HP making strange noise

My HP 780n is making a strange grinding noise (or rattling noise). If I
kick it gently the noise will go away for awhile. Am I having fan problems?
Should I open the case and try to refasten something? I appreciate any
suggestions.


Thanks,
Corse

The noise is most likely the bearing on one of the fans, clogged up with dirt.
Get a can of compressed air, unplug the system from the wall, open up the
chassis, blast everything clean with compressed air.

If the noisy fan is a processor cooling fan or a separately attached one, look
to replace it. If the noisy fan is inside the power supply, look to replace the
power supply. The noise is a sign of wear and tear. You do not want a system
fan to suddenly freeze up and stop spinning... Ben Myers

Hi,

Thanks. I opened the case up and the fan was, in fact, gunked up with dust.
I cleaned it out and now the machine, for the moment, is a lot quieter.

This is the sort of periodic maintenance to be done on a computer to keep it in
good working order. Next time, don't wait for the fan noise. Depending on how
dusty, dirty, full of tobacco smoke or full of pet hair it is where the computer
is, open up the chassis maybe as often as every 90 days.

If the processor fan starts making noise again, replace it. They are
inexpensive commodity items well worth the $US 10 or less to replace a fan with
failing bearings... Ben Myers

Ben,

I've had PCs since 1988 and this is the first one to have fan problems. I
appreciate your advice, however. By the way, where would I buy a
replacement fan? Does CompUSA or Frye's Electronics sell them?

Thanks,

Corse

You can find fans for around $10 a whack at a lot of mom 'n' pop
do-it-yourself computer shops. You probably have a no-name custom computer
assembler somewhere in your area that also dabbles in retailing components.
I have yet to see a major chain carry fans in my area. But having visited in
Fry's in the San Jose area, it is probably a good bet they have them stashed
away in an obscure isle.

Computer fans, just like everything else in the computer industry, are getting
cheaper and cheaper and more cheaply made. Certainly before the Pentium 4's
cooling fan monster, many CPU cooling fans are/were really ticky-tacky. The
designs of many name brand Pentium, Pentium II, Pentium Pro, and Pentium III
systems use larger and sturdier ventilating fans attached to the case and a BIG
heat sink attached to the processor. The larger fans are generally more
reliable.

If you're in the vicinity of Harvard MA (30 mi west of Boston), I can sell you a
new fan for $3 cash. You'll pay more in a store, but $10 would be about the
max... Ben Myers

Uh, there are no R's in the spelling of that city. Everything east of and
including Wustah replaces R's with H's.

It's H A H V A H D

(Preferably pronounced using that Thurston Howell III accent from the
Gilligan's Island television series.)

Nope. You've confused us with the World's Greatest University (that's WGU) in
Cambridge, MA. The founder of the university, John Harvard, moved 30 mi west,
and founded Harvard, MA. He did not bring the accent along with him in his
belongings. Most of us here speak the standard American dialect, the dialect
and accent most heard on ABC, NBC, CBS. Despite the prevalent mindset at WGU,
reinforced by members of the Kennedy family, ours is the prestige accent of
American English, just like the Oxonian dialect of British English and the
Florentine (properly written Fiorentine in Italian) dialect of Italian.

Can I get the fan and a new power source directly from HP? Where can I find
the part numbers?
