I've recently started playing clockworks again, and over the course of last couple days 5 of those occured, labelled as "IRQL_MEMORY_NOT_LESS_OR_EQUAL" (something like that). I have the windows dump files resulting from those crashes available if that's relevant.
I usually spend a lot of time either playing Lockdown or standing in Haven and this never occured to me. It only ever happens in Clockworks, namely at OCH the level before the boss and in Clockworks tunnel. Dunno if it's relevant but that's where it happened.
Thanks in advance.
