Update on the Desktop saga. I finally got Windows 10 to install on it, however yep, something is definitely fucked. now it's repeatedly freezing or powering off after being booted and logged in, pretty quickly, too. Maybe 30 seconds to 2 minutes after booting. Once it even booted into startup recovery.
@Bri No no no no, that is Windows charm. Now you have to trouble shoot that. Once you figure it out, soemthing else will show up randomly, just for you to trouble shoot that too. I want to bill Microsoft for all the hours I have wasted.
