This is my last post on this thread because I solved my problem.
Through 3 months of working the problem doing troubleshooting and OS installs, including a "Clean Install" which did not help. I narrowed the problem down to Windows 10 having a random bug when using 2 Graphic Cards and a specific Motherboard. I say random because it affects different machines differently, depending on the Motherboard. On my particular MOBO (ASUS Z87 Deluxe/Quad) W10 could not handle 2 graphic cards and 4 Monitors. I had Microcenter run a verification check on this. I said depending on the MOBO because I have an older machine with an ASUS (P5N32-E SLI), also with 2 graphic cards and it runs the exact same OS with no problems.
Once it was verified, the only solution left, albeit an expensive one, was to go to a single graphic card that could handle 4 monitors (ZOTAC GTX 1060).
The machine has been running day and night, stable since.
This speaks loudly about the quality of the microsoft releases. The company has not changed. They just changed tactics when they decided to copy all the capabilities of Apple OS; but kept their Strategy, of using their user base as Ginny pigs for "improvements." Why should they pay their programmers for extensive testing if they can have us do it?
