Stop C00002lA Fatal System Error- What is it?

C00002lA Fatal System Error is a blue screen of death error that may occur when you start your Windows NT 4.0 based computer. This error causes the screen to turn blue and the system also shuts down. The stop C000021A error message is displayed in the following format:

Stop c000021a {Fatal System Error} The session manager initialization system process terminated unexpectedly with a status of 0xc0000017 (0x00000000, 0x0000000) The system has been shut down.

Error Causes

The stop C000021A error occurs when either Crsrss.exe or Winlogon.exe fails. When the Windows NT kernel identifies that either of these processes has failed, it stops and the error code stop C000021A appears on the computer screen. Here are some of the underlying causes for the stop C0000021A error:

• The incompatible third-party program
• Hard disk issues
• Service pack installation has failed
• Mismatched system files have been installed
• Bad and invalid registry keys

Further Information and Manual Repair

To resolve the stop C000021A Fatal System Error on your PC try the following solutions:

• Remove Incompatible Third Party Programs

If the error occurred after you recently installed a new program, then it is advisable to remove that program. The error occurs due to the incompatibility of the program. To remove the program go to the start menu and click on the control panel. Now click on Add/Remove Program tab and double click on the program name that you recently installed and remove it from the list. Once removed, not reboot your PC. Reinstall a compatible program and run it. It is most likely to resolve the issue. However, if the stop C000021A error still occurs, then it means the problem is critical. It is related to the registry.

• Repair and Restore the Registry

This procedure is slightly long and tricky. To try it, you need to be technically sound. Here’s what you have to do: first create a parallel installation of Windows NT. Start your PC to the parallel installation and then open the Registry Editor. On the Registry Editor’s Windows menu click HKEY_LOCAL_MACHINE on Local Machine and then click Load Hive. Now type the path %systemroot%system32configsystem into the System hive of the prior installation. Then click open. Here you will be prompted to enter the name of the key, type TEST. Note the setting for the current DWord value in the preceding registry key. This is 0x1 and is denoted by CURRENT:Reg_Dword: 0x1. This value indicated that the Current Control Set for your original Windows NT installation corresponds to ControlSet001 in this window. Now if the value is 2, it indicated that the Current Control Set corresponds to ControlSet002. Now locate the following registry key: HKEY_LOCAL_MACHINETESTControlSetXXXControlSession Manager. XXX is the Current Control Set Value. And delete any pending file rename operation entries. Then click TEST hive and then click Unload Hive. After that again repeat the process, open the registry menu and click load hive, here type the path %systemroot%system32configSoftware to the Software hive of the prior installation and then click open. Now you type TEST 2 when you are prompted for the name of the key. Remove any pending file rename operations entries in the following registry keys: HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnce HKEY_LOCAL_MACHINETEST2MicrosoftWindowsCurrentVersionRunOnceEx Now click TEST2 hive and then click unload hive. Quit the Registry Editor and then restart your original installation. This will resolve the stop C000021A error.

If you have a dual monitor setup on your Windows 10 computer and you mostly use the second screen when you are presenting something, this makes the Taskbar completely unnecessary and is not really required. So if you are using your computer generally and do not want the taskbar on your second screen, read on as this post will guide you in disabling Taskbar on your second display. The good thing is, Windows comes with a built-in feature to disable Taskbar on your second screen or projector connected to your computer. In this post, you will be guided on how you can hide or disable the Taskbar from the second monitor in Windows 10. This post is coming in handy especially if you are using projectors or multiple displays. Refer to the steps given below to disable Taskbar on the second display in Windows 10. Step 1: Go to Settings and click on Taskbar from the left menu. Step 2: After that, scroll down to lo look for Multiple Displays. Step 3: Next, turn off the toggle labeled, “Show taskbar on all displays”. Note: After completing the steps given above, it will disable the Taskbar on all the secondary displays. Bear in mind that these settings will work only if you are running a second screen in Extended mode. Contrariwise, if you are in the Duplicate mode, this setting will not work but you can always set your Taskbar to Autohide so that it won’t be displayed.

On the other hand, if you are facing some issues in finding which screen is primary and which one is secondary, refer to these steps:

Step 1: Go to Settings and select System. Step 2: Next, from the left menu open Display. Step 3: From there, select the desired display and make it the primary one as required by your setup.

One of the most common Blue Screen of Death errors you can encounter on your Windows 10 computer is the Tcpip.sys Blue Screen error. The Tcpip.sys file is a driver file that is associated with the Transmission Control Protocol over Internet Protocol. When you see this kind of BSOD error, you may see any of the following error descriptions:

• IRQL_NOT_LESS_EQUAL
• KMODE_EXCEPTION_NOT_HANDLED
• PAGE_FAULT_IN_NONPAGED_AREA

Whichever error description you got, you need to do use the following instructions below as a reference to obliterate the Tcpip.sys Blue Screen error.

Option 1 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like Tcpip.sys Blue Screen 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.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.

Option 2 – Try resetting TCP/IP

In case you didn’t notice, the Tcpip.sys file is associated with the TCP/IP protocols in your computer system which is why resetting TCP/IP can help in resolving the Tcpip.sys Blue Screen of Death error especially when the TCP/IP has been modified.

• First, you need to type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option to open Command Prompt.
• After that, type the following command in the elevated cmd window and hit Enter:

netsh int ip reset

• Now reboot your computer after the command has been executed and check if it helped to fix the Blue Screen error.

Option 3 – Try to rollback your Network driver

If you have updated the driver software as of late and you suddenly got this BSOD error, you might have to roll back the device driver – in other words, switch back to the previous working version. To do that, follow these steps:

• Tap the Win + R keys to launch the Run window and then type in the “devmgmt.msc” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Next, select the driver entries that are labeled appropriately other than anything in the context of the WAN Miniport.
• Then select each one of them and double click to open a new mini window.
• After that, make sure that you’re on the Driver tab and if you are not, just navigate to it then click the Roll Back Driver button to switch back to the previous version of your Network adapters.
• Now restart your computer to successfully apply the changes made.

Option 4 – Try to update the Network drivers

You might also want to try updating all your network drivers in order to fix the Tcpip.sys Blue Screen error. To do so, here’s what you have to do:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• Under the Device Manager, you will see a list of drivers. From there, look for the Network Adapters and expand it.
• Then right-click on each one of the Network drivers and update them all.
• Restart your PC and see if it helped in fixing the BSOD error.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 5 – Try to disable both the Antivirus program and Firewall temporarily

There are times when antivirus programs and the firewall blocks a website that they consider to be malicious or even because of false-positive effects which is why you have to disable these programs temporarily as it might be the reason why you’ve encountered the error when trying to browse the internet.

In today's world setting up a LAN network or internet connection is no longer a daunting task that will require having a bachelor's degree in computer science nor a specialized technician. But even in the present-day environment issues and problems can occur. One of these problems is detecting or running a network at a slower 100MB speed instead of 1GB. Troubleshooting of this nature is somewhat more complex than your typical troubleshooting issue because several things including hardware could be involved in this particular problem but do not worry, we are here to back you up and guide you Setting up a home or small office network no longer requires a specialist technician to constantly monitor and optimize the LAN routers and connected PCs. As Windows networking has improved and new features have become available on the hardware, configuring a 1GB network should be as simple as connecting the LAN to a router that came with this capability. If however the network’s rated speed only gives 100MB, troubleshooting the issue is more complex. To find the problem, you’ll need to check the hardware devices, cable connections, and the software you are using to connect and manage the network.

Hardware checks

1. Check both connection jacks to see if it has any loose or frayed wires. If any of the wires are loose, it can be the cause of the performance issue. You should replace the cable if you discover damage to the connectors.
2. Inspect the entire length of the cable and check if the harness shows any clear signs of damage. A bent or damaged cable can reduce the amount of information it’s capable of transferring between the PC and LAN router. If you find any damage to the cable, replace it to restore your network speed.
3. Is the cable capable of transferring 1GB speeds? Different network cables support different network speeds. A Cat-5 cable will only provide 100MB transfers, while a Cat-5e or Cat-6 can support up to 10GB transfers. Check the cable’s labels to make sure you are using a Cat-5e or higher-rated data cable.

Now when the hardware issue is out of the way we can focus a little more on the software part.

Let's try the first easy solution, run Windows built-in troubleshooter

1. Click the Windows button and type Control Panel. Then select the top result.
2. If your Control Panel shows the Category View, change it to display Small Icons instead.
3. From the list of available applications, select Network and Sharing Center.
4. In your Network and Sharing Center, you can see the active network, set up a new network connection, troubleshoot problems, or change your adapter settings. Before making changes to your device properties, you can let Windows run a troubleshooter on your adapters to see if it can automatically fix your connection issues.
5. Click on Troubleshoot Problems from the Change Your Network Settings section.
6. In the Troubleshooter Application, scroll down and find the Network Adapter option.
7. Click on Run Troubleshooter to let Windows check your network adapter’s configuration for any issues.
8. Select the Ethernet Adapter you’re currently using from the list and click Next to proceed.
9. Wait for the process to complete and check the results. If Windows detects any issues, it will recommend a fix. However, if the configuration of your network adapters does not have any problems, you’ll see a message that Windows couldn’t detect any problems.
10. If there are any issues with the cable, the troubleshooter will detect the connection issue and request you replace the cable and connect it to your PC.
11. It can occur that even after inspecting the cable and you didn’t find any visible damage on the housing or connectors, it could still be faulty. Replace the cable with a new one and rerun the troubleshooter to see if the cable is working as required.

If the troubleshooter finished and you received a Windows Couldn’t Detect Any Issues result, you’ll need to verify your adapter’s speed settings.

1. In your Network and Sharing Center, select the Change Adapter Settings option from the left menu.
2. On the list of adapters, choose the one you’re using and click the Right Mouse Button to open the context menu.
3. Select Properties from the Context Menu to access your adapter’s settings.
4. On the Ethernet Properties window, you can enable or disable different features and install additional protocols. To change the device settings, click on Configure to continue.
5. This will open the Device Controller Properties window where you can check the status, make changes to the settings, find out information about the driver, or check historical events on the device. Select the Advanced tab to access the device settings.
6. On the Advanced tab, locate the Speed and Duplex setting.
7. The Auto-Negotiation option may cause network performance issues on certain Ethernet adapters and routers. The setting allows your adapter to change the speed settings according to the LAN configuration you connect to your PC. If you connect to different LAN networks regularly with different speeds, it can occur that the setting doesn’t update from 100MB to 1GB while switching.
8. Change the Value to match the network speed of the LAN you’re connecting to your PC and use the manual speed setting.
9. Click OK to apply the setting and test your network performance. If your adapter doesn’t have the 1GB setting available but you know the rating should go up to that speed, it could indicate that you aren’t using the right driver for the device.

If you don’t have the setting available or the device still only provides 100MB speeds after changing the Speed setting to a manual value, you may have to update the driver for the device.

1. On the Ethernet Properties Window, once again click on Configure to access the Device Properties Window. Then select the Driver Tab to access your driver details.
2. Select Update Driver from the available options.
3. On the Update Driver window, select the option to let Windows Search Automatically for Updated Driver Software.
4. Windows will connect to the internet and search for the latest drivers online. If a newer driver exists, Windows will download and install the driver for you. If you’re using the latest driver, Windows will inform you that no updated drivers are available.

So, what is Electron bot, and why it even matters if it is in the MS store. Electron bot is malware that somehow found its way inside MS Store via game clones of popular games temple run and subway surfer. This infiltration led to the infection of around 5000 systems over the globe in a very short period of time.

This malware is a backdoor that gives complete system control to the attacker. Any type of execution can be performed remotely in real-time. Usually, this kind of attack was aimed at a spread of click fraud over popular social media like Facebook, google, youtube, etc.

Primary goal

Electron Bot's primary goals in the ongoing campaign analyzed by researchers are:

• SEO poisoning – Create malware-dropping sites that rank high on Google Search results.
• Ad clicking – Connect to remote sites in the background and click on non-viewable advertisements.
• Social media account promotion – Direct traffic to specific content on social media platforms.
• Online product promotion – Increase store rating by clicking on its advertisements.

These functions are offered as services to those who want to increase their online profits illegitimately, so the gains for the malware operators are indirect.

Publishers that contain malware

For now, users may take note of the publishers who released confirmed malicious game apps using the following names:

• Lupy games
• Crazy 4 games
• Jeuxjeuxkeux games
• Akshi games
• Goo Games
• Bizzon Case

We have often talked about the security of your computer, we have been giving you tips and tried to explain how to best protect your computer from various attacks and malicious software. Today we will be talking about antivirus applications. Antivirus software has become the kind of a must-have in every computer in this day and age. When you think about it, our systems are connected to the internet most of the time if not always, and therefore kind placed in from the line of various cyber-attacks. Here antivirus software comes into focus, especially because it has evolved long from just a simple virus removal tool to full security suites. We will be going through the best of these applications in order to present both their good and bad sides and hope that we will help you in picking the right one for you. Remember, picking either one of the presented solutions is way better than not having one at all. The list is made from best down in our opinion so number one is highly recommended.

List of Best antivirus applications of 2021

1. BitDefender

   In our opinion the best overall security protection suite for this age and time. Bitdefender has cemented itself as number one a few years back and it holds that status even today. It has top-of-the-game virus protection, an incredible amount of features, safepay banking online protection and it is amazingly cheap. Its downside we could say is that it can be annoying sometimes, especially if you set it to maximum protection and paranoid mode. In this case, it will often ask what to do and how to behave leading to minor annoyances.

2. Norton antivirus

   Norton antivirus is well known to older computer users, this package has been around a long time and it is our pick for closest one to challenge top place because of its packed features. The number of features it has are really stunning and it comes also with great and maybe best-browsing protection of all candidates. It also has a backup tool bundled with it but the reason why it is in the second place is that it is taxing to the system and can have a real impact on computer performance. Great protection is important, but so it is working on it without slowdowns.

3. Kaspersky

   Another one of the old antivirus software on the list. Kaspersky Lab was once top tier antivirus software but it dropped down due to its high prices, later they have changed their pricing to be more in trend with other rival companies but many have switched to something else. Today it still packs one of the best antivirus engines with fast and configurable scans. It also has very impressive anti-ransomware features but sadly most of the things it just simply does for you leaving you to fully trust it since you cannot really configure much. It is not in step with new technologies and it is lacking some features like support for the Chrome browser that places it lower in our ranking.

4. Trend Micro antivirus

   The biggest sell point for this antivirus application is probably its ease of use and user-friendliness. It also packs a great antivirus engine and impressive anti-ransomware performance but sadly it comes with very limited configurability and somewhat lack of features comparing it with the top three entries. Never the less a very user-friendly application that you can configure without knowing any kind of tech talk, everything is laid out in simple English.

5. Avira

   Perhaps best known for its free version, Avira has a premium one that is well better worth than the free version. Strong suites of this software are mostly aimed at the internet with its great anti-phishing and web protection along with a low price for all of its features. Sadly in the domain of virus protection, there are some reports from independent websites that its antivirus engine is not so great, it will offer you moderate protection but not the best.

6. Webroot Secure Anywhere

   If you are on the lookout for software that has a great virus database and plenty of features but is also incredibly light weighted and fast then look no further, Webroot Secure Anywhere is an application for you, incredibly fast and incredibly small is a great solution for older machines. It keeps all of its databases up in the cloud and this feature among its great advantages is also its greatest disadvantage since if you are out of the internet you will not be able to have the latest virus definitions available to you making this tool very situational.

7. Avast

   Avast has many great protection features and it is very highly configurable. The firewall comes also in its premium edition and it offers great virus protection including a file shredder and awesome WI-FI inspector for an extra layer of security. This package would be higher on the list if it was not for its lack of WEB protection and its tool on the system resources.

8. Sophos home antivirus

   Lack of features and somewhat strange user interface are downsides of this software but on its positive side it has good antivirus engine and its user interface is very friendly. Where it shines though is in its price, for one affordable price you get protection for 10 devices making this option a great choice for anyone wanting to protect more devices or just use a single license for the whole family.

9. ESET antivirus

   Greatly configurable antivirus software with tons of options and very light on system resources makes ESET one of the best out there. Virus engine and database is also top tier but some testing labs have reported that protection offering is not really what it is advertised and if we talk about its strong suite of a great many options and configurations it is at the same moment its downside since it is not very friendly to novice and beginner users.

10. McAfee antivirus

    McAfee antivirus comes in its package with unlimited VPN service and if we take look at the top tier pricing plan it is a great investment. Sadly for its entry-level price, it covers only a single device and it was reported that it packs little outdated virus engine if we compare it with its rivals. Nevertheless, it still offers good virus protection and if you take into account the VPN that comes with it, it can find its users.

Conclusion

No matter which antivirus you choose you will not go wrong, after all any protection is way better than none.

Error 0x8004210A - What is it?

0x8004210A is a typical POP3 email error message. This error may sometimes occur when you try to check your Post Office Protocol 3 (POP3) email account. 0x8004210A error code hampers your ability to both send and receive e-mails on your Outlook account. Error 0x8004210A is displayed in any one of the following formats on your PC:

The operation timed out waiting for a response from the receiving (POP) server 0x8004210a Task 'SMTP server name - Sending and Receiving reported error' (0x8004210A): 'The operation timed out waiting for a response from the receiving (POP) server. If you continue to receive this message, contact your server administrator or Internet service provider (ISP).'

Error Causes

Error 0x8004210A occurs due to several reasons. However, some of the most common reasons include:

• Wrong port number for the POP incoming server
• Your connection to the mail server is too slow
• Incoming and outgoing emails are being scanned and stopped by an antivirus installed on your system
• The Outlook send and receive job is being blocked by Firewall
• You are sending and receiving large series of emails or large email attachments
• Registry issues

No matter what the cause of this error is, to resume email communication via Outlook and to ensure your work productivity is not affected, it is recommended that you resolve this 0x8004210A error code on your PC immediately.

Further Information and Manual Repair

To fix error 0x8004210A, here are some of the most efficient and easy manual methods that you can try:

Method 1

If the cause of the error is related to the internet connection then here’s what you need to do. Try freeing up your internet connection by closing any other online activities in progress or downloads being carried on your system.

Method 2

Try to increase your server time-out periods. To do this, go to the Outlook File menu and choose account settings. Now double click on your email account and more settings. Now click advanced and increase your server timeout period to resolve.

Method 3

If you are trying to send or receive large and heavy emails on your Outlook account, the error 0x8004210A may pop up. This happens because when transferring heavy files the email account automatically locks until the task is complete, however, if it takes more time the next Send and Receive job starts while the first one is still not complete. In such an event, the email server then times out and shows you the error. Therefore to resolve, you will have to show patience. Simply wait for the large email to be sent or received before you start sending another email.

Method 4

If the antivirus installed on your system is the reason for the error pop up, then disable it for a while until the operation is complete. Then enable it once the task is performed successfully.

Method 5

Similarly, if the Firewall installed on your system is preventing Outlook from reaching your mail server, then simply disable the Firewall to resolve.

You probably heard about switches for LAN but not a lot of people heard about KVM switches. So what exactly is KVM switch?

If we look at the name, it is a shortcut for Keyboard, Video & Mouse and the original idea was to have multiple computers but one keyboard, mouse, and monitor. These peripherals would be connected to the KVM switch and other computers could all use one set of these on the fly when needed.

The technology behind the switch is a little interesting since it will actively fake signals to other computers that are not using peripherals. Once they are switched to them the transition is smooth and not noticeable. In old days these switches were more important than today since on every mouse or keyboard disconnection you had to reboot the computer, and although today that is not the case CPU will still detect disconnection and on the next connection it will run through the ID of the device and try to use the existing driver and if peripheral was connected in other USB port, it will install the same driver but connect it to the new USB port.

This type of reconnection can slow down work and place unnecessary load on the CPU so that is why KVM will fake connection in order to make switching externals on the computer smooth and in nick of a time.

Modern KVM switch

These days modern KVM switches will offer you more options than just being able to switch between keyboard, mouse, and monitor. Modern switches now offer Lan, audio, and many more various options.

There are also different kinds of switches offering you only one option, like for example just a Video switch that will let you use one monitor on three computers and many more other specialized options.

Software switches

So far we talked about Hardware switches, a real device being able to take peripherals into it and switch computers on the fly. On the other line, we have software switch solutions that will have specific software installed on all computers and have it run at all times, and switching between them will be through specific software.

There are two very good and main advantages of using software solutions instead of a hardware one. First, of course, is the price, since the most popular Synergy is an open-source solution, completely free of charge. The second big advantage is that software switch is not limited to how many computers can you use. Hardware switches tend to go to a large number like 16 but if you have a large cluster of computers over a LAN, let's say 30 then the box solution might be difficult.

On the other hand software solution will switch only keyboard and mouse since each other computer will have to have some screen on it in order to work. Both solutions have their strong advantages and disadvantages and it is up to you to choose one that best suits you.

Conclusion

If you are multitasking with a lot of computers or just need your peripherals from time to time to connect to another machine then the KVM switch is something that you might find the use of. Just be aware that if you go for some cheap switch you might experience some lag on your peripherals, but if that is not a concern you can get hardware one for as low as $50 USD.

If the Sleep option is missing from the Power Menu then this could be caused by the power settings, local group policy configuration, etc. in your computer. Based on the reports of users who experience the same problem, the issue occurred after they’ve updated or upgraded their Windows 10 computers. As you know, the sleep mode is quite useful in certain cases and is utilized by most users. If you put your computer in sleep mode, it actually minimizes the power usage of your computer while at the same time keeps your current session running. So if sleep mode is suddenly missing, then that could be a problem but worry not for this post will give you possible fixes to resolve the issue. Make sure to follow each one of them carefully to achieve good results.

Option 1 – Check the Power settings

As mentioned, one of the reasons why the Sleep option is missing could be the power settings in your computer. To check this possibility, make sure that you’ve enabled the sleep mode in the Power options setting window. How? Refer to these steps:

• First, go to the Start menu, and from there open Control Panel.
• Next, set the View by Large icons and select the Power Options.
• After that, click on the “Choose what the power buttons do” option on the left-hand side.
• Then click on the “Change settings that are currently unavailable” option and make sure that Sleep is checked under the Shutdown settings.
• Afterward, click on Save changes.

Option 2 – Modify the Local Group Policy

If the Power setting isn’t the cause of the problem, then you might want to check the Local Group Policy and modify it. There is a dedicated policy for showing the sleep option in the power menu and if this policy is disabled, then it’s no wonder why you don’t see the sleep option in the power menu. To change this policy, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• Then type “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• Next, navigate to this path: Computer Configuration -> Administrative Templates -> Windows Components -> File Explorer
• Look for the “Show sleep in the power options menu” option from the right-hand side pane and double click on it.
• Now change it to Enabled and click on the Apply and OK buttons to save the changes made and restart your computer.

Option 3 – Try to turn on Standby

Standby, also known as InstantGo, is a feature in Windows 8 and 10 that allows users to maintain network connectivity after a computer has been put into sleep mode. Thus, if this feature is disabled, it can cause the Sleep option to disappear from the power menu. To turn it on, follow these steps:

• Tap the Win + R keys to open Run.
• And type “Regedit” in the field and tap Enter to open the Registry Editor.
• Next, navigate to this path: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlPower
• From this path, look for the “CsEnabled” key on the right-hand side of the pane and double-click on it.
• Set its value to “1” and click OK to save the changes made.
• Now reboot your PC.

Note: If you were not able to find the CsEnabled key, then this indicates that your computer does not support the Standby feature. And if that’s the case, proceed to the next given option below.

Option 4 – Try to install a Video Card driver

On the other hand, some users reported that the problem was caused by the video card driver. And if your computer lacks the video adapter driver, it can also cause the same problem. Windows 10 typically install the video card driver on its own, however, there are rare cases when it doesn’t which is why you have to do it yourself manually. All you have to do is go to your manufacturer’s website and look for the video card driver, download it and then install it. Once you’ve installed the video card driver, reboot your computer and check if it has fixed the problem.
