Unless it's a dodgy mod with a virus in it (is that even possible?), which is why I'm curious what it is.Īlso, the age of the hardware and how long it's been since a computer has had a good defrag and disk cleanup can be a factor in performance and even basic booting. But rebooting your computer sounds like something beyond the scale of a mod. I am no computer expert though, in case that isn't obvious. When I first tried playing Deus Ex I kept getting shut-downs, and it turned out something was overheating or my RAM was fucked, I can't remember exactly what now. I have had CTDs as a result of mods, with Oblivion I would occasionally get a total system freeze, but never a shut-down.
