First of my system specs:
Motherboard: Gigabyte F2A85X-UP4 Original BIOS version: F2
Processor: AMD A10-5800K @ 3.8ghz(stock)
GFX card: HIS HD6570
RAM: 4GB 1333mhz Team Group memory
OS: Windows 7 64bit

Details:
The motherboard was an upgrade from an A55 motherboard and I've just installed a Windows on it. I then updated all the necessary drivers like audio, graphics, and others. Then I downloaded the latest BIOS driver from Gigabyte, which is version "F4".

I used the QFlash utility in the BIOS as per instructed on the motherboard's manual to install that driver. I rebooted, load optimized defaults and let Windows load. I reach the login screen and typed my password. It was taking its time loading then the rotating blue halo stops and the system pretty much hanged. After a while it rebooted and same thing happens when I log in.

I've just now reset the BIOS driver to the factory default of "F2" and everything's fine. Should I just stick to this default driver or is there something wrong with how I installed it?

I'm planning to overclock my processor when these things settle down.

Thanks for the reply.
I've already tried clearing the CMOS and it's still the same issue. Oh well, I've already reverted to the default F2 driver version and have already OC'ed my system. I still try updating it to F4 once I finish tweaking my system a bit, will give an update about that soon-ish. Other suggestions for solving the issue is greatly appreciated though.

UPDATE: I've tried updating it to F4 again then clearing the CMOS and loading optimized defaults. Still the same issue with it freezing/hanging when I try to log into Windows. I'll try once more but this time with the F3 BIOS version. Will update later again.

Just tried this with the F4 BIOS version. I was able to log in and reach the desktop, however, after a minute or two it hangs then reboots. Also there's a slight increase in the loading of the log in screen. Do I even have to update the BIOS though? I thought maybe it could improve the performance a bit and on Gigabyte's website it states that the F4 BIOS version allows for Richland support, the descendant of the Trinity APUs.

Anyway I'll try the F3 next.

UPDATE: Tried it with the F3 BIOS version. Works fine and I didn't have to change the SATA settings.

Ah. I guess I shouldn't even be messing with it in the first place. Lesson learned, though now that I've updated it to F3 and not having any issues at all I will stick to it. Thank you very much though.
