  1. Sounds like a bad power supply. Also check that everything is plugged into the mobo correctly. Could be a bad power button from the header. If you unplug the main power feed to the mobo, you can use a jumper wire to turn on your power supply and make sure it is working. I believe it's green to black but not sure. A quick search of this site should tell you. Good luck.
  2. The brand new power supply was dead.. I took one out of another pc and it worked.. Hey, what did I expect for $120? something that actually worked? Thanks for the help! (system is awesome!)
