I recently updated the BIOS on my Gigabyte motherboard Z68X-UD3H-B3 (Rev. 1.3) from F12 to U1n, which is UEFI. The flash seemed to go as it should, however, whenever I try to access UEFI, I get the UEFI Dual BIOS screen, but no menu. It's just a frozen screen with no keyboard or mouse response. I have to plug the keyboard into the front USB ports to get that much. I tried taking my legacy video card out to see if that was a problem, but I get the same thing. I can't even use the boot menu because that comes up frozen and nonresponsive as well. However, the computer still boots and works. Please help!
