True but why it got corrupted, that's the question?

My suggestion would be to follow Sajin's advice and flash. Corruption can happen for numerous reasons but it is rare.

Hello,
As previously stated, if another BIOS is working properly, a simple re-flash of the BIOS could help your issue. I am curious however, was this on a new board, after a BIOS flash, or did this issue just start randomly without any hardware / software change?

It's not a new Board, I never had any issue with Bios flash until Bios 1.09 which one I flash it through USB Drive connected to Logitech G19s[Has two USB Port]. My guess is flash it through USB Hub rather than USB Drive that connected directly into rear USB Port caused the Bios corrupted somehow!!I re-flashed the Bios to 1.09 without any issue !!!

Just FYI to anyone updating their BIOS to v1.05 from within Win (8.1) using my delivered v1.02...
After the flash program completed it asked for a restart, and then it just went into a continuous boot loop, accompanied by 6 beeps and a 4F post error code. The manual says that 4F is "DXE IPL is started". No idea what that is.
To fix my bricked BIOS #1 chip, I was advised by EVGA customer support power off, select BIOS #2, power back into windows and then WHILST in windows, select the BIOS switch from #2 to #1 and reflash. This had the same result as above when trying to boot with BIOS #1.
I then took it upon myself to boot into BIOS #2 environment, then physically select BIOS #1 on the motherboard DIP switch, then flash the BIOS #1 from a USB stick from within BIOS #2 environment.
The flash was alot quicker and then the system restarted immediately into BIOS #1 with version 1.05.
Hope this helps anyone in the same circumstance. EVGA customer support should test this/add it to their knowledge base.
Cheers
I just had EXACTLY the same issue last night and used the same technique that @zkanuck and @pinktulip used in the post linked by @Sajin to fix it this morning. Thank you! No changes were made to any BIOS settings. It just happened randomly, for reasons that are not understood. It would still be nice to understand how and why.

Yes BIOS is very sensitive to how you flash it!!!!
The weird part for me is I did not flash it and had not changed any settings. This was also the original BIOS that shipped with my board. But, just as it was for you, it was working normally and the next time I turned it on it wasn't. Very odd. Not sure how it got corrupted. I tried using the clear CMOS button and even removed the shroud for the PCH fan (what a pain in the butt that was) and took out the CMOS battery trying to erase whatever glitch was causing it and doing that accomplished nothing. Nothing worked except for switching it to BIOS #2, booting into the BIOS, switching it back to BIOS #1 while in the BIOS and re-flashing it. Now that I think about it, I did notice in the week or so leading up to this I occasionally saw code FF and halt during POST, but pushing the reset button cleared it. The code FF hasn't been seen again. But, the nice thing about this board is having a triple BIOS. I would have needed to use my SPI programmer or contact EVGA for a replacement BIOS chip if it were not for that excellent feature.

Did you check the Cmos battery voltage when you pulled the battery?
