Same here, board is dead with F3A.

It runs fine for two days with that BIOS. Yesterday i want to turn on the PC -> BlackScreen, fans @ 100%

After a few restarts it says "Recovering from backup-BIOS" -> Restart -> PC hangs @ CPU/RAM detection, Clear CMOS doesn't help. So, back to the shop

Until the mobo is repaired, i will try the asus M3A32-MVP.

It's not the first time GB has an official broken BIOS. Think of the F6 for the P35-DQ6
