[SOLVED] A background process using a significant amount of CPU power stops immediately when I open task manager. Is there a way to identify what's doing thing?

It started a day or two ago. Three threads (I think?) jump from nearly 0% to 100% and go back as soon as I open task manager to try figure out what's causing it. My first thought was a virus or bitcoin mining trying to hide itself (though isn't that done on GPU's?), but Windows' Defender came up empty handed.

I know certain OS apps, like automatic VIRUS scans behave similarly, stopping when you click or type, but this culprit seems to only react to opening the task manager. It also doesn't start again until task manager has been closed for a while.
