A REVENANT PC?

A REVENANT PC?
Well, I started sorting out stuff in the Studio today, starting with the Studio PC. If you recall, this is the one that killed my graphic novel hard drive, and seemed to have done the same thing again. When I was trying to fix that I got into DISK MANAGEMENT and wrote down the serial numbers of the hard drives. This morning, examining that drive, I found that there were two sets of data cable sockets on the motherboard: a set of 4, and a set of 2. The problem hard drive was plugged into the set of two. So, I tried plugging it in to one of the two spare sockets on the set of 4.

PC booted fine, both to Win7 and to Min Linux; I was able to access the problem drives with no problems at all!!!

Has the issue been all this time that these hard drives were plugged into the wrong socket??!! I hate to admit it, but perhaps I've been a victim of lack of hardware knowledge. Most times when the PCs would play up I'd be struck with a panic attack. The times I fixed stuff I got past that and probably got a better understanding of how the hardware worked. Today I had NO expectations of anything to do with the PC. Hopefully today - after a library/shopping trip - it'll still work OK.

Which leads me to wonder what to do with the PC now. The Win7 install has been "damaged" and now considers itself to be NOT GENUINE. I did a bit of research before and it was probably due to me changing hardware. I'd moved the drive from an older PC into this one, and recently CLONED the OS partition to a larger drive. In any case I bought 3* copies on Win10 and have only used 2. But do I really want or need to have a 4th Win PC (the Black Box came with Win10 on it)??? I can always install that copy of Win10 on better hardware sometime in the future. Maybe I should just rip Windows out of the PC and reinstall it as a dedicated Linux PC, with apps that are only available on Linux.

Nothing I need decide right now. Suggestions please.
