I just upgraded my mobo and when i turn on my computer there's no video. I don't think the hard drive is running either. please help!

Please list your full system specs.

First, the stupid questions

-Did you plug in both the 20/24pin AND the 12vATX power connectors to your motherboard?
-Does your graphics card need its own power connector?
-Is your ram compatible with your motherboard?

Please tell us EXACTLY what happens when you push the power on button. Anything happen? Fans spin? Lights?

When the system is not turned on, are there any LED lights lit up on the motherboard?

Did you disable the onboard video or did you connect the monitor into the wrong port (onboard or card)

Well, I tripple checked my system compatibility and my mobo doesn't support dual-core processors. So i guess I'll go buy a new mobo.
Thanks guys
