Hi and welcome to the Gigabyte forum.
The first thing i would suggest is to make sure that you are using the latest BIOS version available. If it needs updating then make sure htta you use QFlash not at @BIOS to run the update.
It is also possible that there could be an issue between the two BIOSes. Once you have updated the BIOS to the latest version try synchronising the BIOSes so that if it does revert to the Backup BIOS it will have the same version.
Pleased try not to shout when you are posting as it makes it much harder to read.
I would also advise uninstalling EasyTune.
