Hello John,
Try this simple check, do what's called a "naked boot", using just your video card hooked to your monitor, and of coarse your atx, no cards, nothing else, no drives, HDD, cd's, snd cards, network, nothing, if it'll post into bios, then add on one card or any other component at a time, this will tell you what's causing your board not to go into post, is this does not work, MB is at fault.
