Unhook everything and only hook up the power button from the face plate. Push the on button and you should see the fans start to spin, and quit. If the fans spin a little bit, then start adding everything back in, and push the power button every now and then to make sure it's still working. If not, then double check the connector from the PSU to the MOBO. I usually find its easier to "wiggle" it in back and forth than it is to just push it straight in. If you are sure that connection is good, then start making sure you plugged in the power button to the correct spot on the MOBO. You may have to refer to your mobo manual to know for sure, but it's unlikely you will damage anything by trying it different ways.
