I am experiencing random shut offs with my computer. It will just up and turn off abruptly and then reboot. This machine is less than 3 months old and has been working just fine up until this morning. It has done this 5 times so far, seemingly randomly. The only change of note to it in that time is an installation of the Sims 2 expansion Seasons (previous expansions and the main game have not caused any problems, nor am I convinced Seasons has anything to do with this.) Overheating doesn't seem to be an issue as my CPU is running at about 42 degrees and other temps seem okay too. Event viewer shows no errors whatsoever for today except for the most recent one. Seven minutes before my last crash there was a DCOM error: I'm not sure why it was even looking for Messenger as I have it disabled, but again this error only showed up on the most recent of crashes. I'm not sure what else to check now.
