Entire computer blackscreens when importing media

Occasionally (maybe 1 in 100) when importing media into my project, my entire computer will freeze for a few seconds, before the screen goes black for a few more seconds, then everything will begin to re-appear, kind of like when you install a new GPU driver. After which nothing will display on the program monitor until I restart the program. This also happened once upon opening a project and may have happened at other points before I started paying attention.

I have tried all of the following to no avail.

- updated GPU drivers

- updated CPU drivers

- updated OS

- updated Premiere Pro

- Checked for overheating

- took out and re-inserted GPU

- ran GPU benchmarks to check if that crashes the system (it didn't)

no idea what the actual cause of the issue is, hope someone can help me.
