Asus P8Z77-V Pro Startup Failure

Hey everyone, I've run out of ideas. Any help would be much appreciated.

It is a new build but the system was running flawlessly for a few hours (I was running games with safe temps on CoreTemp etc.). Everything was stable but I wanted to do a better thermal grease application so I turned off and unplugged the system. I then removed a stick of memory in order to get the heatsink. I removed it, reapplied AS5 thermal grease, put the heatsink back on, put the memory stick back in, and then this happened:

PROBLEM: No picture is coming up on the monitor. Basically it flashes a black screen like it is going to start then the monitor goes idle. It won't even go to bios. The "boot device led" is lit up red.

I tried reseating my memory. I tried clearing CMOS. I tried removing the battery for 45 mins. I tried unplugging everything besides 1 stick of memory. No luck so far.
