3.1 did the same thing. Not sure what's causing it. I've exchanged emails with tech support but there was no conclusion there, really. The only thing in the text file he (she?) asked about were that I hadn't logged in (since the problem reboots before fully loading. The program window's outline comes up then splat goes my system) and three textures. And I was told that, basically, none of that should have anything to do with the problem.

Just remembered, and I dunno if this'll help any of the more intelligent members of the forum connect any dots, but the game Dwarf Fortress (http://www.bay12games.com/dwarves/) also causes my system to reboot when I try to run it.

There has to be SOME common factor between the two. At least that's what I think. I dunno if anyone else has had Tori restart their computers lately, but ever since 3.x, it has for me. I'll keep looking. And if I actually figure out an answer, I'll post that, since I'm sure it could help SOMEONE. I can't be the only one suffering from this weird glitch X.x
