only ask, as for me most crashes aren't game related and tend to be something else thrown into the mix i've found, while some are bugs, most tend to be some app or program doing something at the same time in the background at the same time the game does something, and they class, find out what the item is, then you have a part solution.
things to check,
windows error reports / depending on system can be called, event viewer in system management
anti virus logs
crash reporter logs
stuff to try, run resources manager and performance manager at the same time the game is running and make sure both are set to log
use a good cache cleaning app before hand and like CCleaner run a reg repair tool also, then anything found or fixed or removed after the event will be new logged stuff and not old stuff.
is the pc a clean installed one? or an updated from a older O/S one, it all helps,. the more info the better, not saying it will fix it or help at all, but sometimes something pops up that surprises yourself and you say, yes i know now what it is and how to get round it.
maybe something as simple as running at a high privilege level in windows, or disabling something while your gaming.
hope some or my spam helps
