Asus mobo problems

I'm asking for a friend, who have his Asus P4P800x mobo busted. The PC
wouldn't turn on when you press the power button, where the power supply
is fine (one indication of this is the connected optical mouse would lit
if moved).

Previously, he has similar problem, also with the same brand and model.
The vendor says that the culprit is a burnt IC on the mobo, and replace
it with a new one, which now have the same problem symptoms.

The question is what can cause this problems? Should he replace his mobo
with a different model? Is P4P800x a bad model?

PS: If it have to do with power line problems, then when why his other PC
(4 of them, using different brands like Micron) are not affected?

The setup are: P4P800x mobo, SoundBlaster Live! 5.1, Innovision GeForce
MX2 400.

TIA
 
My ASUS P4S8X-X seemed to exhibit the same problem. The hints from BIOS
beep codes (which ASUS seems to keep Ultra secret or AWARD simply never
tells them) seemed to indicate an undervolt in the +3.3v supply. Whenever
the CPU was taxed by an application or game during intense periods, the BIOS
beep when sustained sounded like a Hee-Haw that repeated. I was told by one
website that this was a thermal problem code. Reviewing temps showed
nominal temps and fan speed. Running ASUS probe revealed that these beeps
showed up only when there was that undervolt. I was thinking it may have
been the power supply, but your problem seems to be a little too similiar to
mine. I am awaiting a reply from ASUS technical support. I believe my
board it may have killed my previous CPU as now it may have killed my new
CPU.

Did your friend's CPU die in the process?

Nope, the CPU is fine. The vendor agreed to replace the mobo w/ the same
model (P4P800X) and the power supply. It is yet to be seen whether this
solves the problem. My question still stands though.

By an +3.3V supply undervolt I'm assuming the supply cable to the mobo (the
wide one), am I correct? And that killed your CPU. In my friend's case,
it's the ICH5 chip. It's been confirmed by the vendor that the 2nd case is
similar to the 1st case, busted ICH5. A problem ocuring 2 times in a row
indicates there is something very wrong, whether in ASUS mobo design for X-
series, or elsewhere, but which?
