The PAGE_FAULT_IN_NONPAGED_AREA bug check has a value of 0x00000050. This indicates that invalid system memory has been referenced.
Important Info If You Have Received a STOP Code
If you received a blue screen error, or stop code, the computer has shut down abruptly to protect itself from data loss. A hardware device, its driver, or related software might have caused this error. If your copy of Windows came with your computer, call the manufacturer of your computer. If you purchased
Windows separately from your computer, Microsoft provides support. To find contact info for Microsoft or your computer manufacturer, Contact Support.
If you have experience with computers and want to try to recover from this error, follow the steps provided in the Microsoft article Resolving STOP (Blue Screen) Errors in Windows.
These actions might prevent an error like this from happening again:
- Download and install updates and device drivers for your computer from Windows Update.
- Scan your computer for computer viruses.
- Check your hard disk for errors.
Memory address referenced
0: Read operation
1: Write operation
Address that referenced memory (if known)
If the driver responsible for the error can be identified, its name is printed on the blue screen and stored in memory at the location (PUNICODE_STRING) KiBugCheckDriver.
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.
Resolution Resolving a faulty hardware problem: If hardware has been added to the system recently, remove it to see if the error recurs. If existing hardware has failed, remove or replace the faulty component. You should run hardware diagnostics supplied by the system manufacturer. For details on these procedures, see the owner's manual for your computer.
Resolving a faulty system service problem: Disable the service and confirm that this resolves the error. If so, contact the manufacturer of the system service about a possible update. If the error occurs during system startup, restart your computer, and press F8 at the character-mode menu that displays the operating system choices. At the resulting Windows Advanced Options menu, choose the Last Known Good Configuration option. This option is most effective when only one driver or service is added at a time.
Resolving an antivirus software problem: Disable the program and confirm that this resolves the error. If it does, contact the manufacturer of the program about a possible update.
Resolving a corrupted NTFS volume problem: Run Chkdsk /f /r to detect and repair disk errors. You must restart the system before the disk scan begins on a system partition. If the hard disk is SCSI, check for problems between the SCSI controller and the disk.
Finally, check the System Log in Event Viewer for additional error messages that might help pinpoint the device or driver that is causing the error. Disabling memory caching of the BIOS might also resolve it.

Here are some methods to possibly fix the blue screen issue. If you could give the Blue Screen
info that would help. Such as the BCC and the other 4 entries on the lower left. And any other
error information such as STOP codes and info such as IRQL_NOT_LESS_OR_EQUAL or PAGE_FAULT_IN_NONPAGED_AREA and similar messages.
As examples :
or in this format :
Stop: 0x00000000 (oxoooooooo oxoooooooo oxooooooooo oxoooooooo)
tcpip.sys - Address 0x00000000 base at 0x000000000 DateStamp 0x000000000

Many BlueScreens are caused by old or corrupted drivers, especially video drivers however
there are other causes.
You can do these in Safe Mode if needed or from Command Prompt from Vista DVD or

el equipo está infectado con una variante del virus HaxDoor.
El virus HaxDoor crea un proceso oculto. También oculta archivos y claves del Registro. El nombre del archivo ejecutable del virus HaxDoor puede variar, pero suele ser Mszx23.exe. Muchas variantes de este virus introducen en el equipo un controlador denominado Vdmt16.sys o Vdnt32.sys. Este controlador se utiliza para ocultar el proceso del virus. Las variantes del virus HaxDoor pueden restaurar estos archivos si los elimina.
post Nr 70
It turned out that my problem arose not directly from changing my hard drives...but from using a cloning program (Acronis True Image) to do it. While I don't know the technical issues involved, suffice it to say that this was the problem. And for those who may have the same problem, here is the solution as noted in the referenced post:
1. Go to windows Device Manager
2. Click "view" and select "show hidden devices"
3. Scroll down to "storage volumes"
4. Click on the plus to expand.
5. Click on each one listed and right click and uninstall. (you will get a message on some saying to reboot before it takes effect. Select no until you do them all.)
7. Wait till windows automatically reinstalls devices. Will prompt to reboot again.
Now it should work.
