Entire computer hangs when loading stills/previews

Windows 10 20H2
AMD Ryzen 5 3600 6-core
32gb 3200 RAM
Nvidia 3090
Project and scratch drive both NVMe
I have an ongoing issue where my machine where it pretty much hangs/stutters when rendering clip images when I first load the program. That in and itself would not be a problem but when on the cut or edit page it stutters once again when rendering the timeline previews of each of the clips, slowing down my workflow.
It seems to effect my entire computer, because when it occurs and I have a youtube video up at the same time it freezes, and my mouse freezes as well.
Wondering what could possibly be causing this? Any suggestions welcome.
