I have an i7-3930K on a Gigabyte X79-UP4, and I'd like to overclock. When the computer boots, I press the F2 or DEL key to enter BIOS, but after pressing the key, it will show the blue background of the UEFI BIOS with a title at the top ("Gigabyte UEFI - DualBIOS"), but none of the menus or settings will appear. I have to press the power button to shut down the computer and restart. I've tried accessing BIOS from a reboot, a full shutdown, and even a cleared CMOS (took the battery out of mobo for 30s and disconnected PSU). Any ideas as to what on earth is going on here? I am running the BIOS F2 version, and the only version above that is a Beta.
