I just built my first rig with the ASRock P67 EXTREME4 and it booted up first try, so unless you have a bad board it's a problem with the other parts.
Have you checked to see what the minimum powersupply wattage is on all your parts especially the graphics. I see you have a 430W thats a bit low most mid-rang cards normally need at least a 500W psu, so this could be your problem.
