Bsod - page_fault_in_nonpaged_area

Hi, I have been recently getting these PAGE_FAULT_IN_NONPAGED_AREA blue screens. I was wondering if you could give me any help as to what is causing them? I have included the mini-dump files below.

Thanks in advance,
Dan


EDIT - I Have just had a third blue screen this time it was MEMORY_MANAGEMENT
