Just a quick question, is it your computer that’s playing up or the operating system?
Even if you have absolutely no intention of ever trying Linux I’d advise you to download a copy. Linux distributions operate as a Live Desktop running from a USB thumbstick. This means you get the full desktop and all it’s features without having to install anything, just boot from the thumbstick.
It’s a great tool for doing a quick test of your hardware, and also a great tool for recovering files from a dead Windows drive, you get to use a graphical file browser to search for files and copy/paste them to external drives.
I recommend Fedora for this, especially if your machine is a little older, Fedora retains older drivers where as most others dump them after a few years. The link I provided here gives you a Linux with a desktop that operates very similarly to Windows so it should be less confusing to look at.

And instructions on how to make a bootable thumbstick can be found on the same site:

Hard to say just what's going on. Right now I'm running a typical Windows scan to check for busted main files.
But here's what happened in today's little session just now:
I start the machine, right. It seems to be working... odd. Nothing is acting weird. Open browser, watch Youtube, okay... still not acting weird. huh.
Start a game. Nothing crazy complex. Just a 2D indie game I like. Bullet-hell, so lots of sprites. It starts out fairly okay, but as soon as it hits a sorta intense spot (not actually that intense) and the screen begins to fill with stuff, suddenly the stuttering happens. This... doesnt let up.
I can exit the game just fine, though it's clearly chugging even back at the menu. (okay, and one more try to see what'd happen and this time it didnt even get to "sorta intense". It died at like, hey there's 5 sprites on the screen)
Once back out of the game... nothing works right. Nothing. This bloody text box doesnt work right, the scroll bars dont work right, Task Manager (and Process Explorer, which doesnt register any of what's happening here on its many graphs) nearly kills itself trying to open... this will likely last until I shut the thing down again. Basically there's so much stuttering and lag that almost everything is unusable. Even the desktop itself is barely functioning.
It doesnt matter what game or whatever I try, either, from that "it's sorta working" starting point. Any game, any major program, whatever, it'll do this. Problem was first noticed when in VR, like a couple of weeks ago everything started to visually corrupt more and more, couldnt figure out why. And then a few days later and everything just goes entirely downhill all at once (and the VR stuff is utterly unusable at this point).
So, last few days, spent mostly trying anything I can think of to diagnose whatever the heck is going on. While also removing anything not immediately necessary. Nothing has come of this yet.
The browser is still sorta functional as long as I dont try to do anything else. Steam also is technically on, albeit hard to interact with (feh, may as well shut that down, then).
I'll download Fedora there though I dont think I have a usable USB drive at the moment (area is a tad cluttered here, I know I saw one somewhere...)
So yeah that's what's going on.
