Small micro-second spike/stutter every second, regardless of activity

Oct 26, 2021
As the title suggests my computer, is stuttering every half second or so regardless of what I'm doing. This is not an FPS problem in video games, it stutters when scrolling or just moving my mouse around.

I have Windows 10, RTX 2060S FE, R7 3700x at 4.25ghz

Here is a video showing the problem, I've updated drivers and turned off shadow play to just see, and that wasn't the issue.
