Computer Hangs During Boot at USB Input

So I've had this problem for a while and, for the most part, I was able to coexist with it using EasyBCD. The gist of it is that when I boot the computer, and try to give it any sort of input, be it 'del' to get into bios or 'any key' to boot from a CD, it hangs. Indefinitely. And I'm forced to hard shutdown the system. The computer works fine (despite for a few other errors I've been having, curse you 0xc000007b!) if I don't give it input and just let it boot. This has been bothering me for a really long time and any help at all would be greatly appreciated.

Well, here's my system specs:

Don't know if that will work or not...

Edit: I just realized that's rather lengthy... Here's a condensed version:

Windows 8.1 Pro 64-bit
Intel Core i7 3820 @ 3.60GHz
Gigabyte Technology X79-UP4
16.0GB DDR3 (Kingston 4x 4gb)
2 EVGA Gtx 670 superclocked version. (2gb Vram in each)
1.5tb hdd


And also, can't I reset the BIOS by removing the CMOS battery for a while?
bugcheck 0xc000007b INACCESSIBLE_BOOT_DEVICE
I would be checking my cables and maybe change my sata port.
enable hotswap in BIOS if I had the setting.

If you have a SSD as the boot device, I would look for a firmware update or boot into BIOS to let the TRIM and GC functions complete. (provide power but do not use the drive for a hour or two)

If I had a HDD (not running raid) I would run a hard drive test and look at the S.M.A.R.T. data to check to see if the drive is in the process of failing.

I apologize if I confused you at all, the 0xc000007b problem occurs when trying to run certain programs after boot, when I'm logged in. As for enabling hotswapping, I can't because I cannot access the bios because the computer freezes when I press delete to enter it.

Oh and thank you for the quick reply :)
 
describe the hardware. Windows is not loaded when you try to get into BIOS. If that fails you might have other issues.
(some OEM do not use the delete key to get into BIOS, f2, f10,f12,...)

-sounds like you really need to reset your BIOS back to defaults, this will make the machine rebuild its list of hardware that it then sends to windows.
-generally you will not get the 0xc000007b error after the boot loader starts up unless you have ceratin BIOS issues or your system is loading a corrupted driver for your boot device (incorrect raid driver would be the most common, or corrupted storage driver on the file system)

basically, you need to describe your hardware.

- you might consider unplugging devices or moving ports until you can get access back into the BIOS. you can even unplug hard drives, they are not needed to get into the bios and reset it and configure the hardware again.

Good news! I have managed to solve to problem. Using the GIGABYTE program @BIOS I flashed my BIOS with the latest version, effectively resetting it. It posted, re-acquired the devices and now I have no problem accessing the BIOS. That's one problem down... Now on to deal with the 0xc000007b error.

And thank you, johnbl, for your advice. I really apreciated it.
