100
GPU: Radeon HD 7450
Sufficient RAM (in other words, I know it isn't the RAM that's causing the issue)
620W Seasonic PSU

look at your CPU Supported list for your Motherboard, would you happen to have any of the CPU's listed to work with the F1 bios? if so, pop it in, if not try to borrow one to get your system to post and then update your bios to the newest bios (Or at least greater than F3). second resort would be to try a local computer shop, they should have a spare CPU in the right family, they'll charge you for the service but should be a sure thing.

then failing those then I'd perform the Dual Bios recovery from this post; http://forums.tweaktown.com/gigabyte...ng-failed.html

reason it's a last resort is if you slip you'll blow your motherboard and possibly also lose the warranty too. if you have steady hands then it's worth a try.

what forum would suggest going back to the 1st release of a MB Bios?
