Possible to BIOS roll back?

[Shisimona]

I posted something about 1.5 weeks ago with having issues when gaming. Last night I seen Asus had a bios update for my Prime X470 Pro. So I downloaded it. Well about 2 hours ago, I flashed it to the new 5809, was 5601 before update. After it flashed. Message popped up saying it was successful, I clicked restart. It restarted and told me to press F1 to enter setup. Went into the BIOS to make sure it flashed proper and everything was in order. I exit to boot into Windows. While it was booting, it came up keyboard not detected but yet it was fine after the flash as it prompted me to press F1. Then the system restarted. Okay. Restarted. Came up with keyboard not detected again and it started to loop restart. Turned on system, turned off power supply and unplugged it. Pressed power button to drain any remaining power in the system. Pulled the CMOS battery out for 10 mins. Put it back in and it started fine. Booted into Windows. I then restarted to make sure everything was in working order. But while it was restarting, keyboard not detected popped up again but this time it booted into Windows and my keyboard was working.

I restarted again, keyboard not detected popped up again and started to loop again. Pulled the CMOS battery. 

I was finally able to get into the BIOS after the 2nd CMOS clear. No settings were changed after I flashed the BIOS to 5809. 

After I exit the BIOS the 2nd time, keyboard not detected popped up once more. Clear CMOS for the 3rd time and everything was fine.

It seems for it work proper right after this flash is to Clear CMOS everytime I restart my PC. 

It is possible to roll back to 5601 or could this be a sign it's time to replace it? I've always had issues with flashing the BIOS with it.

Edit: Just checked the Asus site again and seen they have a new BIOS 5837 that was posted on there a few days ago. But yet wasn't there when I checked last night.
