Computer turns on and then right off

It makes a short beep but it turns on and then right off. It is a brand new computer custom built, i have checked the cables on the parts, what else can it be?

Take it out of the case and re-assemble it

Then test

[Waterloo9]

I have done that, a few times.

[mmettin]

What exactly have you done ?

have you cleared the bios ?

[Waterloo9]

The bios isn't even coming up it turns off before that.

[mmettin]

have you moved the jumper to clear the cmos ?

[Waterloo9]

Have tried that.

[mmettin]

Once again I'll ask, What troubleshooting steps have you done ?

please be specific

As of right now it is booting up and staying, i put the memory stick in the last slot and it worked.

Was just about to suggest that :P fixed my brother-in-laws custom build by shuffling memory. Once he set the timings and voltage right he could use all the slots again.
