The main cause, as explained, is the battery (CR2032).
You need to change it.
It causes also BSOD.

The OP did mention that he tested the CMOS battery and it read above
3.0VDC.

Now it could be the battery holder that is defective. You need to
check that Vbb is getting to the timekeeper - and someone kindly
posted a ink to the schematics so the OP can check that out now more
easily.

Hi John,

I was testing the battery voltage where the battery holder's terminals
are soldered to the board.

Now that I have the schematic, it should be fairly simple (famous last
words, right?) to track down the fault.

Thanks for your reply.

Nothing better than fixing stuff IMHO.

We generate enough garbage that keeping something going that is still
useful is worth the effort, puls the brain cells need exercise!

I cosign on salvaging electronics and exercising the brain cells.

By the way, how is it the computer keeps perfect time once the time is
set and the power remains on? Shouldn't the time shown in the BIOS setup
screen begin to advance too once it's powered on?
