One of my boxes started screeching, for all the world as if a fan

Curiously when I moved a running USB drive the noise stopped.

When it started again and moving the same drive (and another connected
E-SATA one) had no effect I reasoned that my first guess was right and
it was a fan.

I got half way through moving the boxes out from under my desk and
taking the sides off etc. to track down the source when someone called
at the door.

When I went to the door I discovered the noise was actually someone a
few doors down the lane drilling into his wall.

And the moral of this story is: always look for the easy solution
first . . .

About 40 years ago my motorbike spluttered to a standstill after about 300
yds. I was taking out the plug when I noticed that the petrol tap was still
off!
Ever since then I've approached faults on the basis of "always check the
fuel before stripping the engine". It's saved me loadsawork manyatime!

hehe, BTDT with an old VW Beetle which had a fuel shutoff tap

A friend had an ongoing problem with an Escort which would suddenly
stop, but noone could ever find a fault with it.

Over time he replaced the distributor and all the electrics, the
carburettor and in desperation put in an exchange engine.

Eventually the fault turned out to be a jammed thermostatic flap which
directed hot air from the manifold into the carb when it was cold but
was supposed to switch to external air when the engine warmed up.
Overheating the carb evaporated the petrol and by the time the
breakdown guy/fitter came out it had cooled down again.

My first step in computer fettling is usually to pull all the cables
and replug them, then do the same with the cards. Easy and cheap and
you only need progress to more complicated things if that fails to fix
it.

The bruise on my head from crawling under the desk is healing nicely
now, thank you <G>
