Can't access BIOS on Intel DZ77BH-55K motherboard

I've been unable to boot into my OS for about two days now, and I wanted to go into the BIOS to see if I could boot to a USB drive. When I press F2 repeatedly, or hold it down, I never get into the BIOS. It just hangs at a black screen with an E7 code on the motherboard (waiting for user input). The only input that does anything is Ctrl + Alt + Delete, which causes the system to reboot and start the same process all over again.

Does anyone know how to fix this issue?

Yes I do. It came pre-installed on the motherboard.
