That's a very good guess, Roger.  It's good because it's the
same guess I had.   :-)
I did also change the power supply but forgot to list that with all the
other things that didn't work.
Thank you for the suggestion and the effort to reply.

None of those things had the slightest effect on suppressing freezing.
Only using a SATA 3 socket instead of SATA 2 stops the freezing.

That's got to be the weirdest fix I've ever discovered.

I write this to alert others who may experience freezes to try this
completely off-the-wall solution, and in hopes that I'm not alone
in the universe.

Chris, I agree.  Which is why the first thing I tried was to buy a
new different motherboard (to replace the almost new motherboard).
The two mobo's have onboard video that appears to be different, yet the
display during freeze is indistinguishable.

There's not much motivation to delve further into this problem because
the system seems stable, provided I use the SATA 3 socket.

I'm still interested in hearing of any similar experiences.
