help! I have no video on shuttle sg45h7?

Can someone figure out my problem? I have no video output when I plug in my shuttle. Everything is new, I just finally got all the parts in to put it together. I'm trying to get onboard video to work. I rechecked the seating of the cpu and memory, I have 3 1gb sticks ddr2 memory, I tried all 1, 2, then 3 bays of memory, which holds up to 4 slots, 16 gb max (4 gb each). I dont have nor did i try an external card. HDMI also doesn't work. Its nothing to do with the bios; I can't even get that far. One would assume that onboard video should work right out of the box. I'm trying to stay away from assuming its doa. Any ideas?

Oh yeah, I forgot to add those details...
I have the correct socket type, which I double checked to see if it was seated correctly. It is compatible according to the specs of the motherboard. The heat sink and fan is double checked and properly seated also. When I hit the power button, the lights come on, the 2 fans come on, no video, no beep. The shuttle has bad user manual stuff, and says nothing about beeps or no beeps.

Possibilities include:
CPU not compatible with motherboard.
CPU not properly installed.
Heat sink / fan not properly installed.
Power supply not properly connected to both motherboard power connectors.
CMOS reset jumper in wrong position.
Bad power supply

It would help a lot if you describe the problem. For example, what does happen when you push the power button? Do the fans spin up? Does it beep?
