Did I miss this part in all this discussion: what are common denominators each time? User and hardware, if I read it right (granted, I only skimmed the postings). Random BSODs are going to be a memory issue (hardware) -- will happen in both the VM and the host O/S.

Something else I missed further discussion on: "Upon inspection the windows folder is totally empty." -- all the files are *gone* when the happens, as in, an empty directory? Hard drive.

Forgive me if these are talked about already, but it sounds hardware related -- assuming they've all been constant throughout this. Or even power supply -- where the unit is plugged into. For example: the guy in the office across the hall from me had no issues until he got a new machine, then we noticed that every Monday when the backup generator came on and the power switched over to backup, it would BSOD and reboot. Didn't happen with the old computer -- we're chalking it up to a more sensitive power supply to the temporary drop in voltage -- most power supplies can handle this OK.
