Blue Screen 0x00000050: "PAGE_FAULT_IN_NONPAGED_AREA"

Hi,

Do you have ZoneAlarm or any 3rd party firewall installed? If so that could be the cause.
Other antivirus/security programs could be at least partially responsible.

This Hotfix "Might" apply however do not use unless you are fairly sure.

Using two Windows Filtering Platform (WFP) drivers causes a computer to crash when the
computer is running Windows Vista, Windows 7, or Windows Server 2008

-------------------------------------------------------------

You can try Safe Mode to try to fix this - repeatedly tap F8 as you boot.

Have you added any hardware lately? Have you updated any driver just before these started? (Check
Control Panel - Windows Updates to see if any drivers were updated there about the time this started)
Main likely culprits are Video driver, other major drivers, memory, and antivirus/antispyware/security
products could be at fault as well as drive issues.

Use the troubleshooter below and refer to the next message for drivers and memory when you get to
those sections and then return back to the troubleshooter as needed.


BCCode: 50     0x00000050

Cause

The BCCode 50 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.

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 theLast 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.

Look in the Event Viewer to see if anything is reported about those.

MyEventViewer - Free - a simple alternative to the standard event viewer of Windows.
TIP - Options - Advanced Filter allows you to see a time frame instead of the whole file.

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 :

BCCode: 116
BCP1: 87BC9510
BCP2: 8C013D80
BCP3: 00000000
BCP4: 00000002

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 Recovery Options if your
system has that installed by the maker.

You can try a System Restore back to a point before the problem started if there is one.

The log might give you the answer if there was a corrupted driver. (Does not tell all the possible driver issues).

Also run CheckDisk so we can rule out corruption as much as possible.

Often updating drivers will help, usually Video, Sound, Network Card  (NIC), WiFi, 3rd party keyboard and
mouse, as well as other major device drivers.

Manually look at manufacturer's sites for drivers - and Device Maker's sites.

Hope this helps.

I check a few dumps:

you get a DRIVER_CORRUPTED_EXPOOL( pool corruption ), BUGCODE_USB_DRIVER ( USBBUGCODE_BAD_SIGNATURE An Internal data structure (object) has been corrupted), CRITICAL_OBJECT_TERMINATION -  ExceptionCode: c0000005 (Access violation) andPAGE_FAULT_IN_NONPAGED_AREA.

So it looks like your RAM is damaged. Please download memtest86+ [1], burn a new bootable CD (use a CD-RW if possible) from the ISO (download and use ImgBurn [2] to do this), reboot your PC and scan your RAM 4-5hours for errors.
