Page_fault_in_nonpaged_area – If you’re a Windows user, you must have come across this error at some point. It shows up against the dreaded Blue Screen of Death (BSOD) with the error code 0x00000050 and ends with your computer crashing.

While it mostly occurs when your system refers to invalid memory, there can be other reasons, too. Read on as we discuss the various solutions to this problem.

Why Is The page_fault_in_nonpaged_area Happening?

Page fault errorThe computer stores data on different components like the RAM and the hard drive. When these components are full, the data is swapped between the page file and RAM.

So when the system requires data stored on the Page file and isn’t able to find it, you end up seeing the “page fault in nonpaged area” error on a blue screen.

The Reasons Behind the Error

In some cases, the error syntax might include the cause of the issue, like ‘Page_fault_in_nonpaged_area (ati.sys). Here, the .sys file indicates that the program was trying to get access to parts of memory that it shouldn’t.

In other cases, there might be no indication of the underlying issue and it can either be software or hardware-related. It doesn’t just take place out of the blue; it usually takes place after an app or Windows update, a change in the graphics card or RAM, or after you installed something new.

Some other causes of this error include:

  • System referencing to discharged memory or incorrect memory addresses
  • Antivirus software and online security solutions that prevent the OS from finding the required data in the nonpaged area
  • Incorrect Windows service
  • Corrupted NFTS volume
  • Wrong driver codes detected in the system
  • Faulty or corrupt hardware, such as the RAM, causing the requested data to be lost

How To Fix page_fault_in_nonpaged_area

Since there are a number of reasons for this nonpaged area error, you will have to try out a number of solutions to solve the problem. Below are some common fixes that usually get rid of the error.


– Check Your RAM

If you have just recently added new hardware to your Windows PC, it’s a good idea to inspect if everything is properly fixed in its respective slot. Sometimes you can end up with faulty RAM sticks, or your old ones can also malfunction, which is why you should also check the RAM.

To do so, first, switch off your system and disconnect all the wires.

Then, below are listed some points you can do:

  • If you have two memory sticks added to your computer, switch their slots to see if that solves the problem. Or, just try using one slot.
  • If you only have one stick, take it out and clean it to get rid of any accumulated dust.
  • If you have a spare RAM chip at home, try replacing it with the one on your computer and restart it. If you don’t see the error, then it means your RAM is faulty.

– Rollback, Update or Uninstall Drivers

Faulty device drivers can cause a plethora of problems, which is why it’s best to update them. The BSOD error usually occurs because of faulty chipset, graphics, audio, or display drivers, and you should update those if checking the RAM doesn’t solve the problem.

The simplest way to keep your drivers updated is by using the Device Manager. You can find the graphics drivers under the Display adapter and chipset drivers under System devices.

Here’s how you can manually update your drivers:

  1. Press the R and Windows keys together to launch the Run dialog box. In the text box, type devmgmt.msc and press Enter. This will open the Device Manager.
  2. You will see a catalog of drivers on the screen. Choose the one you want to update and click on it to expand the menu.
  3. Right-click on the particular driver you want to update. Then click on Update driver.
  4. On the next screen, click on “Search automatically for updated driver software.”
  5. The latest drivers will automatically be downloaded and installed.

However, in some cases, the latest updates can be unstable and can result in error. If that’s the case, you should roll back your drivers to their previous, stable versions. If you still see page_fault_in_nonpaged_area on the screen, try uninstalling the drivers altogether.

– Disable Automatic Paging Management

Page fault update windowsThe paging file directly deals with virtual memory and is often the culprit behind the page_fault_in_nonpaged_area error.

Typically, your Windows manages the paging file. However, it’s best to disable it if it’s making your system crash.

Here’s how:

  1. Open up File Explorer.
  2. Right-click on This PC and choose Properties.
  3. On the panel on the left side of the screen, click on Advanced system settings. This will open up the System Properties. Just make sure you’re signed in as the admin.

  5. Go to the Advanced tab, and in the Virtual Memory section, click on Change.
  6. Uncheck the box that says “Automatically manage paging file size for all drives” and click OK.
  7. Apply the settings and reboot the PC.

If your computer works fine once you reboot, then you don’t need to do anything else. However, if you still see the page_fault_in_nonpaged_area problem on a blue screen, revert all the changes and check the box that says “Automatically manage paging file size for all drives.” Then apply the changes.

– Run chkdsk

Chkdsk or check disk is a disk checking utility that finds and fixes file system and disk errors. Here’s how you can run it:

  1. Run the Command Prompt as the administrator.
  2. In the cmd, type chkdsk /f /r and hit Enter.
