Broken motherboard? Advice needed.

[diddlina]

I have a nForce2 IGP K7N2GM-L mobo that I got back in March. So far it has worked perfectly for me. Last night I took out my cd-rw drive to replace it with a new DVD-rw drive. When I hooked everything back up my computer would not boot up at all. No MSI screen nothing. No signal to monitor.

MSI nForce2 IGP K7N2GM-L
Kingston DDR 512MB PC2700 HYPERX
AMD 3000 /333 ATHLON XP BARTON
CD rw was a Liteon cdrw/dvd swapped out for a liteon duel dvdrw

I set the jumpers for the dvd, hooked it up, closed the case and pushed the power button. Nothing showed on screen and the dvd kept trying to read and light flashed but no MSI screen or startup list. So I turned off the computer, disconnected the dvd and tried again. Same. Black screen. Took off each device one by one untill I was down to a bare Mobo and still nada.

I don't see how it could have been damaged but I guess its possible? I'm not sure what else it could be. I even tried hooking up another monitor just in case. Fans go on and network port lights up but thats about the only sign of life I have. The led on the power button even hates me.

Remove every thing then reinstall this items only:
1 piece of RAm
video card
CPU and fan

Disconnect all the front panel connections from motherboard as well.
Do this with motherboard off the case.
To power it on, short temporarily the two pins that normally connect to the power button until it start.
