Had the same issue after a break between 1.5 and 1.6 and could have helped this guy easily solve the issue but for some reason the thread is locked. Do we just lock threads now without even a Moderator response or a reason at all? Anyway OP of this thread: http://www.gamesas.com/topic/1397699-ugh-skyrim-auto-shut-down-during-load-help/
PM me on the boards here or reply on this thread and I will help you fix the issue.
Mods dont discuss reasons for locking threads. But that was obviously locked because it was a duplicate thread which is against the forum rules. This will probably get locked also.
We should always post a reason for a close, that one was overlooked for some reason. There is a topic discussing and answering this as linked by Yasgur. Thanks.
