I tried the solution noted above (run task manager, file, msconfig, stop the two offending processes). It worked correctly. System now starts up and does not have the screen flashing.
I dredged up this web site while on the phone with Microsoft but they could not figure it out. Their answer was to put a $1400 hold on my credit card and replace the system. Mind you, this surface 3 pro system definitely has defects. It does not have the factory recovery procedures that you should have when you do the SHIFT-Restart (I get the Advanced option, but there is no option to restore to factory. There is only EUFI and Startup Settings. But at least now I can take an image of the Surface and continue to use it.
I would not feel so compelled to whine a bit, but this is a vanilla Surface 3 Pro. I've applied the Microsoft updates, moving from Windows 8 to Windows 8.1 and have installed Microsoft Office Pro 2013 on it. THAT'S IT. I expect a better upgrade than this mess. BTW: the tech did say to not do the upgrade to windows 10 by using the Microsoft icon in the system tray. The advice was to go to a Microsoft "site" and download it from there. I find that very curious!
