Gateway MA2 Not Posting w/ No Indicators

I am working a Gateway MA2. When you power it on the power LED turns on at the power switch and the blue LED on the front edge powers on. The fan kicks in and it sounds like its starting up but it never posts. It just goes quiet and the only signs of life are the power LEDs.

Ive tried hooking to an external to see if it was posting and maybe the LCD was bad but no luck.

My initial instinct is the motherboard. Any better suggestions?
