recently, I amhearing a bzzing sound coming from my tower unit.
Sopmetimes, it's only for a very short time but sometimes it is a bit
longer.

What do you think is acting up?

Could be a fan buzzing (?).
Get the cover off, and have a close listen.

We get this a lot in our shop. You'll want to call an exterminator over,
as there is a beehive inside of your box.

Let's see - it could be anything simple like a fly trapped in your box to
something drastic like the power supply arcing, in which case you'd probably
smell something too. Other than that, loose screw, fan bearing, etc. Take
the cover off and keep listening and try to isolate where it's coming from.
Or you could play loud music and ignore the buzzing. :)

I have *actually* seen a live wasps nest attached to a video card,
inside one computer. I wish i had taken pictures.

Anyway: buzzing can be anything from fans, to cds, to floppies, or
even the power supply or hard drive. To pinpoint it, you'll have to
open up the tower and do some detective work.

Another suggestion: If it is a very quiet, but annoying buzz, then it could
be caused by your USB mouse? My MS Intellimouse Optical causes my PC to buzz
very quietly when plugged into USB, but everything is silent when on PS/2 !

Can you describe the buzz in a more helpful way?

A fan -- most likely. I can think of two scenarios off hand:

1. If a loose wire or some other debris pops into the blades, it's
like having a card in the spokes of a bicycle, until it bounces back
out. Of course, if it found its way in there, it'll find its way back
in. Adding a grill will reduce the problem. This happens a lot more
with the CPU fan, as most people have already have grills on the case
and PSU fans.

2. If the bearing on a fan is starting to go, you might get that
noise too, and it'll be intermittent. It can be a buzzing or a high
pitched warbling or squeaking. As the bearing starts to wear out,
the fan gets unbalanced, causing the noise. It's intermittent,
because it'll sometimes kick back into alignment, and then bounce back
again. Oiling the fan can help temporarily, but really the only
option is to replace the fan. Good luck tracking down which fan
though, as a modern machine can have several fans. In my own
experience, it seems that the larger fans (case, PSU, CPU) are more
likely to be the culprit, as they'll make more noise and be more
noticeable, but it could be any of them.
 
I would say, if it's only internittent then it would seem as if you
have a fan that's ready to go
