So it's only a single beep at a time or only a few but not
immediately repetitious?
If so, it's probably a windows generated error and windows
is then beeping the speaker. Try to isolate what is
running, run scandisk and SFC (system file checker), though
it can be a bit difficult to weed through what are and
aren't valid newer files unless you had made a newer file
signature file, so it's hard to know what is ok or where to
get some of the files after so much time has passed (unless
you are regularly dealing with these systems and remember
all these old '98 issues?).

Try another scanner or two, I had an old box that hadn't
even been turning on for months, was just sitting around
after someone had abandoned it into my care, and it only
found viri after the antivirus was updated.

Leave the system sitting in the bios menus or boot to DOS
and leave it sitting to see if the beeping starts. I
suspect it is due to windows. Has anything at all changed
on this system recently? Keep in mind it could have
happened earlier but until Win9 had rebooted, applicable
changes might not have been made that caused this.

I'd grab a spare floppy drive to test that, it could be the
problem.

I doubt it, unless system was so instable as to be causing
errors but you make no mention of other problems which
should be evident too.

You might look into sealing off most of the case holes
except a primary intake path and put a filter over that.
The filter will of course have to be cleaned periodically
but that could be easier. Sometimes it's hard to put a
filter on but one lazy way is to just take off the bezel,
drill a few holes and put in steel bolts. I mean use the
bolts as magnetic attachment points, you can then put a
filter panel on an area and magnets on the other side of the
filter opposite where you placed the bolts, so filter panel
comes off simply by pulling magnets off. I don't know how
much airflow these systems need though, or how much
accesssibility - sometimes they can be put in a cabinet with
a filter on that and an exhaust fan in the back, instead.

Ram does not generally fail like this, it would be far more
likely the slot contacts were fouled with dust/grime or the
motherboard itself had degraded - which could cause memory
to fail I suppose but generally the board would become so
instable the system wouldn't run at all first. You can
check the memory with memtest6+, but I doubt that's the
problem (though you could have memory errors too, in
addition to whatever is causing the beeping, or memory
errors could cause the beeping but the modules themselves
are physically ok, rather it's only an instabilty caused my
the motherboard or PSU).

If you need to rely on these systems it would be good to go
ahead and replace the batteries, they are old enough now
that their expected lifespan is up... regardless of whether
they're causing the beeping or not.
