Thanks guys. I might have found the issue.
Malwarebytes found a file, "RemoveWat.exe", to be Malware. The purpose of this program is to disable the Windows utility that detects your copy of the OS as non-genuine. I kept getting, "Please update to a genuine copy of Windows" and my desktop would reset, despite that I am using a legitimate copy. This program fixed the issue.
This very well may be the last thing I did before these problems popped up. Now I don't believe this program is technically "Malware" but it's possible some of the changes it does to get rid of WAT have in turn caused these issues.
My problem is if I do remove this (it has a remove and restore function built-in) I'll once again get that issue where it's detecting my genuine copy as non-genuine. Typing in the CD-Key has done nothing but delay the problem only for it to show up again a few days later. xD
My question is: Is there a way to fix that darn genuine bug without using this kind of program, which upon looking up just now, does seem to cause completely random problems...
