I think this can easily be the CMOS battery. It is common for the CMOS
battery to go bad and cause minimal/subtle problems, although I expect the
main symptom will often (not always) be the the computer's clock losing
time while the computer is off. CMOS usually "freezes" without actually
forgetting anything when the CMOS battery voltage goes low, especially if
low but not zero.
Furthermore, if CMOS actually forgets things, you usually don't have
fatal errors if the computer ends up or defaults to auto-detecting drives
and any other hardware where it can forget any required settings other
than specific "usual" ones that a fair amount of hardware has.

If the clock does not lose time if the computer has been off a couple to
a few days, then more likely you have a motherboard problem other than the
CMOS battery. Second suspect of mine is the BIOS IC - to a little extent,
a replaceable item, although you may have to go to a few computer shows
with some vendors with older stuff to get a replacement if this is more
than a few years old.

Please consider that a lower end new computer nowadays only costs a few
hundred dollars (including RAM and a hard drive) and will outperform the
best available 8 or so years ago for 10x the price!
