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:
Windows Resource Protection did not find any integrity violations.
Windows Resource Protection found corrupt files and successfully repaired them.
Windows Resource Protection found corrupt files but was unable to fix some of them.
Restart your computer after the scan is completed.
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.
Tap the Win + R keys to launch Run.
Type in devmgmt.msc into the box and tap Enter or click OK to open the Device Manager.
After that, a list of device drivers will be displayed. If you see a red or yellow sign that shows up against the driver, right-click on the driver and select “Update Driver Software”.
Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
Restart your PC and then check if the Blue Screen error is now fixed or not.
Option 5 – Perform a System Restore
Performing System Restore might help you in fixing the PAGE_FAULT_IN_NONPAGED_AREA error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.
Tap the Win + R keys to open the Run dialog box.
After that, type in “sysdm.cpl” in the field and tap Enter.
Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
Option 6 – Try disabling your antivirus programs
There are instances when antivirus programs trigger Stop errors like PAGE_FAULT_IN_NONPAGED_AREA. Thus, you can try disabling your antivirus programs like Windows Defender or other third-party programs if you’re using one.
Option 7 – Use the Blue Screen Troubleshooter
The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like PAGE_FAULT_IN_NONPAGED_AREA error. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:
Tap the Win + I keys to open the Settings panel.

Method Five: Use An Automated Tool
If you wish to always have at your disposal a utility tool to fix these Windows 10 and other related issues when they do arise, download and installa powerful automated tool.
Windows has a lot of built-in tools that help you fix tons of system-related issues. One of them is the System File Check which is the tool you can use to conveniently replace potentially corrupted or missing system files with good ones. But what happens when it does not work? Well, you’ve come to the right place as in this post, you will be guided on how you can replace a corrupted single Windows system file manually with a known good copy of the file if the System File Checker scan is not working.
When you encounter this issue with the System File Checker, it will be unable to replace the corrupted system files and returns an error message instead. And so to fix and replace corrupted system files in your Windows 10 computer without the help of System File Checker, you can refer to the instructions provided below.
Step 1: First, you need to open the log files listed below and identify which particular file has been corrupted:
%userprofile%Desktopsfcdetails.txt
Log %WinDir%LogsCBSCBS.log
Step 2: You will see all the details on the given log files. Once you find out the name and the path of the file, you have to take ownership of this corrupted system file.
Step 3: To take ownership of the corrupted file, you need to pull up Command Prompt by tapping Win + R keys on your keyboard and then type “cmd” and tap Enter.
Step 4: After opening Command Prompt, type and enter the command below to execute it:
takeown /f FileNameAndPath
Note: In the given command, “FileNameAndPath” represents the name and the path of the corrupted file. For instance, the corrupted file is named “wuapi.dll”, then you need to type “takeown /f C:/Windows/System32/wuapi.dll”
Step 5: Next, you need to grant administrators full access & control to the corrupted file and you can do that via Command Prompt again.
Step 6: In the elevated Command Prompt, type and enter the following command to execute it:
icacls FileNameAndPath /GRANT ADMINISTRATORS:F
Note: We’re going to use the wuapi.dll again as an example. So the command should be like this: icacls “C:/Windows/System32/wuapi.dll /grant administrators: F”.
Step 7: Now all that’s left to do is replace the corrupted system file with a good copy from a trusted source. Once you have a copy, open an elevated Command Prompt again and execute the following command:
copy NewFileLocation FileNameAndPath
Note: In the command given above, the “NewFileLocation” is the location where you have saved the copy of the file. For instance, if you’ve saved it on your desktop, this is how it should look: “copy C:/Users/<username>/Desktop/wuapi.dll C:/windows/system32/wuapi.dll”
In case you don’t know, there is a feature in Windows 10 computers that allows them to function a lot better. This feature is called Full-Screen optimization and it is enabled by default for several applications such as games and video players. If enabled, the Full-Screen optimization feature enhances the video playback and gaming by simply putting the CPU and GPU process as a priority. However, there are times when it can also result to a drop in the frame rate or FPS while in full-screen mode. And of course, the obvious solution to this dilemma is by disabling the Full-Screen optimization feature which is why Microsoft took action and removed this feature themselves in the recent Windows 10 Update releases. However, there is another way for you to enable it back or disable it yourself if you haven’t installed the recent updates yet and there are plenty of ways you can do both. All you have to do is follow the options given below carefully.
Option 1 – Try using Windows 10 Settings
If you haven’t installed the recent updates yet and all you have are the earlier releases, then this method would suit you.
Open the Windows 10 Settings app.
Next, navigate to System > Display > Graphics Settings or Advanced graphics settings.
From there, uncheck the “Enable Fullscreen optimization” option if you want to disable the feature, else just keep it checked.
Option 2 – Try using the Registry Editor
Tap the Win + R keys to open the Run dialog box and then type “Regedit” in the field and hit Enter to open the Registry Editor.
Afterward, if a User Account Control or UAC prompt appears, click on Yes.
Once the Registry Editor is pulled up, navigate to this registry key: HKEY_CURRENT_USERSystemGameConfigStore
Next, right-click on Explorer and select New > DWORD (32-bit) Value and then name it to “GameDVR_DSEBehavior and tap Enter to save it.
Now double click on the newly created GameDVR_DSEBehavior DWORD and set its value to “2” if you want to disable it, or “0” if you want to enable it.
Once you entered the value, close the Registry Editor and restart your computer to successfully apply the changes made.
Option 3 – Try running the application in Compatibility Mode
If the first two options didn’t work, the next thing you can do is to run the application in a Compatibility Mode. Follow the steps below to do so:
Go to the location of the application or game on which you need to disable or enable the Full-Screen optimization feature.
After that, right-click on it and select Properties.
Next, switch to the Compatibility tab where you can see the “Disable fullscreen optimization” option to disable the feature and vice versa.
Now click on the Apply and OK buttons to apply the changes made in the application’s settings.

Hello and welcome to our Increasing Virtual Memory tutorial. Before trying to raise the quantity of virtual memory in your pc system, it's important to get a comprehension of its goal and use.
This leads to the constant use of high-performing tasks in addition to keeping multitasking capability.
The downside to this process is the fact that relatively, the HDD accesses information slower than a RAM module.
Taking into consideration its use in a computer program and how virtual memory works, there isn't any amount of virtual memory allocation.
The quantity of virtual memory to be defined for a unique computer program would be determined by the kinds of programs that are started and the quantity of multitasking done. The Microsoft Windows operating system yet does supply a recommended baseline memory based on the number of RAM installed and storage space of the HDD.
Virtual memory allocation really indicates the upsurge in how big the paging file is. This file provides the pc program with all the essential instructions on the best way to act once all the installed RAM has been allotted to the running applications. In both Microsoft Windows XP (all variants) and Windows Vista environments, the method to control the paging file size is basically the same. To increase the quantity of virtual memory:
Click on the Start menu and choose the "Control Panel" alternative. When the Control Panel window is started, choose the "Operation and Maintenance" class.
Click on the "System" choice to create the Device Properties Window.
Click the "Advanced" tab and choose the "Settings" button under Operation. In the Operation alternative window, select the "Change" button under the Virtual Memory class.
Choose the hard disk where the Windows operating system is now installed. That can be the same place where in fact the paging file will be saved.
Test on the checkbox for the "Custom Size" to enable you to determine the number of virtual memory you need to use for your device.
Click the "OK" button thrice to shut all of the windows. Click the Start button and restart your machine to enable the upsurge in the number of virtual memory to be finished.
In establishing the number of virtual memory, you'll have to place a maximum value along with an initial. It is suggested that both values be equivalent in order to achieve the finest performance on your pc system.
Started as an internal network and has slowly expanded since 1960 internet has taken over the world. In the beginning, it was a means of information change but in the modern age you can run applications and virtual machines over the internet, you can stream video and audio, and you can communicate in real-time with someone on the other side of Earth.
With the internet growing so fast in such a small amount of time it is only logical and wise to take a step back and take a good look at what it offers now, what are great things about it and what are some of the worst.
Good sides of the internet
Information
There are a lot of advantages of the internet, first and foremost is information. Internet was made as an information exchange service and even today you can find a lot of various information about various topics that interest you. A site like Wikipedia is a completely free online encyclopedia and a lot of news companies have their own internet sites where you can find free information and news.
On the other hand, there are also websites like udemy, edx, Coursera, and many others that will offer you the education, some for free, some for money but you can get a glimpse and part of university quality education for just a fraction of price.
Online shopping
Sites like Amazon have used the internet and launched themselves as today's multi-billion companies. In today's world, there is not a single thing you can not buy online. Many sites today are going from the large online marketplace where you can find everything to small niche specialized ones. Also every major brand in the world today has its own online store.
Other shops will offer you music, movies, games, etc. Services like steam, xbox pass, sony pass etc, will let you buy games online, other music, movies, and many more.
Streaming services
Days, when you had to buy movies in order to watch them at home, are gone, thanks to the internet we have plenty of streaming services for movies and tv shows as well as ones for music. If you do not want to spend money on actually purchasing things then a good idea is to have a streaming plan set up when you want it.
Email and messaging
Communication is a great thing and since the dawn of mankind people have been talking and sharing with each other, the internet has made it possible to send mail electronically and instantly and modern chat communication is everywhere. We can not just talk with our friends and family that can be on the other side of the world, we can also talk in real-time with the sales representative, with technical service, or attend online classes with a group of people.
Cloud storage services
Saving your pictures in this digital media age on the hard drive can be risky but thanks to modern technologies you can save most of your precious files on cloud servers for safekeeping. From pictures to documents and even other files that you need and want to save. There are some of them that will offer you a free amount and some basic free plans as well.
Bad sides of the internet
Malware, viruses, and phishing
We could not talk about the bad side of the internet if we do not mention its greatest threat. Bad sites, infected software, phishing emails, and many more malicious threats. Problem is that these kinds of tricks and attacks have become more and more sophisticated and harder to detect and avoid.
Pornography
Pornography is bad, having it freely available to children is even worse. Sadly the only way to regulate this is on a computer-by-computer basis by turning on parent control on each one. There are many studies that go into detail about why this is bad, sadly currently there are no effective ways to isolate this content.
No privacy
When we say there is no privacy we do not mean by using social media and not setting your privacy settings altho that also fits in this point, what we are talking about is data mining of your habits and things you do. It is well known that today lot of websites are using some form of AI recommender system in order to tailor your internet experience to suit your needs better. Most of these AI systems are trained by mining your data and analyzing your habits.
If you have 2 google accounts there is a high probability chance that for the same query you will get different results, depending on your so far browsing habits. The same goes for other services as well.
Dark webshops
There are some great things in dark and deep WEB-like sites with true news and information. Even some legit libraries where you can find and download rare books. Sadly as goes with the internet dark and deep WEB also has its well, dark sides, from disturbing content to shops that sell stolen items to straight stealing your money by parading as legit shops but only to steal your money.
Dating sites
We all try to find someone that is perfectly matched with us but using the online dating site has many proven bad effects on psychology. It also devaluates interaction between people and can lower self-esteem.
Bad habits
Since the internet has become wildly available and popular on various devices like tablets and mobile phones more and more people are spending an unhealthy amount of time on it. Harvesting the benefits of the internet is great but find some time for other people as well.
The new thing from Mozilla is not a browser, it is a VPN!
Besides Firefox, Mozilla offers now Firefox Relay, an app helping you to mask your email and phone number, and a new Mozilla VPN.
Mozilla has recently announced a new subscription model that will let you use all products together for $6.99 per month. Although this is a little more expensive than the competition that goes around for $5 per month note that with this subscription you are having access to all services, not just VPN.
VPN will not only hide your IP address but will also make sure websites cannot access your real location and it encrypts all of your network activity. Relay will give you protection against spam, serving as a shield for your email and limiting spammers from access to your real email address and phone number. With Mozilla subscription will let you use both services.
Google Chrome is the most used browser in the world with the most user downloads. Most users are using browsers how it is, open it up and just surf but Chrome offers more than just plain surfing. Here we are presenting you with some interesting features that most users do not use but should.
Use Omnibox to search inside websites
Chrome's Omnibox, also known as the address bar got its name because it can do much more than just search the internet. You already probably know that just by typing any word you will search the internet with Google or another search engine of choice.
You can also set specific keywords inside Chrome settings to tie them with specific websites, for example, you can tie the letter E with errortools, and then just by typing E windows error you will search term windows error on website errortools. There are some already predefined things and you can add anything you want so this is a great feature in order to speed up your work skipping part of actually opening the site.
Search the internet for selected text
On any webpage, you can simply select any text and right-click on it to get a new menu entry that will say search Google for "your selected text" and by clicking on it you will automatically search the net for the selected term.
Grouping tabs
When we surf the internet some of us tend to have plenty of open tabs and over time they can clutter and shrink in width making the surfing experience an unpleasant one.
Chrome has tab groups and you really need to start using them since you can organize much better all the tabs, even color-code them.
Search all open tabs
On top right part on title bar right next to minimize button there is small arrow pointing down, once you clik on it all opened tabs will be displayed by name as a listand by clicking on it you will automatically switch to it.
Change download location
Google Chrome has its default download destination but you can change that destination and even turn on option to be asked where you would like your download to be saved each time.
Live Captions
YouTube has cations for its videos but Chrome itself has live caption option in order to provide you with automatic AI captions for any type of video or audio on any website. If you are struggling with following what is being said try this awesome option.
Extensions
Using extensions in Chrome is awesome, specialy if extensions are usefull but if you go incognito they are not active. There is an option in Chrome to turn on the extensions even in incognito mode and even better, you can even choose which ones you want to be active, you do not need to turn all of them.
If you’re having some problem browsing multiple websites on the Firefox browser on your Windows 10 computer, then this post might be of help. One of the most common problems you could encounter in Firefox is mostly related to HTTPS and one of them is the MOZILLA PKIX ERROR MITM DETECTED or ERROR SELF SIGNED CERT or SEC ERROR UNKNOWN ISSUER error which means that Firefox was unable to trust certificates issued on secured websites.
If you encounter the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox, this indicates that something in your network or system is interrupting your connection and injecting certificates and when that happens, Firefox won’t trust it. In such cases, one of the culprits is malware. Malware will try to replace a legitimate certificate with its certificate. Another cause is security software where it keeps a tab on a secure connection and creates a false positive, for instance:
“In Microsoft Windows accounts protected by Family Safety settings, secure connections on popular websites like Google, Facebook and YouTube might be intercepted and their certificates replaced by a certificate issued by Microsoft in order to filter and record search activity.”
And if you are connected to a corporate network, there might be a monitoring/filtering product that could be replacing certificates. Moreover, there are also users who reported getting this issue when they use the Nightly version of Firefox. And if that’s the case, you have to try accessing secure websites using only the stable build especially when it comes to payments. However, if you are not doing that, then here are some options you need to check out.
Option 1 – Try turning off HTTPS Scanning on your security and antivirus programs
Each security-based software has a security option that allows you to turn off the HTTPS scanning functionality. They may be available under different names such as HTTPS Scanning, Scan SSL, Show safe result, Do not scan encrypted connections, etc. Find what is applicable for your security or antivirus software and then try turning it off temporarily and see if it helps in fixing the MOZILLA_PKIX_ERROR_MITM_DETECTED error in Firefox.
Option 2 – Try to disable security.enterprise_roots.enabled
The next thing you can do if the first option didn’t work is to disable security.enterprise_roots.enabled which is an HTTPS certificate check on Firefox. Note that this is not recommended but you have to at least try in order to fix the error.
Open Firefox and then type “about: config” in the Firefox address bar and hit Enter.
After that, if an info message appears, confirm it.
Next, search for the security.enterprise_roots.enabled preference and once you found it, double click on it.
Then change its value to true and restart the Firefox browser once. This will import all the custom certificates from the other security software into Firefox. As a result, it will make sure to mark those sources as trusted and you won’t get the MOZILLA_PKIX_ERROR_MITM_DETECTED error.
