Real hardware problem this time - computer won't boot

This is not my week when it comes to computers! Argh!

Anyway, my old ECS mobo crapped out for the second time, so I said,
screw this, I'm going with Asus. I bought an Asus A7V8X-X and a stick
of 512MB DDR-RAM, 333Mhz FSB, PC2700. I tried assembling my new
computer, and to put it simply, it doesn't work. As soon as I flip the
power switch (not the circular button on the front of the case, I'm
talking about the 1/0 button on the ATX power supply), the system hums
into action, the fans all turn on, and things start happening. Then, a
few seconds later, the power just abruptly cuts off.

Here are the full hardware specs in case it helps any:
450W ATX PS
2100+ Athlon CPU
512MB PC2700 333Mhz FSB DDR-RAM
Iomega internal 4x/2.4x DVD+RW drive
floppy drive
40GB 5400 HD
56X CD-ROM drive
Radeon 9000 Pro videocard

I tried to keep as many things constant as possible while switching out
the mobo. The only changes I made besides the RAM was plugging in the
speaker/IDE LED/power switch, etc. indicator lights & switches. I
tried, to the best of my ability, to put them in correctly according to
the manual. I don't think that them being in the wrong slots would keep
the whole system from booting - it would just stop those lights from
working, right?

Anyway, I tried taking out all of these little wires except for the
power switch. Still a no-go. Upon flipping the ATX power switch, the
whole system turns ON, which is unusual, because previously this
computer required the switch on the front to be pressed before it
actually turned ON. Could this be the cause of the problem - and anyone
know how to fix it? Thanks in advance for the help.

By disconnecting all the drives and front-panel LEDs/switches, I can now
get the computer to stay on indefintely, so I suppose whatever was
causing the short is now fixed. However, I'm having a different
problem: it doesn't ever send anything to the monitor. I guess I'll
have to plug the speaker in to see if it POSTs.
