Sabertooth Z77 won't post

I've been assembling a new gaming computer, but ran into a problem. Firstly, I've got everything hooked up correctly, however, my motherboard seems to be displaying a red LED, which I'm assuming is indicating a problem. The computer boots up fine, fans running and whatnot, but my monitor just stays on standby. Please find the attached files that display my problem. I'd appreciate any input. I've tried clearing the CMOS, swapping out the graphics card, and plugging and un-plugging drives, but it stays the same. Any help would be appreciated.

That seems to be the boot drive led, had the same issue last week. Had to cycle the monitor on and off to get it come up. It should be waiting at the oc failed/run set up screen. Hit f1 anyway and see if the screen wakes up or not.

Youre positive you hooked it up right? But you never checked the manual?
