Popping sound on shutdown.

When I shut down my computer, I get a loud popping sound through the
speakers. It's a decending frequency, as if it's coming off a
spinning disk as it slows down, starting at maybe 1/4 second intervals
and slowing 'till it stops over a period of five seconds or so. I
don't know what hardware info would be helpful in the diagnosis. It's
a Maxtor HDD, about 11/2 years old, Klipsch speakers, Asus P4B266
MOBO... The system seems to be running well, no SMART warnings or
anything, it's just annoying and mysterious. I did Ghost the drive
just in case but would appreciate any ideas as to the cause.

Thanks very much in advance.

Disconnect items, power up, power down... See if you can determine what it
is.
 
The flux capacitor. or decombobulator.
J/K.
I heard this similar on a pc running on a two wire outlet, without a ups.
It went crazy every spring...with strange noises upon off and on.
Anyway.
Strange "ground return" is my guess (I did not know what to call it then,
nor now. Call me anything but weird.. the ground can't be live from the
other direction, such as outlet.) Maybe more or less than 60hz going on
there (obviously)

It could be the PSU is not turning off cleanly. Don't ask my how you
are supposed to fix it. Sometimes not even swapping power supplies
helps (if the problem was the driver used on PS_ON# on the
motherboard).
