First time build, won't start at all

[Juken]

First time poster, first time build, the things I have are:

Thermaltake Tsunami Case

ECS NFORCE 570 SLIT-A (V5.1) Socket T (LGA 775) NVIDIA nForce 570 SLI ATX Intel Motherboard

Thermaltake purepower 500w

Intel core 2 duo e6400

I'm guessing those are the necessary items just to see if everything works, I tested the power supply and works perfectly - all fans turn on even the cpu fan, but when I try to turn the computer on with it connected to the motherboard, nothing, no lights or fans. I've checked everything, the 24 pin power connector, the 4 pin, and the jumpers, nothing turns on. Did I put the power jumpers in the wrong place? If you all need more info, let me know thanks.

Any beeps? Also what is your graphics card and RAM. These are most definetly needed. Though I think the mobo should beep a no ram code if you don't have any RAM or its defective. Also, are you sure you installed EVERYTHING correctly? A more complete list of parts would be the first thing needed in order for use to determine this.
