It is also possible for a computer case to resonate at a frequency
excited by a hard drive. Some drives vibrate from side to side, and
a cheap case can amplify the sound. At 7200RPM (120 RPS), you'd
expect the sound to be like an "AC hum". This is one reason I like
to purchase heavy steel computer cases, to help damp out that kind of
noise.

I would not "whack" the computer case, because if you do, sooner or
later you'll have a data recovery problem on your hands, when the
disk is damaged. The disk might be innocent.


Thanks Paul--very helpful. From your post I conclude it's likely
either a fan for the CPU or graphics card (since the sound dies out
*after* the AC power is off, as the fan blades are winding down "tick
tick tick" they make a last few dying sounds.

Likely the HD is not the culprit but it being 5 years old I'm
replacing it as a precaution.

Banging will not bother anything IMO (I don't bang hard).

I installed "Motherboard Monitor 5" utility and the CPU temp for a
Northwood series 120nm Pentium IV is 102-111F (or 39C to 44C) at idle
to light overhead, which from what I can tell here:
http://www.digit-life.com/articles2/p4-throttling/index.html is
normal

Any other tips appreciated; thank you!
