Just an update. I returned everything to stock settings after updating to the newest firmware and video driver provided by Dell and it still occasionally froze. I then tried uninstalling the Dell video driver in Device Manager and ran on the built in video. It ran fine for over a week. I then installed the game ready driver from Nvidia and it's been running great for about a week and a half. That might be the solution. At least for me.
Please list your XPS 8940 configuration if you are experiencing random freezes (lock ups). Dell replaced the motherboard but it's still doing it.
