built new computer but it won't turn on
Hi i'm new to this board.
I just built a new computer, all parts were new, and all tested to work.
It has a an ASUS A8N5X Socket 939 NVIDIA nForce4 ATX AMD Motherboard
XFX PVT42EUDE3 Geforce 6800XT 256MB GDDR3 PCI Express x16 Video Card
AMD Athlon 64 X2 4400+ Toledo 2.2GHz Socket 939 Processor Model
2 GB Memory
TV Tuner
500 Gb HD SATA
Antec Sonata Case with 450 w PSU.
I built everything, and hooked it up. When I press the power button a small zap noise comes from the PSU and then nothing happens. The green light turns on so the motherboard is getting power.
-I have built computers before and have never come across this problem.
*This is my 2nd motherboard and 2nd PSU (I thought they were the problem so returned them and got 2 new replacements but same thing is happening). I've tried everything and don't know what to do.
PLEASE HELP ME
