Blue Screen caused by Page Fault in nonpaged error

Hello all,

In the past couple of  weeks I have been getting random BSOD appearing on my computer both when idle or when I am using it. I am a novice in figuring out what the cause could be so I'm hoping someone here could help. I have uploaded the most recent mini dump file here:

https://cid-d01a0330cedf8aef.skydrive.live.com/redir.aspx?resid=D01A0330CEDF8AEF!105

I would greatly appreciate anyone that could possibly tell me what I can do to repair this.

Thanks!

    Hi,

    Results checked with WinDBG, DumpCHK, and BlueScreenView.

    The Bug_Check was 50  0x00000050 and the CAUSE was vuhub.sys. Do you have a ASUStek

    Router? If so check for updated drivers. Also which devices can connect to the router - one

    is your computer - do you have other devices that can connect to the router that do not go

    through the computer?

    BlueScreenView shows CAUSE as afd.sys which is a Windows component (Winsock - network)

    which was driven to fault by something else. WinDBG and DumpCHK indicate that was vuhub.sys

    and in total it does strongly point to something to do with whatever devices use that driver or

    can connect through that device.

    Run DriverView if needed to see if it helps you determine to what vuhub.sys belongs (See

    next message below).

    Another way is to search for that file and Right Click on it - Properties - Details tab - any

    information there that points to its origin?

    ===========================================================

    More information to help troubleshoot if needed. References to Vista also apply to Windows 7.

    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 the Problem

    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.

    http://www.faultwire.com/solutions-fatal\_error/PAGE-FAULT-IN-NONPAGED-AREA-0x00000050-\*1095.html?order=votes

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

    http://www.nirsoft.net/utils/my\_event\_viewer.html

    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

    http://www.nirsoft.net/utils/blue\_screen\_view.html

    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.

    Hi,

    References to Vista also apply to Windows 7.

    This is my generic how to for proper driver updates :

    This utility makes it easy to see which versions are loaded :

    DriverView - Free - utility displays the list of all device drivers currently loaded on your system.

    For each driver in the list, additional useful information is displayed: load address of the driver,

    description, version, product name, company that created the driver, and more.

    http://www.nirsoft.net/utils/driverview.html

    For Drivers check System Maker as fallbacks and Device Maker's which are the most current.

    Control Panel - Device Manager - Display Adapter - write down the make and complete model

    of your video adapter - double click - Driver's tab - write down the version info. Now click UPdate

    Driver (this may not do anything as MS is far behind certifying drivers) - then Right Click -

    Uninstall - REBOOT this will refresh the driver stack.

    Repeat that for Network - Network Card (NIC), Wifi, Sound, Mouse and Keyboard if 3rd party

    with their own software and drivers and any other major device drivers you have.

    Now go to System Maker's site (Dell, HP, Toshiba as examples) (as rollback) and then Device

    Maker's site (Realtek, Intel, Nvidia, ATI as examples) and get their latest versions. (Look for

    BIOS, Chipset and software updates at System Maker's site while there.)

    Download - SAVE - go to where you put them - Right Click - RUN AD ADMIN - REBOOT after

    each installation.

    Always check in Device Manager - Drivers tab to be sure the version you are installing actually

    shows up. This is because some drivers rollback before the latest is installed (sound drivers

    particularly do this) so install a driver - reboot - check to be sure it is installed and repeat as

    needed.

    Repeat at Device Makers - BTW at Device Makers DO NOT RUN THEIR SCANNER - check

    manually by model.

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

    Installing and updating drivers in Windows 7 (updating drivers manually using the methods above

    http://www.sevenforums.com/tutorials/43216-installing-updating-drivers-7-a.html

    If you update drivers manually then it is a good idea to disable Driver Installations in Windows

    Updates, this leaves Windows Updates ON however it will not install drivers which will usually

    be older and cause issues. If Updates suggests a new driver then HIDE it (Right Click on it)

    and then go look for new ones manually if you wish.

    ==========================================

    Memory tests do not catch all errors such as mismatched memory (possible even for sticks

    that appear to be identical) and when faster memory is placed in system behind slower memory.

    So it is best to also swap sticks in and out to check for those even if all memory tests fail to show

    a problem.
