So just recently I was going to install a water system, turned out to have some wrong parts and had to remove 1 of my 2 Nvidia GTX 780s. Since then, I've had the very odd error of the PC not doing anything after it posts. I've reset, DirectKey to get to bios (and it didn't go), reset CMOS battery, removed and reinstalled RAM, reseated power cables, and re-flushed the power of the pc, all with no solution. After enough random resetting and such, it'll finally work and boot up properly.

Occasionally I don't even get a POST beep and it still just stays frozen at the ROG logo with the text below about which keys to enter bios, which do not work no matter how many times I try to press them on my keyboard). Yesterday I reset the system ~15 times before it finally worked.

I've noticed the Boot_Drive LED will light up often too and stay lit when it is "frozen" at the ROG logo screen.

Twice now it's tried to "update" something to end up freezing at the same screen. As I'm writing this now, it has a q-code of 80, which I read something about being Win8 compatible using ACHI, so that seems irrelevant. The manual says that 00 is "not used" and 06 is "microcode loading."

I've been able to load up the bios a couple times by either it having an error, or it somehow letting me load it normally and the settings all are factory default. I tried to use a boot override as well and that didn't work either.

I am at a complete loss for what could be causing this and have yet to find a single thread or post anywhere on the internet regarding this same problem. If anyone could shed some light on this problem that'd be awesome.
