Installing the backup drive I made when I built the machine has fixed the problem, and also ruled out all the things you suggested in post #4.
I would not run my normal PC without it being fully updated and with updated security software, but the usage of this PC does not warrant it. In fact many doing the same thing, actively discourage it, often using stripped down versions of the OS.
I'm really sorry to keep pushing this point, but problem solving and fixing PC does not solely rely on performing updates.
