If you suddenly encounter the PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error then it means that your computer is under a heavy load. And if you look closely, you’ll see that it has a bug check value of 0x00000050. This kind of Blue Screen error also indicates that invalid system memory has been referenced. It could be that the memory address is wrong, or that it is pointing at freed memory. The PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error occurs when the requested data is not found in the memory. As a result, the system generates a fault which normally indicates that the system is looking for data in the paging file. However, in this case, the missing data is identified as being located within an area of memory that cannot be paged out to the disk. This Stop error might be caused by a buggy system service, antivirus program, a corrupted NTFS volume, or faulty hardware. So if you’ve recently added hardware, you can try removing it and then check. If the problem still persists, refer to the suggestions given below to fix the problem.

Option 1 – Run Memory Check to test your memory

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Select the option you prefer and afterward, check if the Blue Screen error is now fixed.

Option 2 – Run a System File Checker scan

You can also try to run a System File Checker or SFC scan in order to scan your computer for corrupted files that might be the cause behind the PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error. Once it finds any corrupted system files, it will automatically fix them. To run System File Checker, here’s what you have to do:

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer after the scan is completed.

Option 3 – Disable Automatic Paging File Size Management

• Right-click on This PC located on your desktop.
• Next, click on Properties and then click on the Advanced System Settings.
• Go to the Advanced tab and then click on the Settings button under the Performance section.
• Afterward, a new mini window will appear and from there, go to the Advanced tab.
• Then click the Change button under the Virtual Memory section. Once you do, another mini window will appear.
• Now uncheck the “Automatically manage paging file size for all drives” option.
• After that, you have to increase the Page File size by doubling the amount of memory allocated by default in the text field. For instance, the paging size given is a minimum of 16MB and so you have to change it to 32MB. And since the recommended value is 1907MB, you can make its maximum size around 4000MB. By doing so, it will allocate more space for paging into individual drivers.
• Now click OK, close all the open windows and then restart your PC.

Option 4 – Update the Device Drivers

Updating the Device drivers can also help you fix the PAGE_FAULT_IN_NONPAGED_AREA Blue Screen error. To do so, follow the steps below.

If you suddenly find the middle mouse button not working as you use it on your Windows 10 computer, then you’ve come to the right place as this post will provide some suggestions that can help you fix the issue. This kind of problem can affect your experience in using your computer as the middle mouse button helps you in scrolling through long web pages and screens with a lot of data. So if that stops, you will end up using your keyboard instead which is kind of a hassle compared to using the middle mouse button. It is possible that this problem could have something to do with either the hardware or software. To isolate the possibility of a hardware failure, you can try to connect the mouse to a different computer and see if it works just fine there or if it still has the same problem. If the mouse works properly on a different computer, then the issue is software-related. It is possible that a software update, especially gaming software, could have been misconfigured in a way that the middle button does not respond like it’s supposed to. To resolve the problem, you might want to try reinstalling or updating the mouse drivers or run the Hardware and Devices troubleshooter. You can also install OEM-specific mouse drivers or modify some entries in the Windows Registry.

Option 1 – Reinstall or update the Mouse driver

The problem may be caused by a corrupted or an outdated mouse driver. To fix it, you have to update or reinstall the mouse driver. How? Follow these steps:

• Open the Devices Manager from the Win X Menu.
• Then locate the Mouse and other pointing devices and right-click on the mouse driver to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, disconnect the mouse and plug it back in to reinstall the mouse driver.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 2 – Try running the Hardware Troubleshooter

The next thing you can do to fix the problem is by running the Hardware Troubleshooter. Although it won’t make much of a difference, there’s still a possibility that it could automatically fix the problem with these function keys. To use it, refer to these steps:

• The first thing you need to do is click on Start and then on the gear-like icon to pull up the window for Settings.
• After opening Settings, look for the Update and Security option and select it.
• From there, go to the Troubleshoot option located on the left-hand side of the list.
• Next, select Hardware and Devices from the list and open the Troubleshooter and run it. Once it is doing its job, wait for it to complete the process and then restart the system.
• After the system restarts, check if the problem’s now fixed. If not, refer to the next option given below.

Option 3 – Try to install OEM specific mouse drivers

Aside from updating or reinstalling the mouse drivers, you might also want to try installing OEM-specific mouse drivers. When you install Windows, it will use a generic driver for all its components. The disadvantage of generic drivers for the mouse is that it limits its functionality. In fact, some also configure the middle mouse button to respond to specific action which does not work without the correct drivers. In such cases, you need to visit the website of your computer’s manufacturers to download and install the latest drivers and then open the software and configure it the way it was before. Keep in mind that some OEMs also offer gestures, so you also have to check on that.

Option 4 – Try to modify some entries in the Registry

If a Windows Update is the one that caused the problem, you could correct it by making some modifications in the Registry but before you proceed, make sure that you create a System Restore point first.

• Tap the Win + R keys to open the Run utility.
• Then type “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_CURRENT_USERControl PanelDesktop
• After that, double click on the “WheelScrollLines” entry on the right pane to open its Properties.
• Now change its value data to “3” and exit the Registry Editor and then see if the issue with the middle mouse button is fixed or not.
