Sorry, I did not have this issue. You are having a much more basic problem that really doesn't have anything to do with building a hackintosh.
I believe you are having a hardware issue somewhere. One of your components is probably causing an issue where the motherboard can not start. I would suggest pulling out nearly everything (Graphic card, all hard drives from SATA, etc). Basically, just the motherboard, CPU, and 1 stick of RAM should be plugged in. If it POSTs, plug in the rest of the RAM, if it POSTs, plug in the graphic card, and so on until you find the piece of hardware that is causing your problem.
