the fan on my power supply isn't working, and the machine (Pavilion) shuts
down when it gets hot.

where can I buy a new power supply - I cannot find any on the hp website?

Brian,

3rd party parts houses pick up the slack when the name-brand manufacturer no
longer stocks spare parts (and maybe never did for Pavilions!), but they usually
charge pretty outrageous sums of money.

eBay is really not a bad source for parts, assuming you can identify with
absolute certainty the power supply you have and that the seller has an exact
match.

Unfortunately, many Pavilions, including yours, have a not very standard 3-wire
lead from the power supply to the motherboard. This lead provides thermostatic
control for the power supply fan. This also means that you would have
difficulty using a non-HP standard ATX-12v power supply. Pavilion power supply
form factors are also different than the bulky ATX standard. Other name brands
use power supplies of the same dimensions and wattage, but you have to make sure
that the 3-wire fan control lead is on the replacement power supply.

Although I do not recommend repairing a power supply by replacing the fan, this
is a course of action I took a couple of weeks ago when a client's Compaq
Presario had a seized power supply fan. This Presario (UGLY computer!) uses a
power supply that cost over $100 on the open market, and the client needed the
system back quickly. I found a matching fan in my parts bucket, opened up the
power supply, snipped off the old fan's wire leads VERY close to the fan itself,
replaced the fan, soldering the wire leads together, taping with electrical
tape, and securing the soldered wires with some plastic cable ties.

I rarely solder anything on a computer system, but once in a while duty calls.

Expensive for what it is, but less expensive than I might have expected.
