okay, Definitely not windowblinds, I've been adding applications from Object Desktop one at a time over the last few weeks. I've narrowed it down to shadowfx. If shadowfx is installed and I start using VMware WS 11.1 heavily. My PC will reboot. I know it doesn't make sense, but I am staying stable now with shadowfx uninstalled.
edit- shoot, not shadowfx either. Still need to narrow down more. definitely went a week with all OD items uninstalled, and no incident.
Edit again, have isolated outside of stardock, (finslly)
