I recently got a new pc a few months ago, but there's this issue I've been having for a good while. Every so often, I'll start getting MASSIVE pc slowdowns out of nowhere when using or opening google chrome, freezing my entire pc and giving me like a frame every few seconds, even when my only tab open is a new tab. This problem typically persists until I unfocus the chrome window, but restarts when I refocus it. When I restart my PC, the issues stop, but I would still like to find a definite solution. Does anybody know what's happening?

Some things I've noticed that might be relevant:

When the slowdowns happen, GPU usage is at 0%; during the times when the GPU is being used, it starts to retrurn to normal speed. However, I'm not sure what determines when the GPU starts being used or how I can configure it to always be used.

With hardware acceleration on: The above issues persist

With hardware acceleration off: It actually runs at a normal speed when the window is focused, even with (obviously) low GPU usage. However, whenever I change windows to and from Chrome, I still get the major slowdowns for a moment, which is annoying, and doesn't seem like a real solution.

There have also been cases I believe where the issue persisted into certain other programs when focused?? However, every time the slowdowns start happening, it's been while interacting with Chrome. There's a good chance this isn't even a Chrome issue and is an issue with my PC, but I figured I'd ask.
