Onboard video problems

[billm1985_85]

I recently purchased a new system with a ASRock A780GMH mobo and I'm currently getting no onboard video response, it's just a black screen saying check signal. I've tried both DVI and VGA outputs to no success. I'm using a 21.5" Samsung LCD and it works fine on this computer. My specs are as follows:

AMD Phenom II X4 940 Deneb 3.0GHz
ASRock A780GMH
G.SKILL 4GB DDR2 1066
Antec EA650 650W PS

Any suggestions/tips on what I should do to get this thing up and running?

Clear the bios and try again.
