Is my MOBO toast?

[infin@]

So i spent the afternoon working on my computer installed a bay fan and a few switches for some lights. After I was finished I booted up at defualt settings and everything was fine and dandy. I then shut down and put the side panels on my tower and booted again.... nothing.....wtf. All the fans spin up my pumps start and the leds on my ram dance around for a few seconds and then freeze and thats it. The MOBO light is on so know there is power to the board but when I hit the on switch I get no beeps. No post. just a blank screen. WTF!
I then thought that maybe I had a leak and fried something but found no water damage on the mobo or video cards and there was no smell of burnt pcb plus i had already leak tested earlier this week. I swapped out video cards and displays no joy. I undid all the new wiring and still nothing changed. I unhooked the hard drives, x-fi, dvd rom, lights fans and one pump, still no luck. No beeps, no post, no display. I reset the cmos checked my waterblocks everyting I could think of. My system has been rock solid stable fot the past 10 months and temps were never a problem. See sig for details on my system. Any ideas? Is my mobo fried? It is a year old roughly but a $250 motherboard should be able to stand a little abuse.
I am water coolling the 975x chipset and cpu and did not touch the mobo at all before this problem presented itself. The lights and the fans all work fine when hooked up I just can't get the damn thing to post at all!!
Help please!

Sounds like its time to play a game called, "where's the short?" ... its kinda like "Where's Waldo?" ... have fun!

Other things you could try: re-seating the CPU. Single stick of RAM. Another PSU.
