Not to worry. It will likely return :-;

Just as a remote possibility, have you changed resolutions, or refresh
rate on your monitor?

Good question. I recall trying to change, unsuccessfully. Hmmmmm.

Classic indication of a bad ground, or a ground loop.

I haven't changed anything.
And the problem hasn't gone away either.

Well, I did change something, as I finally recall now (as prompted by M.
Coso's post). I did put a new (used) monitor on that computer about 10-14
days ago. Maybe it had some affect. Dunno. I guess I could always try the
original one. Tomorrow.

Hi OM,

It could (and that would be a good check), but my guess is a change of
weather will make more difference. If so, we go into the third chorus
of
Classic indication of a bad ground, or a ground loop.

A bad ground will stay with you for a very long time. A ground loop
can come or go with the same appearance of:
love,
superstition,
the deal of a poker hand,
or a political forecast.

Quite possibly there is some sort of grounding issue. I only bring up
the monitor possibility because I have seen the way some monitors, and
the circuitry that runs them, can really sing when a change is made.
What adds spice to the problem is how Windoze will sometimes change
resolutions on ya. Happens a lot more in DOS, but if a person is a gamer
- or a Ham who still uses DOS - it can come into play more often than we
might think.

My interest is piqued! Mr Watson - don't you dare solve this problem
and not let us know what the cause was!!!! 8^)

Hi, I plan to let everyone know. It has garnered a lot of interest.

The problem went away about 5 days or more ago. I reported on it. As several
have predicted when I posted that, it's back!!! Interesting timing. I sent
the C. Crane device back about the same time it returned.

I haven't been able to switch the old monitor back in, but in view of the
return of the noise, I guess that's unnecessary. My shoulder is real cranky,
so I haven't been able to make the swap.

Someone is sending me a corcom filter, but I haven't received it yet. I
tried getting a tripplite outlet. I should have bought one while I was at
HSC in Sacramento last week. They had several multi-outlet filters. Jameco
and Digi-Key struck out. It's too far from here to jog down there.

The story continues. Stay tuned.

And now it has stopped. What strangeness.
