Alright as I said this is me building this from just the parts so it is of course possible that I messed up. Although I have redone this around half a dozen times so if I'm messing up im in real trouble. But anyway what happens is hit the power button and absolutly nothing happens. I do have it plugged in, and also I notice when I hit the I/O button on the power supply turning it on, the keyboard that is plugged in Cap/Number lock buttons will flash a few times. Other then that nothing happens. Alright I understand that this probly is not really a ton to work with, but any suggestions/ideas would be welcome. Thanks, Riley.
