RESOLVED (Finally)
It wasn't heat related at all. I was careful to make sure the HS was installed properly and doing it's job. I'm somewhat anal in that dept because engineering is in my background ;-)
As directed by a kind member above, I downloaded Windows 10.
It fully installed and is up and running....not a hitch.
SO in the final analysis, new machines are not going to play well with older Operating Systems.
Thanks to everyone who took the time to help.
CASE CLOSED
