Hi and welcome to the Gigabyte Forum.
As you have now updated the BIOS from the original buggy one I would suggest using QFlash or even FlashSPI to flash it again and then syncronise the two versions.
The first thing to do is go to the Gigabyte wesite and find the "Support and Downloads" section
(
http://www.gigabyte.com/support-downloads/support-downloads.aspx).
Select your motherboard and revision number which can be found printed on the bottom left corner of the motherboard.
Click on the "BIOS" tab. This will take you to the BIOS versions download page.The newest BIOS versions are at the top of the page.
Click on your region under the "Download Here" section heading. A dialogue box will then pop up asking what you want to do with this file.
Click on "save" and note where you are saving it to.
Take a USB pendrive and make sure it is formatted with a FAT32 file system. If the file ends with .exe run it, or if it is a zip file Unzip it, and save the files (usually contains 3 files) that you just expanded to the Boot sector or a folder of your choice on this drive and insert the pendrive into a USB port.
Re-boot.
Press the"End" key as the computer is POSTing and you will be taken into the BIOS flashing utility "Q-Flash".
At the QFlash homescreen
disable the
Keep DMI Data option before proceeding.
From there just follow the prompts to find your file and DO NOT TURN OFF THE POWER under any circumstances. It will look for the pendrive with the file on it and use that to update the BIOS.
One thing to note is that the pendrive may show up as a floppy or hard disk instead of a USB drive. Once it has completed you can reboot.
We have since found out that the problem with getting some motherboards to "see" the USB drive is a case of using as small a drive as possible, well at least under 2Gb, and even then some will be seen and some won't. Just a matter of luck.
Next sync the two BIOSes.
Go into the BIOS and on the MAIN page press F9 for system info. You should see both BIOS versions listed, if they do not match please update the backup BIOS to match the current.
To do that, reboot and where you would normally press DEL to enter the BIOS, instead press Alt + F12, this will flash the Backup BIOS with the MAIN BIOS contents. Do not worry when you see a recovery comment, that is normal and means it is flashing the backup BIOS.
