How about I reset to Windows 8/8.1 for a day or two, and install nothing else, and see what happens then? I don't mind spending a day or two on each step that's fine.
Best to take your cues only from jpwise from here forwards. The manufacturer service technician is the best person to take you all the way through to resolution by following the mandated process.
There is some time lost so far on your own initiative, but now you are in the right hands to take it forward to resolution.
Alright. He suggested I reset to windows 8, so I will do that, and wait a couple of days.
