Fatal Error Solutions
     
 

PAGE_FAULT_IN_NONPAGED_AREA

STOP: 0x00000050

 
  Description  
     
 

An attempt was made to access an invalid memory address due to a bug in a device driver, or hardware memory problem, or the NTFS volume is corrupt and Anti-virus software triggered the problem. In some cases the offending driver name will appear in the blue screen, although other issues described could be the source of the problem.

This is a fatal Windows error, typically called a Stop message, Bug Check, or more commonly the Blue Screen of Death (BSoD). The system is in a forced reboot state. Any unsaved work is likely lost.

 
   
  Sample Screen  
     
 

A problem has been detected and Windows has been shut down to prevent damage to your computer.

The problem seems to be caused by the following file:
filename.ext PAGE_FAULT_IN_NONPAGED_AREA

If this is the first time you've seen this Stop error screen, restart your computer. If this screen appears again, follow these steps:

Check to make sure any new hardware or software is properly installed. If this is a new installation, ask your hardware or software manufacturer for any Windows updates you might need.

If problems continue, disable or remove any newly installed hardware or software. Disable BIOS memory options such as caching or shadowing. If you need to use Safe Mode to remove or disable components, restart your computer, press F8 to select Advanced Startup Options, and then select Safe Mode.

Fix Data Corruption

    Add    Flag
solution icon

Data and/or file structures on the drive may be corrupt. Run the check disk program or other disk validation and repair utility on the drive. To do this:

  1. Open Explorer or My Computer (Press Windows+E).
  2. In the right pane, right-click on the drive you want to validate and select Properties.
  3. Select the Tools tab.
  4. Under Error-checking, click on "Check Now".


  5. In the next dialog, make sure the option "Automatically fix file system errors" is checked. If you want a more complete validation and repair check the option "Scan for and attempt recovery of bad sectors" (although this takes considerably longer to complete).


  6. Click on Start.

Several software products that offer an extensive range of disk diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.

Use Last Known Good Configuration
8
    Add    Flag
solution icon

If you are unable successfully boot into Windows because of the fatal error, Windows has an option to reload registry information from the last successful boot. To revert to the last successful boot:

  1. Reboot the computer.
  2. Near the end of the BIOS messages or graphic, but well before anything appears from Windows, press the F8 key. You may only have a few seconds to get the right spot to press F8 before it attempts to go into Windows. If the BIOS complains about a pressed key or asks you to go into BIOS setup, you've pressed F8 too soon (Don't go into BIOS setup).
  3. When successful, you should see a black screen with white text "Windows Advanced Options". Use the up or down arrow keys to highlight Last Known Good Configuration and press Enter.

Check Memory
7
    Add    Flag
solution icon

You may have a defective memory. This is even more likely if it only occurs when the system is cold or hot, but not all the time. Use a memory tester to confirm if it is defective or if you have spare memory, try replacement.

Windows 7 and Vista include a Memory Test program when booting from the Windows Installation DVD. Step-by-step instructions with screen shots are available at Using System Restore on 7/Vista/2008 as part of System Recovery.

Several software products that also provide memory and video diagnostics includes Fix-It Utilities Professional and SystemSuite Professional. Other diagnostic products include Eurosoft's PC Check and Iolo's System Mechanic.

Additional Memory Solutions:

  • Confirm all the memory is of the same type and speed. Many motherboards only work correctly when the memory is installed with matched sets and matched speeds.
  • If you added or changed your memory just before this problem occurred, try reverting to the prior memory configuration to confirm it's the source of the problem.
  • Check that the memory is fully seated in the sockets. Memory sockets often have side latches that need to be upright to indicate the memory is correctly locked in place.
  • Confirm the memory resides in the correct slots on the motherboard. You'll need to refer to the motherboard manual to confirm this. There is little consistency, even within a single vendor. Some systems require that memory is installed as matched pairs, but not always adjacent to each other!
  • It's also possible the memory problem is on the video card, as they often contain additional memory. The video card should be tested and/or try a different video card to see if the problem goes away.

It is also possible the CPU's internal memory is faulty, so run a CPU diagnostic or try a different CPU.

Remove Rootkit

    Add    Flag
solution icon
The system may have a hidden rootkit installed, a type of spyware you do not want! If your Anti-virus has rootkit detection and removal, use it to find the rootkit and if found, remove it. For more information and manual instructions to removal of the rootkit, refer to Microsoft article 894278.

If you can get the system up for more than a few minutes or can use safe mode, try removing the last installed software application or driver.

For removal of an application (Windows 8+)

  1. Press the Windows Key and X together, then  Control Panel, then Programs and Features.
  2. Select the software to uninstall and select Uninstall.

 For removal of an application (Windows 7 & Vista):

  1. Click on Start, Control Panel, then Programs and Features.
  2. Select the software to uninstall and select Uninstall.

For removal of an application (Windows XP):

  1. Click on Start, Control Panel, then Add or Remove Programs.
  2. Select the software to uninstall and select Remove.

To disable a driver:

  1. Bring up the system information dialog:

    On the keyboard, press the Windows key + Pause/Break.

       or

    Select Start, right click Computer and on the drop-down, select Properties.

  2. Click on the left side option Advanced system settings (7/Vista only).
  3. In System Properties, select the Hardware tab, then click on Device Manager button.
  4. Find the hardware/driver of interest (you may need to expand a choice at the "plus" graphic) and double click the choice.
  5. Select the Driver tab. Here you can perform a number of actions such as update the driver, roll Back the driver to an older version, disable or uninstall the driver.
  6. Click OK to exit, then close the Device Manager and other previously opened dialogs.

Get the Latest Drivers

Check if you are using the latest hardware drivers, especially the chipset and video drivers. Older drivers are a common contributor to BSoD issues.

You can use a product like Driver Genius or Radar Sync to verify you have the latest drivers and help keep all your drivers up-to-date. If you're comfortable with driver installations, you can individually find and install current drivers.

A some of the most popular driver download sites:
