 Its over a day later and I have yet to experience another crash/reboot. This is the longest I have gone thus far without experiencing such, but I think it is too soon to tell. Maybe if after a couple of weeks of not experiencing such, I can say that something I did fixed this. If I get to that point, I may start one by one undoing the things that I most recently did, to see if undoing one brings back the 'crash/reboot' issue. .
