So, I was animating a scene, not too complex, and playback was fine, then I found out my windows was outdated so I clicked update and restart, it then took 5 attempts to get back into the computer as the CPU would malfunction, and when I did, the same scene(no changes) couldn't even get past 18 fps. Nothing I've tried works, I updated my graphics drivers and everything.

Does anyone have a clue as to what happened and more importantly, how to fix it?
P.S. All other cases of this happening were because of an underpowered system. This time, it was working fine and now it isn't.
