I was about to say the same thing - power supply.
I have a little Shuttle PC with a 200w power supply that seems to automatically reboot if I'm stressing it out too much. I did some research and I heard this can happen with power supplies like this - so maybe yours is just bad. From what you are saying, the common thread seems to be that you can't get full power out of the thing.
I might be wrong, but then again it's the cheapest option when compared to the others. I would get a beefy power supply if you are putting it under as much stress as you say you are.
Good Luck...

Is it possible that you have a bad power supply? Or one that doesn't
provide enough A at one of the voltages

I'm looking to tap into the wisdom of WPLUG for advice in minimizing the
financial cost of fixing my desktop computer, which crashes frequently
(MTBF ~36 hours) under heavy CPU load. I'm running Debian testing,
2.6.11-k7 on an Athlon XP 2000+ and an Asus A7N-266 mb.
There are three types of crashes.
One, if I set my motherboard's jumpers properly (i.e. my 2000+ runs at
1667 MHz) then the computer is guaranteed to crash within five minutes
of
boot. The computer only runs at its reduced clockspeed of 1250MHz.
Two, if I run 'lame' on about 30 minutes of audio, there's a 90% chance
that the computer will crash (behavior: spontaneously powers down).
This
also happens in certain other situations with high CPU load.
Three, sometimes the computer will randomly lock up -- screen freezes,
mouse / keyboard unresponsive, sshd doesn't answer connection requests.
After considering the situation, there are four different possibilities
that I think are likely. Any one will cost about $80-100 to fix, so I'd
like to get it right.
a. Temperature. I have lm-sensors installed; mobo temperature is
40-43C and CPU temperature is 49-51C in the steady state. These don't
seem to be abnormally high... fix is to buy a better case+heat sink.
b. Faulty processor needs replaced (because of the 'type 1 crash')
c. Faulty motherboard needs replaced (alternative diagnosis of 'b')
d. It's possible that the 'type 3 crashes' are caused by a bad video
card.
I haven't really considered the memory because the problem has not
always
occurred (though I can't remember when it started occurring). But I'll
install and run memtest86+ while I wait for list responses to trickle
in.
I built the box myself with parts (presumed new) from a discount on-line
parts house. The Video Card is from eBay.
The case has really awful cooling, which is why I thought temperature
might be the culprit. I'm also running a cheap aluminum heat-sink
instead
of a copper one. It's seated so tight that I couldn't get it off the
processor to check the conductive paste (which I applied when I
installed
the heatsink). I would have to probably take the whole thing apart in
order to be able to get at the heatsink to remove it.
If i were better off, I'd just buy a new Asus board, new processor, new
case, and new heat sink, but I won't be able to swing that. As it is, I
am in a constant state of panic that my computer will shut down.
Any advice?
