When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time.

I looked through your motherboard's manual, if your board indeed has a corrupt BIOS, then there's no way to recover it. You'll need to recover the BIOS on the board by using a CH341A BIOS programmer. Again, I'm assuming your BIOS is corrupt, not the processor going bad.
