Question
BSOD Windows XP Page_Fault_In_Nonpaged_Area Stop: 0x00000050
I was getting the BSOD caused by a driver for Alcohol 120 for a virtual CD drive, so I uninstalled that and everything seemed to work fine.
Now I'm getting the BSOD for something different.
Page_Fault_In_Nonpaged_Are
The BSOD only happens when I try to do a virus scan, or a registry scan or search the registry. I doesn't happen any other time, ie: playing a game, burning a DVD or watching a movie.
I've tried online virus scans and keep getting the same result, BSOD.
I have swapped out my mem sticks with 2 known good ones, but still keep getting the stop during virus scan caused by : ntoskrnl.exe
Found this from Google, ntoskrnl.exe is a critical process in the boot-up cycle of your computer
Is there a way to repair this file ?
This is the latest mini dump:

Could be for a number of reasons, as listed here>
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).

I would try doing a system restore to a date before Alcohol was installed. There are probably hidden non-plug and play system drivers (like sptd.sys) that are hanging around. I've had similar problems with Daemon tools, another virtual CD drive software. You could try to troubleshoot it, but system restore is usually the easiest way to go. Here's some instructions:
