Your minidump is error 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA
Requested data was not in memory. An invalid system memory address was referenced. Defective memory (including main memory, L2 RAM cache, video RAM) or incompatible software (including remote control and antivirus software) might cause this Stop message, as may other hardware problems (e.g., incorrect SCSI termination or a flawed PCI card).
Unfortunantly it only cited the Windows OS driver dxgkrnl.sys as the cuprit and usually these OS drivers are too general to be of much help.
Do you have any more recent minidumps, say five and not including the one you gave, that you can attach in your next post?
