New Build: Problems please HELP!

I have recently purchased all my parts for my computer. I received it a few days ago. I put everything together. So i press the power button, I was suprise to find that it start it up (nothing was diaplayedon monitor) for a few seconds and just shutdown. All fans and light where on. So i decided to trouble shoot and take one peace out at the time to see what would happen. I took everything out and it still turn off. So i took out the CPU and that was the only time that it stayed on. The CPU was a little warm but even still i have a heat sink so i dont think it is that my CPU is over heating. I dont know what it could be, any ideas?

Motherboard:Asus P5ND2-SLI Socket 775 Motherboard
CPU:Intel P4 651 3.4Ghz HT 2M 800FSB Socket 775
Video Card:eVGA GeForce 7800 GT CO
Ram:Buffalo Select 1024MB PC4200 DDR2 533MHz
Power Supply:450w

You have a system that carries a pretty heavy load, I would say the a 450W PSU might be pushing it and could cause the shutdown. Who exactly made that unit? Whats the brand?

I tried that guide it still did the samething.This is a custom build unit. The PSU came with the case and its from what i read it is recomended for the video card and motherboard. That still doesnt explain why if you keep pressing the power button the time that it takes to shutdown varies.Do you think that i need to upgrade the power supply and to how much?

If it came with a case other than Antec, that PSU is garbage.

While I say that it is probably causing the problem, you can't really know for sure. If you have another PSU laying around, trying swaping that one in and see if the system starts
