I just finished my new system a couple days ago and it was working perfectly. Rampage IV Formula, 3930k, GTX 780 SLI, H100i, etc. I installed and updated absolutely everything. I did stress tests, played some games, all kinds of great stuff. I go to boot up it up today and no display. I also have the red vga led on the mobo. Long story short, here's what I've done so far. I removed all ram but one stick and one gpu. Same problem. Flashed bios. Reset cmos. I moved the gpu to slot 2 and it worked fine and booted. Slot 3, same thing. I totally reset the bios, updated it again, and updated everything again. I move the gpu back to slot 1 and same problem. Red vga led and no display. The error code panel says 62, and about ten seconds later AE, and another ten seconds later AA. Strangely enough, I get A2 sometimes. I don't do anything different, I just get A2.

I'm lost. I've tried every trick I can think of. I've flashed bios, cleared cmos more than once. I'd really appreciate any help. I just got the mobo a couple days ago. Everything else is pretty new too. THANKS for the help in advance. Also worth noting, I've read tons of other threads with similar problems with no help. Both gpus are working since I can put either of them in slot 2 or 3 and it works. If I put both cards in, but connect the dvi to the bottom card, bios doesnt detect anything in slot 1. I'm...so lost here.
