Question PC keeps hitching sporadically

[Neubodyknows]

I can actually only tell it's happening via lagging mouse cursor. It becomes easier to notice in video games. Videos don't actually seem impacted at all.

This began out of nowhere and i'm not even sure when exactly it started. I've done everything imaginable; Updating drivers, unplugging this, reinstalling or uninstalling that. Everything I can possibly think of. Offline, online, no difference.
I'm now on a fresh install of windows 11 and it still happens so I guess i'm SOL but it was suggested I try here first.

I used dxdiag. The site refuses to let me paste a log into this post.

Download and run HWiNFO64 (sensors only) as you game. Wait till you experience a good amount of hitching (at least 15 mins) and see what your GPU and CPU max temps are getting up to.

What you describe is indicitive of throttling of some kind. What's your ambient room temp around? Are you in Australia (summer time)?

Well see, it happens literally all the time, gaming or no. Gaming doesn't even make it worse, nothing makes it better or worse.
I'm central north american time. Temps are all in safe ranges says HWMonitor.

Pls list the hardware?

What is CPU usage at after loading in and waiting a few minutes? Just keep Task Manager open from the time you load into OS, don't turn on or off anything else.

CPU - AMD Ryzen 7 5800X3D
MOBO - ASUSTeK X570-PLUS (wi-fi)
32gigs of RAM
GPU - AMD Radeon RX 6600

CPU usage doesn't appear suspect, usually 1% or 2 or 3, occasionally makes it up to 5%.

What is your power supply?

I am a little confused I think, in that you mention cursor hitch but say video is fine. Is this to say that even when playing games everything is loading in well but when you move the mouse the "aim" hitches as well?

Are you using a wireless mouse, distance from the PC?

I know my PSU is the oldest thing in this PC at least, I don't know exact make and model.

Like Youtube and such, it plays fine. And yes actually, my PC is decent enough that games play as good as they always have when the hitching isn't happening but the hitching affects them all the same, freezing everything for maybe a quarter of a second every few seconds.

My mouse is bluetooth, I've tried it while plugged in however and the issue remained. But I admit plugging it in probably doesn't 'turn off' the bluetooth. I'm right next to my pc, mouse is a foot away or less from it.
