Motherboard boot loop

Motherboard boot loop
« on: November 08, 2015, 12:05:38 am »

The motherboard GA-Z77X-UD5H (REV 1.0)  is boot looping. The code displayed on first boot is db and then computer restart. On the second and later boot up the code is  32.

I have tried to boot up from the backup bios. It worked fine. Then i restarted and recovered the backup bios on the main bios and it also worked fine.
But on restarting the computer the main bios corrupted again. Then I again recovered the backup bios. It recovered successfully but corrupted again on next restart.

Now my both bios display db on fist boot. Then on display 32 or 15 in second boot.

My first question is that is it really the BIOS malfunction or any other component is causing it? Second, is there is a way to recover the bios from usb or any other way? or I have to replace the bios chip.
