Similar to this post , I've been having BSODs on and off over the last few months. I can't say anything changed when they started. It's always related to memory - MEMORY_MANAGEMENT and PAGE_FAULT_IN_NONPAGED_AREA. Taking the memory out then re-seating it solves the problem for a few weeks, then it starts again. I don't know why, but it might be related to dust - it's very dusty where I am. I've attached what I think are they require files/screen shots.
