If I hit the <End> key during the POST or pressing the <F8> key in BIOS setup menu, nothing happens.
I didn't brick it with bad bios flash.


When the problem occurred, it corrupted both the main and backup BOIS, I don't know if the BIOS was clean or had malicious...

Gigabyte BIOS naming conventions, that would be the GA-X79-UD5 motherboard, BIOS version 14e



So no, using Q flash isn't an option...
