The attached DMP file is of the PAGE_FAULT_IN_NONPAGED_AREA (50) bug check.
This indicates that invalid system memory has been referenced.
Bug check 0x50 usually occurs after the installation of faulty hardware or in the event of failure of installed hardware (usually related to defective RAM, be it main memory, L2 RAM cache, or video RAM).
Another common cause is the installation of a faulty system service.
Antivirus software can also trigger this error, as can a corrupted NTFS volume.

First off, DV was enabled at the time of the crash:
3: kd> !verifier

All pool allocations checked on unload
Deadlock detection enabled

^^ Direct X MMS routine, specifically having to do with moving memory (moving one buffer to another).
---------------------
Was your external hooked up to the system at the time of
this crash? If so, your external is probably faulty. If it was, I'd remove it (disable verifier as well) and use the system for a few days without it. If you get no crashes, replace the external because it's faulty.
