I cannot speak English.  :'(
It is the first contribution.
If it is going to start PC, it freeze by ledcode78.
I think that it is failure of BIOS.
The basis of Dualbios is also the same as two.

BIOS Recover Method Via Manually Invoking BACKUP BIOS Auto-Recovery
 Using Power Supply - On/Off Switch

 It is possible to make the BIOS Auto-Recovery kick in (Dual BIOS) and re-flash the MAIN BIOS with the contents
 of the BACKUP BIOS.
 
This is a simple and easy method for anyone to try before having to resort to other more difficult methods,
or a RMA.
 
1. Shut off the power supply using the switch on the back of the PSU, wait 10-15 seconds.
 2. Press and hold the case Power On swtich, then while still holding turn on the power supply from the switch on
the rear.
 3. Still holding the case power on switch, the board will start, once it does release the case power on switch
and shut off the power supply via the switch on the rear of the unit. (Do the latter two parts as quickly as you
can once the board starts)
 4. The board will shut down.
 5. Turn the power supply back on using the switch on the rear of the unit.
 6. Turn on the motherboard by pressing the case power on button.
 
Once the board starts this time you should see the Gigabyte splash screen, or POST page, then the Auto-Recovery
from Dual BIOS will kick in. You will see a checksum error, and then recovery from BACKUP BIOS will begin. Once it
is done reboot your machine and enter the BIOS and load optimized defaults then save/apply/reboot back to BIOS.

Now you are done, and will be using whatever BIOS was in your BACKUP BIOS, From there you can attempt whatever you
were previously trying, or update your BIOS to the latest version.
