One of the common cases of blue screen of death (BSOD) STOP 0x00000050 and the error message PAGE_FAULT_IN_NONPAGED_AREA in Windows 7, XP and Windows 8. Windows error 10 is also present in different variants.

The text of the error message may contain information about the file (and if it does not, it is possible to see this information in the memory dump using programs like BlueScreenView or WhoCrashed, they will be next) that caused her, among the common variants — win32k.sys, atikmdag.sys, hal.dll, ntoskrnl.exe, ntfs.sys, wdfilter.sys, applecharger.sys, tm.sys, tcpip.sys and others.

In this tutorial — the most common variations of this problem and possible ways to fix. Also below there is a list of the official Microsoft hotfix for the specific cases of STOP 0x00000050 error.

Its cause BSOD PAGE_FAULT_IN_NONPAGED_AREA (STOP 0x00000050, 0x50) generally has problems with files, drivers, faulty hardware (RAM, but not only, it can be a peripheral device), failures of Windows services, incorrect operation or incompatibility programs (often anti — viruses), and the violation of the integrity of Windows components and errors of hard drives and SSD. The essence of the problem in an incorrect memory access in the system.


The first thing to do when the blue screen of death with error STOP 0x00000050 — to remember what steps preceded the error (provided that it does not appear when you install Windows on a computer).

Note: if this error occurs on a computer or laptop once and no longer manifests itself (i.e. not constantly popping up blue screen of death), then perhaps the best solution would be to do nothing.

Here are the following typical options (some of them will be discussed in more detail)

  • Installation of new equipment, including virtual devices such as virtual drives. In this case, we can assume that the device driver for this hardware or for some reason is not working properly. It makes sense to try to update the driver (and sometimes to restore older), as well as to try the computer without the equipment.
  • Install or upgrade drivers, including automatic updating of drivers or OS installation with a driver-pack. Worth a try roll back driver in device Manager. What the driver causes BSOD PAGE_FAULT_IN_NONPAGED_AREA can often know just by the name of the file specified in the error message (just look in the Internet what this file is). Another, more convenient way will show next.
  • Installation (and removal) anti-virus. In this case, you may want to try working without this antivirus — perhaps it is for some reason not compatible with your computer configuration.
  • Viruses and malware on your computer. Here it would be good to check the computer, for example, using antivirus boot USB flash drive, or disk.
  • Changing system settings, especially if we are talking about disabling services, tweaks system and similar activities. In this case can help roll back the system from a restore point.
  • Any problems with the computer’s power (turning on not the first time, emergency stop and similar). In this case, the problem may be with RAM or disk. Can help test your memory and removal of the damaged module, check the hard disk drive, and also in some cases disabling the Windows swap file.

It’s not all options, but they may be able to help the user remember what was done before the error occurred, and may promptly correct it without any further instructions. And what concrete steps can be useful in various instances now we’ll talk.

Specific options for the appearance of errors and ways of their solution

Now for some of the quite common cases when you receive the STOP error 0x00000050 and that might work in these situations.

Blue screen PAGE_FAULT_IN_NONPAGED_AREA in Windows 10 when you start or uTorrent is a frequent option in recent times. If uTorrent is in the startup, the error may appear at Windows startup 10. Usually the reason — work with third-party firewall in the antivirus. Solutions: try to disable the firewall to use BitTorrent as torrent client.

The BSOD STOP 0x00000050 error indicating the file AppleCharger.sys — occurs on Gigabyte motherboards, if in an unsupported system was installed proprietary software On/Off Charge. Just delete this program via control panel.

When an error occurs in Windows 7 and Windows 8 with the participation file win32k.sys, hal.dll, ntfs.sys, ntoskrnl.exe first, try to perform the following: disable the pagefile and restart the computer. After that for some time to check, does the error again. If not, try to re-enable the pagefile and reboot, maybe the error will no longer appear. Read more about enabling and disabling: the Windows swap File. Also here can be useful to check your hard disk for errors.

tcpip.sys, tm.sys — the cause of the error PAGE_FAULT_IN_NONPAGED_AREA in Windows 10, 8 and Windows 7, these files can be different, but there is one more possible variant — a bridge between connections. Press the Win+R keys and type ncpa.cpl in the Run dialog box. Look at whether there are network bridges in the connection list (see the screenshot). Try deleting it (provided that you know that it is not needed in your configuration). Also in this case can help update or rollback the drivers for your network card and wifi adapter.

atikmdag.sys — one file drivers ATI Radeon, which can cause the described blue screen error. If the error occurs after you resume the computer from sleep, try to disable fast startup in Windows. If the error is not tied to this event, try a clean driver installation with advanced complete removal of the in Display Driver Uninstaller (the example described here is suitable for ATI and not just for 10-key Clean install the NVIDIA driver in Windows 10).

In those cases, when a bug appears when you install Windows on computer or laptop try to remove one of the planks of memory (on-off) and run the installation again. Maybe this time it will be successful. For when a blue screen appears when you try to update Windows to a newer version (Windows 7 or 8 to Windows 10), to help maybe clean install from a disc or USB drive, see Installing Windows 10 from a flash drive.

For some motherboards (such as seen here MSI) error may appear when switching to a newer version of Windows. Try to update BIOS from official website manufacturer. Cm. How to update the BIOS.

Sometimes (if the error was caused by specific drivers in your application programs) to fix can help clear the temporary Internet files folder C: Users Username AppData Local Temp

If it is assumed that the error PAGE_FAULT_IN_NONPAGED_AREA caused by a problem with the driver, a simple method to analyze automatically created memory dump and find out which driver caused the error will be a free program WhoCrashed (official website — After the analysis it will be possible to see the name of the driver in a comprehensible for the novice user.

Then, with the help of the device Manager you can try to rollback the driver to fix the error or remove it completely and re-install from the official source.

Also on my site describe the individual decision to separate the existence of problems — blue screen of death BSOD nvlddmkm.sys, dxgkrnl.sys and dxgmss1.sys in Windows.

Another action that can be useful in many embodiments of the described blue screen of death Windows check memory Windows. To start — using the built-in diagnostic tool memory, which can be found in control Panel — Administrative tools — check Tool Windows memory.
