I went away for a few days and unplugged my system (everything, protectors and power strips included) from the wall, came back and plugged it in and nothing.

When you hit the button; fans take a half turn (if that), LED on Titan video card lights up similarly, then it stops.

I've done the PSU test (simulating mobo) and it runs and starts all drives.

I've pulled video card and RAM, installing only one stick of ram, no change.

About the only thing I haven't tried yet that I've come across is reseating the CPU. Since that is obviously a bit more work requiring complete removal of everything, I thought I'd ask here just in case there is some known issue or something I've missed.

Obviously nothing should have changed because the system was working fine until I unplugged it from the wall (to protect it, how ironic).

Please make my day and have an easy fix for me. :)
 
Unplug the system from the wall (no AC power connection) and reset the BIOS. Then plug it back in, and try booting. Your CMOS battery may be low and there may be an issue with the BIOS. I would doubt that reseating the CPU would solve the problem since it was working prior to this.

I did actually already replace the battery, just happened to have one here. Didn't reset the BIOS tho, so I'll give that a shot.
