Dang thing wont start

[Trooper4985]

I just put together everything I got for christmas and it wont start. I've built it twice today thinking I did something wrong so I took it all apart and started over from scratch... still nothing. The standby light on the motherboard (A8N-SLI premium) is on but it wont fire up when I hit the power button. I've even tried a button from a diffrent case thinking maybe the switch was bad.

Please help.

did you forget to connect the 4-pin molex power connector to the motherboard? (in addition to the big 20-pin connector.)

The molex (EZ-Plug) or the 4 pin plug on top of the CPU slot?

Reseat those cables. If that doesn't work, build it outside of it's case on a surface that is non-conductive. It's possible the board is grounding to the case. Also, check the PSU. Make sure it's actually supplying power (ie. it's on, plugged in, working, etc).
