Allan,
I worked on the same model last week with the same problem.
The processor has been overheated. This is a problem with the Compaq's
that has the Athlon processor. CPU cooling fan and heatsink get clogged up
with dust air flow drops processor temp climbs and eventually the processor
overheats and dies.
I swapped out the Processor with one I had salvaged from a system that
had a bad
motherboard, due to owner dropping a screwdriver on the board while it
was running.
New processor did the trick. System booted right up customer happy and
my pocket
book was happy.
Good Luck

Father-in-law called the other day, said his computer had popped up some
kind of warning about a fan. I advised him to turn it off and I'd try
to take a look at it.
I brought it home, opened the case, and blew out a fair amount of dust
with compressed air. Took it inside and it's exhibiting the following
symptoms:
- When connecting power cord, all fans (fan on CPU heat sink, power
supply fan, and another fan that exhausts the main case all come on at
full speed. Power light comes on, keyboard LEDs flash, but nothing on
the monitor.
- If I hold down the power switch, it turns off after a few seconds.
- If I turn it back on, same as above. All fans running, no other real
signs of life.
The fan on the back of the case is a bit noisy. I tried unplugging it
and nothing else changed. Ideas? Without any diagnostic message at all
on the monitor I'm at a bit of a loss. I'm guessing it's stuck in some
kind of "overheat, shut down except for fans" mode if such is possible.
Computer is a Compaq Presario SR2173WM, AMD Athlon processor.
