Restart after overheating Robert 02-06-06

Hello! I hope you can help me.

Last weekend I put together my new computer with water cooling using the
Zalman Reserator 1 Plus. I use it to cool the CPU, VGA and Northbridge.

Everything worked fine, however the next morning my girlfriend switched on
the computer without starting the watercooling!
After 20 minutes or so the computer switched off automatically. Probably due
to overheating I guess.

After that I am unable to switch on the computer again (after it has
been cooled
down). Nothing happens as if no electricity is present. The led on the
motherboard
is glowing to signal that the motherboard is having power to switch on.
However pressing the (soft-on) power switch has no effect. The power
supply is
functioning fine in my old system.

My guess is that something is broken now in the motherboard.
But how to know for sure? Or is nothing broken yet and I need to 'tell' the
motherboard that it is safe again to power up? I tried clearing the
CMOS, but
that did nothing.

Okay I hope someone can tell me the magic solution or tell me with some
confidence that I need to buy a new motherboard.

Hardware specification:
Asus A8N-E (Nforce4)
AMD64 X2 3800+ (CoolNQuiet enabled)
NVidia 6800 GT

Maybe the CPU was fried.
Try to test the CPU in another PC or take it to a computer shop to ask
them to test it. You might need to pay a small labour fee to test your
CPU.

But isn't a motherboard supposed to power up even without a CPU?

You are joking right?
Can a human still alive if the brain is death?

Maybe I was not clear enough.
Of course I don't expect it to boot up windows. But I would expect for
the power to turn on, spin up my harddisks, and make soms beeps on the
speaks or audio to signal that the CPU is missing.
Something like this:
http://www.bioscentral.com/beepcodes/awardbeep.htm
Beeps: Repeating High/Low
Description: Either the CPU is not seated properly or the CPU is damaged.
