Strange issue With "Held" keys on Keyboard...

So this day just couldn't be better, I don't even know what's going on anymore, and apparently neither does my Google search world. The best way to describe what's somehow going on is this "Gggggggggggggg," key spam effect that happens when I simply press a key once. It started when I'm logging in to my desktop with my pin pretty much locking itself out after only pressing the first digit. And this isn't just a single sticky key no, this is what makes it weird. It's a selective spam key effect, as in all I need to do is press a key like once or twice (the response time here dropped dramatically, despite everything else running fine.) The key spam would correspond to the "desired," key pressed (eventually.) Troubleshooting the keyboard revealed the issue of "USB Composite Device is an older USB device and might not work with USB 3.0" error, recommending me to plug it into another port 2.0 or whatever. Only that doesn't fix the issue either. (Either that or magically all my USB ports became 3.0.) It makes even less sense when considering it worked all fine and dandy for I'd say nearly a year up until right now, (not to mention I apparently can't locate anyone selling "USB 3.0 keyboards," so doesn't that put me in between a rock and a hard place.) It's not like I have anything better to do anyway, but sit and stare at a screen I can't put input into now...
Seriously what is going on. What is this Ill begotten crap that I have to deal with.
