That sounds pretty bad! I write hydrus in python, so I normally cannot cause a blue screen even if I wanted to, but the only exception I have seen to that was when some graphics drivers were causing it, and Hydrus's calls to 'OpenCL', which is GPU acceleration for image loading, were triggering that bug. it was Nvidia drivers, and the fix was to update to the new version.
Have you had any GPU issues recently? If you go into your driver options and disable OpenCL for client.exe, does that help?
It may not have been repo processing, but some file maintenance like video reparse or thumbnail regen happening in the background.
I recommend pausing repo processing under services->pause
and file maintenance under database->maintain->file maintenance
if you want to test more.
