OK got it !

One screw and a pry handle, panel slides back, then out.

6 years worth of dust !

Relatively clean now.

Thanks all ...

Did you find the mouse that was getting its tail caught in the fan? :^)

Seriously, if you still get the noise on startup try and remember to briefly hold
one of the fan blades as you start up from cold and see if that stops the noise. Be
careful where you put your fingers in the process!

Take a listen. Not likely to be one of those bearings.

After being off over night, on start up my PC emits a sound for a
couple of seconds, and then works normally for the remainder of the
day. Sound is somewhat ominous.

Need someone knowledgeable to take a listen to the MP3 and make
recommendations and thanks.

Toward what end would someone be "harvesting Email addresses" ?

Mine is clearly shown as my username in postings.

Wish everyone would do that.

I chopped the very end off the recording and normalized it.
Just to bring up the level a little bit. Maybe I should
have companded it, and really cranked the level :-)

CPU fan speed is register controlled. If a Dell computer
crashes, the fan can be heard running like a hoover,
because then there is nothing to turn down the fan speed
after the power is applied.

The result is, when machines like a Dell start up, there
will be a second or two delay during POST where the
CPU fan speed hasn't been set yet. Once the POST
gets to that point, the CPU fan can be properly
adjusted for the amount of thermal present at
that point in time.

I'm guessing that's a fan noise, but it could just
as easily be a disk drive (judging by the "OK" sound
it makes nearer the end of the recording). It could be
that the fan stops rumbling on its bearings,
after the voltage applied via PWM is reduced a bit.

While you can peel the label back on some fans, and put
oil on the bearing, not all fans actually have an open
bearing. A Panaflo for example, you can't oil it because
the FDB bearing is sealed.

And if you add oil to a fan that takes oil, it attracts
dust, and can eventually cause problems again.

Regular non-FDB fans have ball bearings or sleeve bearings.
In particular, the sleeve bearings can lose their lubrication
in a very short time (one day). Ball bearing fans have 3dB more
noise, and because they cost a dollar more to make, are a
non-preferred type. However, when a company offers a decent
warranty, it doesn't pay to put sleeve bearing fans in the
machine, as the cost saving is swamped out by the expense
of shipping a machine to put a new fan in it. Or sending
someone to do it. Consequently, a Dell might get a ball bearing
fan instead.

Ball bearing motors get noisy as they get older. In
fact, a user is likely to replace the fan due to the
noise level, before it ever gets a chance to seize up
or something. I have disk drives with ball bearing
motors, that I can no longer sit next to, as they're
that loud. And the drive still works...

Replacing the main fan on a Dell can be difficult,
due to the five pin interface. Regular PC fans
come in two, three, or four pin varieties. But
Dell decided five was a nice round number, and the
first question I get is "what can I put in here?".
Well, there was a supplier of replacement hoovers
for Dell, but there's no guarantee they're still
in business.

If it's working now, you have nothing to worry about :-)
The above is just a backgrounder for you, for the
next time it happens.

Nice website. It works.
That's clearly a moving part, probably a fan. I'm
surprised it doesn't last longer.

For what it's worth, I use a technique to keep
the dust out that works well:

Go to Home Depot or Lowes. Buy one of
those big green air filters that's just a
plain gauzy pad and comes with a black plastic
grille. Get some plastic ties. Cut the pad and grille
into pieces to fit the areas of air intake holes.
Place each pad piece inside, cover it with a grille,
and pull through a few ties to keep the grille in
place. It's an easy, cheap way to keep the inside
clean.

.... Or if not a fan, maybe a loose case part?

Fans are cheap and basic. There shouldn't
be any reason that it can't be replaced with
a generic one of similar size. If it doesn't fit
one can drill new holes in the case or just but
machine screws with nuts to attach it.

Noise comes either : Shut Down - Power On ( or ) Sleep - Wake Up,
BUT only after an over night.

To me, it sounds for all the world, like something briefly coming
alive, then winding down for most of the sound. I think that rules out
fan bearings. System boots and works fine, and it doesn't sound like a
HD, so rule that out.

Also, the sound now comes every time after an over night, but I used
to hear it once in awhile very infrequently, since new.

I think it might be some sort of maintenance function. Could be coming
from the speaker (?); difficult to tell on a fly.

Did you try to post it on this newsgroup? This is a *text* newsgroup. A
decent newsserver won't show postings with binaries...

To me it sounds like your optical [CD/DVD] drive spinning up then down
Do you have a disc in the drive?

No dick in the drive, but it does sound like that and coming from
there.

I'll put a disk in and see if it changes.

SteveGG,

You can't put your dick in the drive!! It's impossible unless you have
a nano size. Dicks are designed to put in your mouth to blow it. It's
called blow-job. Did you try it?

I agree with Ron C, it could be the optical drive going out, bad bearing
or something. How about unplugging the computer, opening the case and
disconnecting the optical drive, then booting to see if there's any
difference. Plus with the case open and your head inside it you will
have more of an idea where the sound is coming from, if it's from a fan.
