Your error is 0x00000050: PAGE_FAULT_IN_NONPAGED_AREA
This means requested data was not in memory and an invalid system memory address was referenced. This error can be caused by:
1. Defective memory (including main memory, L2 RAM cache, video RAM).
2. 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).
This is what I suggest at this time:
A. Run memtest on your RAM for a minimum of 7 Passes.
www.memtest.org
B. One processor of note is Sptd.sys which is a driver used by the CD Rom emulation program, Daemon Tools Version 4. There have been reports of problems with this driver. Google it and you'll see what I mean.
Therefore, either uninstall and then re-install or update this program.
