Thanks Philo for your comments on the memory chips.

Hi Kony:

I missed a sentence in the above effort. The Spire box indicates: "No risk
of damage to other components,"  "Reduces processor temperature," "Extends
processor life."
There was NO INFO whatever about a sleeve bearing or lubrication and the fan
is guaranteed for 5 years!!!!. What was I supposed to think?

After the fan cooled down I lubed it and it ran as it did previously but
that doesn't fix the rest of the box. Some damage was done and I am still
trying to find out where it is. Any suggestions for a diagnostic test?

The HD is currently in my old Intel box and I just completed the Win2K SP4
update. Now I have a question about returning this drive to the much newer
box that
gave the dxapi.sys error message shown above. Is it likely to accept it?  To
put the question in another way, if I install an OS on an HD, will another
box accept that HD or what changes need to be made to the software? -
boot.ini is easy. Are there any other changes to be made to a Win2K drive to
get it accepted in this newer box. I have a vague recollection that a drive
is initially formatted (anywhere) and then installed in the computer for
loading the OS. I'll have a try today.

Thanks for your great effort here and I understand your view on this. This
old box has been the most reliable by far that I have ever had. I could even
forget about the memory chips because they are much less important. I know
the issue of cost and my time but my major problem now is the newer box and
I guess I put too much emphasis on this old one.

Now I'll get back to the newer box and the issues of finding the problems
and restoring the hard drive. Will report on my effort soon.

Thanks again.
