Hello!
Nope, there wasn't anything in those folders and I made sure they weren't hidden for some reason as well. I've wondered that too, but I've swapped out every peripheral and tested w/o some and the problem still occurs. (Mic, earbuds, keyboard, mouse) I would have chalked that one up to electrical problems with the old house however. The only thing that was consistent between them was the house & outlets, and the hard-drive from the original PC (but only used as storage until the freeze occurred once, and then it was taken out and the problem still happened a bit later)
