I have this weird issue with my pc going on and I can't figure out what it is. Here's the deal:

>pc works fine
>connect USB storage device of any kind (tested)
>pc shits the bed by slowly getting slower and slower when reading files in explorer
>files will default to standard icons instead of previews
>opening them works fine but everything turns to icon hell
>desktop icons also disappear or change to black blocks
>can't change background and after a while I can't even open desktop settings
>can't expell USB device since it gives the: "it's busy" error
>entire explorer will just become loading hell and become unable to be worked with

I've tried:

>reboot (this works as long as I don't connect a USB storage device again, will act up within minutes if left)
>restart explorer in task manager (doesn't work)
>delete icon database so it can rebuild on startup (doesn't work)
>other USB devices like controllers work fine and don't affect it

Can't find anything about this online. Anyone has an idea what I'm looking at here? Thanks in advance.
