i just replaced the motherboard and hooked everything back up only to find that nothing is working still which is driving me nuts. any other idea's what issue might be?

screen stays black as if unplugged and vga port does not work on either tv's i have or a pc monitor.

i assume the graph card on an inspirion 700m is on the motherboard which i just replaced so what next?
