Hey all.
So, after poking around in BIOS trying this that and the other thing to clear these errors, I finally did something that I couldn't fix and broke my 'puter Sunday, which.. required me to take it in for repair. While there, I explained the crash issues we have all been experiencing and.. he fixed it for me.
Turns out, Using the XBox app to d/l to PC is the culprit. We downloaded via Steam and, voila, problem solved.
BTW, most modern CPU's have AVX on by default with no option to turn on/off. (Per my new friend the IT guy)
