I was going to scoop a used HP EliteDesk Mini G3 to use as an HTPC playing files off of my NAS. I don't want to take any chances I'll probably just grab the Ryzen 2400GE one. Thanks again for the help fellas.
I went through almost the exact same thing as you with my 2600K. 4.8GHz for years and then all of sudden random restarts and crashes. The culprit was my PSU. However it seems you've changed yours recently. I still wouldn't rule out the PSU though.
