New computer not booting at all

I just built my first machine with parts I ordered through newegg. AMD
Athlon 64 X2 4200+ CPU, Asus M2N-SLI Deluxe mobo, 2 GB of G-Skill DDR2
800 MHz, Soundblaster Audigy2, one Western Digital Raptor 10k RPM 36 GB
SATA, one Western Digital Caviar 320 GB SATA, a Lite-On DVD burner, and
a brand spanking new XFX GeForce 8800 GTS card, all running off of an
Apevia 680W PSU in a Lian-Li case.
The problem goes as follows:
Hit power button
Lights go on, fans start going (except video card) including LED power
indicator on mobo
Power goes off, the end

Here's what I have tried so far:
-Re-re-re-re-re-checking the power, reset, LED plugs onto mobo
-removing every last non-essential power-consuming part (stripped down
to one GB stick, and video card)
-Now I know this isn't smart but since I've done it, the same condition
remains...but I hit that voltage switch on the back of the PSU up to
230V. What it did was it actually powered everything (video card
included) but I wasn't getting a signal through my LCD monitor (using
DVI-to-VGA adapter unfortunately).
I fear that didn't do any damage, but it's still doing what it was.
-switching PCI-E power cables
-using the reset switch as the power switch (not a faulty switch, and
is at proper polarity)

That's about all I can think to do. I know one of the parts isn't doing
it's job. Not sure if I should get a higher wattage PSU, or get an RMA
on the video card, both RAM sticks or what.

Heat doesn't seem to be an issue at all, nothing's over heating so I
know it's not the auto-shutdown feature of an overheating CPU.

I'm stumped, HELP! Very anxious to get this thing going!

have you tried to use the cpu in another motherboard

Try it without the video card and see if it gets any further.

How do you know its not overheating? Presumably it powers off before
you get into BIOS to check results of any sensor.

Overheating caused by heatsink being in wrong position or not seated
correctly can have an instantaneous affect.

I did try it without the video card and a get a loud beeping noise and
am unable to turn the power off using the switch, I have to hit the
PSU's power switch to turn it off.

I have not tried this, I only have one AM2 mobo on hand and that's the
new one.

I suppose that I'm not 100% sure, but I did re-seat the CPU and
heatsink. Didn't smell like anything burning up, and the thermal paste
did look a bit splotchy.

I assume that beep is the no video warning. So since it doesn't just
shut itself off immediately like before, that narrows it down to the
video card or the PSU.

I assume you did plug one of the PSU leads into the GTS 8800? If you
did then you might try other leads. That PSU has dual 12v rails, so you
might try to find one on the other rail (The Enermax PSU I have on my
Athlon64 system has a different colored molex connector made
specifically for a video card.) You would think that the PSU you have
can handle that card based on the specs, unlike a lot of cheaper PSUs
which have single 12v rails and wattage ratings inflated by the 5v
rail's amp rating. I don't know anything about that brand, though.

If you are sure the card's power supply connection is correct then you
should try a different video card and/or PSU.

Okay guys I figured out the problem. The PSU manual didn't say anything
about the 4/8 pin ATX power connector that you can split in half. Once
I plugged that mofo into the ATX12v plug next to the CPU, it booted up
without a hitch. Thanks for the responses!
