Remove ChatZum from Windows

ChatZum is a Potentially Unwanted Program that installs a Toolbar into your browser. This program allegedly allows users to zoom in on photos without clicking on them, however, upon further research, it was discovered that this function does not work on the latest version of browsers.

From the Author: ChatZum is a Browser add-on (toolbar) that enables its users to hover over images in Major Social network's websites and view a larger version of an image.

While installing this toolbar will track user web browsing sessions and will record website visits, clicks, and sometimes even personal information. This information is later used to display targeted ads to the user. To allow easier user tracking, the program changes the browser home page and default search engine to Nation Search Advanced, which injects additional advertisements and tracks user activity.

Several anti-virus applications have marked this program as Potentially Unwanted, and it is not recommended to keep it on your computer, especially considering the fact it will most likely not work on your browser.

About Potentially Unwanted Applications

If you have ever installed a free application or shareware, chances are high that the computer will get installed with a bunch of unwanted applications. A Potentially Unwanted Program, also called PUP, in short, is actually software that contains adware, installs toolbars, or has got other hidden objectives. These types of programs are generally bundled up with a free application that you download from the internet or may also be bundled inside the custom installers of many download websites.

PUPs aren’t always viewed as “pure” malware in the strictest sense. A fundamental difference between PUP and malware is distribution. Malware is normally dropped by silent installation vectors like drive-by downloads while PUP gets installed with the consent of the computer user, who knowingly or unknowingly approves the PUP installation on their computer system. But, there is no doubt that PUPs remain bad news for PC users as it could be quite dangerous to your computer in many ways.

The damage PUPs can do

The unwanted programs after installation display numerous annoying pop-up ads, trigger fake alerts, and sometimes even forces a computer owner to pay for the software. PUPs that come as browser add-ons and toolbars are commonly recognizable. These toolbars alter your homepage and your search engine in the installed web browser, track your web activities, modify your search results with redirects and sponsored links, and eventually slow down your browser and diminish your browsing experience.

Potentially unwanted programs use aggressive distribution methods to get onto your computer. The worst part of setting up a PUP is the adware, spyware, and keystroke loggers that could lurk inside. Even if the PUPs really aren’t inherently malicious, these applications still do practically nothing good on your PC – they’ll take valuable system resources, slow down your PC, weaken your computer security, making your PC more vulnerable to malware.

How to avoid ‘crapware’

• Read the EULA thoroughly. Look for clauses that state that you have to accept advertising and pop-ups or bundled applications from the company.
• Always opt for the custom if you’re offered an option between “Custom” and “Recommended” Installations – never ever click Next, Next, Next thoughtlessly.
• Use a good anti-malware application. Try Safebytes Anti-malware which can find PUPs and treat them as malware by flagging them for deletion.
• Be alert if you download and install freeware, open-source applications, or shareware. Do not ever install software applications that seem shady or malicious.
• Always download applications from the original website. The majority of PUPs find their way onto your laptop or computer is via download portals, so steer clear of it altogether.

Remember the fact that even though PUPs could potentially cause damage and hinder the proper functioning of the PC, they can’t enter into your system without your consent, so be alert not to provide them with it.

Fix NO_USER_MODE_CONTEXT in Windows

If you have encountered the NO_USER_MODE_CONTEXT Blue Screen error when using your computer, read on as this post will walk you through a couple of suggestions you can try to resolve this Stop error. This kind of Blue Screen error can occur when a program is trying to leverage the use of a system driver but fails to do so. Some of the common causes of this BSOD error are incompatible or corrupted drivers, incorrect configuration of entries in the Registry, damaged memory locations, malware infection, and many more. In addition, this Stop error does not often occur and indicates that an attempt to enter user mode with no context was made. If this is the first time you’ve restarted your computer after you’ve installed additional hardware, you have to remove the hardware and then restart your computer once again and then check the Microsoft Hardware Compatibility List to confirm that the hardware and its drivers are compatible with your operating system. If it doesn’t help, you can check out the given suggestions below to fix the NO_USER_MODE_CONTEXT Blue Screen error in Windows 10.

Option 1 – Try to update or rollback your device drivers

The first thing you can try to fix the NO_USER_MODE_CONTEXT Blue Screen error is to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

Open the Devices Manager from the Win X Menu.
Then locate the device drivers and right-click on them to open the Properties. Note that the main drivers that might be the cause behind the NO_USER_MODE_CONTEXT Blue Screen error will be listed under the “ID ATA/ATAPI controllers” section as well as the “Storage controllers” section.
After that, switch to the Driver tab and click on the Uninstall Device button.
Follow the screen option to completely uninstall it.
Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can also directly download the relevant drivers of your computer from the manufacturers’ website. So if you have an SSD, the issue might be due to an old storage driver.

Option 2 – Try running System File Checker or SFC scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.

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.

Reboot your PC.

Option 3 – Try running the Memory Diagnostic Tool

The Memory Diagnostic tool in windows can help resolve the NO_USER_MODE_CONTEXT Blue Screen error by checking and automatically fixing any memory-based issues. To run it, refer to these steps:

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
Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select your preferred option, your computer will restart and check for memory-based issues. If it finds any issues, it will automatically fix them.

Option 4 – Perform System Restore

First, 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.

Common Outlook Errors

Most Common Microsoft Outlook errors

When you have a program, you know before you even start to use it or even know how that you are going to have problems with it. There are always going to be error messages and things that don’t work on any program you buy or download; guaranteed. Even some of the most famous program developers in the world make mistakes from time to time and it is a small price to pay for the programs you get and that is a fact. Microsoft Outlook is like any other program; it has its errors. Here are some of the most common errors for Microsoft Outlook on your computer.

1. Problem receiving emails

Sometimes you can be waiting on really important emails. It is really infuriating when you know that they have been sent, however every time you check your email box, there is nothing there! Your inbox is empty and your patience is wearing thin, so could it possibly be an error with Microsoft Outlook? There is a high probability that this is the problem. The program can be a bit slow on receiving emails sometimes, often even by days. This can be caused by any number of things, from having too many emails coming through or having too many emails in your inbox. If you click ‘send and receive’ at the top, it should speed up your emails coming through, however, so give that a try if you’re waiting on anything to come through. If this doesn’t work, however, your inbox may be full. Try permanently deleting some useless messages and then click ‘send and receive’ again. All your emails should come through then!

2. General slow performance

Outlook, while it has its advantages, can often be very slow. It is probably slower than some other email programs that require a browser but it is quicker to access, which may make up for this fact. However, sometimes sluggish performance can be really irritating, so it may be wise to try and fix it if you can. One of the reasons it may be acting slow is if you have too many other Windows applications open. Applications that may interfere with your Outlook’s speed could be anything from Microsoft Word to Windows Live Messenger. If any of these are open, try closing them and see if that helps with the speed problem.

3. Corrupt files

.dbx files are not accessible by Microsoft Outlook. Therefore, they can cause problems with your emails if you have them within them. To solve this problem, you may have to delete all of your attached email accounts and then reattach them before you can open your emails again. These corrupt files can also cause you to be unable to delete emails. You will need to transfer these deleted corrupt files into a separate deletion folder as this is usually caused by the folder being corrupt. Of all the other most frequent problems with Microsoft Outlook, however, this is probably the least likely to happen, which shows how few problems there actually are with this application after all that!

Conclusion

So there are the most common problems with Microsoft Outlook! Not much wrong at all, is there?

Experiencing Error Code 36, We Have A Solution!

Error Code 36 – What is it?

This is a common Device Manager Error Code that users encounter. It is commonly found on all Windows 2000 and later versions of Windows operating systems. Error Code 36 is usually prompted by the following message:

"This device is requesting a PCI interrupt but is configured for an ISA interrupt (or vice versa). Please use the computer's system setup program to reconfigure the interrupt for this device. (Code 36)"

Solution

Error Causes

Error Code 36 occurs when there is a failure in IRQ translation due to your Windows operating system getting corrupted. This is caused due to a number of triggers, such as:

An excess of startup entries
Errors in registries
RAM or hardware failure
Excessive unnecessary installed programs
Malware or spyware

When programs are removed excessively, some programs are not removed completely and create problems in your computer’s registry.

Also, due to the presence of malware and spyware and other causes mentioned above, your computer registry builds up errors with the time that leads to slowing your PC, time lags, and even result in crashes and freezes.

Error Code 36 can cause internal and external components to malfunction or experience time lags such as DVD drive or printer and hence can severely affect your entire PC.

Further Information and Manual Repair

Error Code 36 is a severe PC error and any attempt at fixing the error must be approached with extreme caution for your PC to start functioning properly again. Here are two methods to fixing your PC.

Method 1 – Change IRQ reservation settings

Changing the IRQ reservation settings is the best way you can rely on to fix the error code. You can do this by changing the BIOS settings of your PC.

The BIOS stands for ‘Basic Input/Output System’ and is the program of your PC’s microprocessor that allows your PC to boot after you switch it on.

Caution needs to be exercised before changing the BIOS settings of your PC. This is because every PC’s BIOS version differs from another and any wrong attempt to change the settings may make matters worse.

It is therefore recommended to refer to hardware documentation that you received with your PC or motherboard and check for the model number and details of your PC’s motherboard.

Only after you have checked and confirmed all the details, should you use the specific BIOS settings required to configure your IRQ reservations?

Method 2 – Install DriverFIX

Error Code 36 isn’t an easy error to remove.

While changing the BIOS settings can work to restore your PC, it may create a whole lot of inconvenience for finding the time and effort to check the hardware documentation details and attempting to change the specific settings and especially, if your PC does not support the options to change IRQ reservations.

Given the high risks of fixing such an error, you can also install software that enables you to fix your slow PC at the click of a few buttons.

Programs such as DriverFIX can enable you to download and replace your outdated drivers with new updated ones without you having to look for them. It will detect which drivers to download based on your PC’s motherboard version from the program’s database and can get rid of error code 36.

Click here to download DriverFIX and remove error code 36 and any other type of Device Manager error from your PC.

Fix Windows 11 Black Screen Error

A black screen error inside Windows 11 is a typical screen turning to solid black without any error message. This can be very annoying since it can randomly appear out of nowhere and it will appear while you are using the computer. Worry not, this is not a serious error and we have several solutions for it, so please keep reading and try them as presented in order.

Restart graphic driver

This is the first thing to check if the issue is due to software or driver malfunctioning, there is a shortcut for rebooting graphic driver inside Windows 11. Press WINDOWS + CTRL + SHIFT + B to reboot the graphic driver and see if this fixes the issue. A beep sound should be heard during this process and the screen should turn back to normal.

Check connections

Sometimes the screen can go black due to a faulty connection or cable. If you have it at your hand try a different cable or slightly and gently nudge the existing one to see will screen flicker. If you are on a laptop try gently moving the lid from back to front and pay attention to the screen. If screen flickers or picture returns with this method, cable or connector needs to be replaced.

Clean your computer

The black screen can be because the computer is overheating. If this is the case either fan inside is not working properly or there is a lot of dirt and dust that needs to be removed so airflow can be established again for proper cooling. We have an article on errortools.com on how to properly clean your PC but if you are not technical enough maybe the best solution would be to call someone who is or to take the PC to service for cleaning.

Change The Projection Settings

Press WINDOWS + P to open projection settings, check to see if PC is set to PC screen only. If any other option is selected change it to PC screen only since this can cause random black screen issues.

Uninstall latest updates

If this problem has started to manifest itself during the latest update, go to setting and roll back from the latest update to fix this issue.

Scan system for malware

The black screen can also be caused by various viruses and malware. IF you have anti-virus software, run a full system scan to check it for malware. If you do not have one, download a free one and run a system scan, we recommend Bitdefender.

How to set up the Autodesk Network License Manager on a Mac.

Note: The Autodesk License Server Manager (version 11.16.2.0) is supported only on the following Mac operating systems:

Apple macOS High Sierra 10.13
Apple macOS Sierra 10.12
Apple Mac OS X El Capitan 10.11

Download Autodesk Network License Manager version 11.16.2.0 for Mac
- Download the nlm11.16.2.0_ipv4_ipv6_mac_universal.tar.gz file to the Desktop.
To install the Autodesk Network License Manager:
- Double click on nlm11.16.2.0_ipv4_ipv6_mac_universal.tar.gz to unpack the installer package.
- After unpacking nlm11.16.2.0_ipv4_ipv6_mac_universal.pkg, will be /Downloads/adlm/FLEXnet folder.
- Double click on nlm11.16.2.0_ipv4_ipv6_mac_universal.pkg to start installation and follow the installation wizard.
- The license server will be installed in /usr/local/flexnetserver/ directory.
Change permissions for /usr/local/flexnetserver/ directory to 777

Open Terminal (located in /Applications/Utilities/Terminal) and enter the following command:

sudo chmod -R 777 /usr/local/flexnetserver

Note: Administrator password may be asked. While typing no characters are shown, just type out the password and hit return key.
Note: To start the license server only with elevated permissions (using sudo command), change permissions to 755 instead of 777.

Create /usr/local/flexnetserver/licenses directory for network license file location

sudo mkdir /usr/local/flexnetserver/licenses

Find the license server Host Name and Host ID.
Generate the Network License File in the Autodesk Account
- Once the license file is generated, make sure it has a .lic extension (e.g. adsk_license.lic) and is in a plain text format and place it in /usr/local/flexnetserver/licenses directory

Note: In this article we will refer to adsk_license.lic as network license file name. Feel free to change the actual name of the license file, but make sure to reflect the new name when using the commands below.

Create a debug.log file in the /usr/local/flexnetserver/ directory using the following command:

touch debug.log

To start the Network License Server use the following command:

/usr/local/flexnetserver/lmgrd -c /usr/local/flexnetserver/licenses/adsk_license.lic -l /usr/local/flexnetserver/debug.log

Note: If folder permissions for /usr/local/flexnetserver/ are set to 775, then use sudo command to start the server. For example:

sudo /usr/local/flexnetserver/lmgrd -c /usr/local/flexnetserver/licenses/adsk_license.lic -l /usr/local/flexnetserver/debug.log

To obtain license server status enquiry:

/usr/local/flexnetserver/lmutil lmstat -a -c /usr/local/flexnetserver/licenses/adsk_license.lic

To stop the license server:

/usr/local/flexnetserver/lmutil lmdown -q -force

Alternatively, run ps command to obtain process ids for lmgrd and adskflex and then kill those processes:

ps -ax | grep lmgrd
ps -ax | grep adskflex
kill -9

(provide process ids obtained by previous commands individually)

How to set up the Autodesk Network License Manager on Linux.

Note: The Autodesk License Manager (11.16.2.0) is supported only on the following Linux distros:

Red Hat® Enterprise Linux® 7
Red Hat Enterprise Linux 6
SUSE Linux Enterprise 12
SUSE Linux Enterprise 11

See System Requirements for the Network License Manager

To configure the license manager use the following steps:

Download Autodesk Network License Manager v. 11.16.2 for Linux from this link
- Download the nlm11.16.2.0_ipv4_ipv6_linux64.tar.gz file to your desktop.
To install the Autodesk Network License Manager run following command as root.
- tar –zxvf nlm11.16.2.0_ipv4_ipv6_linux64.tar.gz
- rpm -vhi nlm11.16.2.0_ipv4_ipv6_linux64.rpm
- The license server will be installed in /opt/flexnetserver/ directory.
Find the license server Host Name and Host ID

To obtain the license server system hostid run the following command

/opt/flexnetserver/lmutil lmhostid From the command output note the hostid in quotes, if the system has two active NIC cards, select the first MAC address. lmutil - Copyright (c) 1989-2018 Flexera. All Rights Reserved. The FlexNet host ID of this machine is "000c297949e0"

To obtain the license server system hostname run the following command

/opt/flexnetserver/lmutil lmhostid hostname From the command output note the hostname of the license server. mutil - Copyright (c) 1989-2018 Flexera. All Rights Reserved. The FlexNet host ID of this machine is "HOSTNAME=Centos7.localdomain"

Generate your Network License File in Autodesk Account
- Once the license file is generated, make sure it has .lic extension (e.g. adsk_license.lic) and place it in /opt/flexnetserver/licenses directory. If the directory doesn't exits, create it with this command: sudo mkdir /opt/flexnetserver/licenses

Note: in this article we will refer by adsk_license.lic your network license file name.

To start the Network License Server
- /opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/adsk_license.lic -l /opt/flexnetserver/server_log.log
To obtain license server status enquiry
- /opt/flexnetserver/lmutil lmstat -a -c /opt/flexnetserver/licenses/adsk_license.lic
To stop your license server service
- /opt/flexnetserver/lmutil lmdown -q -force
- alternatively you can also run ps command to obtain process ids for lmgrd and adskflex and then kill those processes
  - ps -aw | grep lmgrd
  - ps -aw | grep adskflex
  - kill -9 (provide process ids obtained by previous commands individually)
To start the license server automatically after the system reboot
- Open /etc/rc.d/rc.local script as root and enter license server start up command in it.

touch /var/lock/subsys/local /opt/flexnetserver/lmgrd -c /opt/flexnetserver/licenses/adsk_license.lic -l /opt/flexnetserver/server_log.logNote: To ensure that the script will be executed during boot, run following command as root. chmod +x /etc/rc.d/rc.local

Make sure that all necessary ports are open:

lmgrd.exe needs ports 27000 to 27009.
adskflex.exe needs port 2080.

Note: Errors may occur if the network license file is corrupt or in the case of a combined network license it has incorrectly combined licenses. To learn more about combining licenses, see Combining License Files for Multiple Autodesk Products. Use the License File Parser to verify that the license contains the appropriate products and FLEXnet feature codes and does not display an error

Verify that TCP ports (2080, 27000-27009) used by Autodesk Network License Manager are not blocked by Firewall.

The FLEXlm® based version uses the following incoming ports:

TCP ports 2080 (for the adskflex vendor daemon)
TCP ports 27000 to 27009 (for the lmgrd master daemon, which uses the first open port in the range)

Note: If these port addresses are restricted by a router or firewall software, users on the remote side of the router will not have access to licenses controlled by the Network License Manager.

Verify that the client computer is configured with the correct license server name or IP.

Windows:

Clear license server information from the system registry.

Type regedit in the Windows Search box and hit Enter key.
Select the following registry key

[HKEY_CURRENT_USER\SOFTWARE\FLEXlm License Manager]

As the key is selected, in right panel ADSKFLEX_LICENSE_FILE will be visible.
Right click on the key and delete it.

Specify the license server in ADSKFLEX_LICENSE_FILE system variable

Go to Start > Control Panel > System and Security > System.
Select Advanced system settings.
On the System Properties dialog, click Environment Variables.
Under System Variables, click New.
Enter ADSKFLEX_LICENSE_FILE for the variable name and 2080@SERVER_NAME _OR _IP for the variable value.

Note: the license server information most often is recorded in LICPATH.lic file and can be verified there too. ADSKFLEX_LICENSE_FILE system variable supersedes LICPATH.lic. Thus, setting the system variable is preferable when this error is seen.

If the license server is on a VPN or a remote network set the FLEXLM_TIMEOUT environment variable:

Go to Start > Control Panel > System and Security > System.
Select Advanced system settings.
On the System Properties dialog, click Environment Variables.
Under System Variables, click New.
Enter FLEXLM_TIMEOUT for the variable name and 5000000 for the variable value.
Click OK to save the setting.

Note: if needed the variable value can be increased to 10000000.

Mac/Linux:

Specify the Autodesk Network License server information in $HOME/.flexlmrc file.

Use a text editor to create a flexlmrc.txt file and save it in Plain text format (In TextEdit on Mac: Format - Make Plain Text) on desktop. The file content should look like this, except with the name or IP address of the license server.

ADSKFLEX_LICENSE_FILE=@SERVER_NAME _OR _IP

If the license server is on the same machine as the Autodesk software, use localhost as the license server name. Thus, the content of flexlmrc file could look like this:

ADSKFLEX_LICENSE_FILE=@localhost

Note: On firewall restricted network or when accessing the license server via VPN, need to include TCP port/s (usually 27000 or 2080) into Autodesk License Server service as follows: ADSKFLEX_LICENSE_FILE=2080@SERVER_NAME _OR _IP

Once flexlmrc file is created move it to user's $HOME folder as follows:

Open a Terminal window
Type open ~ (Mac) or nautilus ~ (Linux) to open $HOME folder
Drag and drop flexlmrc.txt file from Desktop to the home folder.
To make the file a configuration file, rename it to .flexlmrc (please note . [DOT] in front of the file name) by running the following command:

mv flexlmrc.txt .flexlmrc (Mac)
mv flexlmrc .flexlmrc (Linux)

Verify that the license server information registered with the product is correct (versions 2020 and later only)

In versions 2020 and later, the license server information is registered with the AdskLicensing service running locally on the workstation. When changing to a new license server, the old server information may still be registered with AdskLicensing and result in the error above, if this is not appropriately updated. See the below steps to solve this:

Click the Start menu and type cmd.
Right-click on the Command prompt and choose "Run As Administrator."
In the Command prompt, run the following command, followed by ENTER:

"C:\Program Files (x86)\Common Files\Autodesk Shared\AdskLicensing\Current\helper\AdskLicensingInstHelper.exe" change -pk PRODKEY -pv VER.0.0.F -lm "" -ls "" -lt""

Note:

Replace PRODKEY with the product key correspondent to your product(s). See Look Up Product Keys for the full list.
Replace VER with the version you are using. E.g. 2020 for AutoCAD 2020.
Repeat this step for each software you need to reset.

Open Registry Editor (Start > type regedit > ENTER).
Navigate to HKEY_CURRENT_USER\Software\FLEXlm License Manager.
On the right-side, verify of the ADSKFLEX_LICENSE_FILE key exists. If yes, remove it (right-click > Delete).
Run the software again.
Select Multi-user in the Let's Get Started screen.
Follow the steps to connect to your license server.

How to Fix Tcpip.sys Blue Screen Error in Windows 10

If you have received a BSOD error message that says, “Tcpip.sys”, read on as this post will show you how you can fix the problem. The “Tcpip.sys” means Transmission Control Protocol over Internet Protocol. It is a library of a set of rules that are used to interconnect different devices all over the internet. The Tcpip.sys file is a driver and if a BSOD error message includes this one, it could only mean that the driver file is corrupted or incompatible with your system or there are some conflicting programs installed in your computer. To fix this error, you can try the following workarounds. Make sure to carefully follow each one of them.

Option 1 – Check for conflicting or incompatible programs by putting your PC in a Clean Boot state

As mentioned, the “tcpip.sys” BSOD error might be caused by some problematic programs that clash with your existing operating system. Several users reported that numerous programs that are supposedly designed to enhance computer performance are causing conflict in the system instead. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.

Log onto your PC as an administrator.
Type in MSConfig in the Start Search to open the System Configuration utility.
From there, go to the General tab and click “Selective startup”.
Clear the “Load Startup items” checkbox and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
Next, click the Services tab and select the “Hide All Microsoft Services” checkbox.
Click Disable all.
Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)

After putting your PC in a Clean Boot State, try creating a system restore point and see if the problem still occurs. Clean Boot troubleshooting is designed to help you isolate the problem. For you to execute a clean boot troubleshooting, you must do a couple of actions (the steps are given above) and then restart your PC after every action. You might have to disable one third-party app after the other to really isolate the issue. And once you’ve narrowed down the problem, you can either disable the third-party app that’s causing the problem or remove it. Note that you must switch your PC back into the Normal Startup mode after you’re done troubleshooting the problem. Here’s how you can do it:

From the “Start” menu, go to System Configuration.
After that, switch to the General tab and click the option for “Normal Startup”.
Next, go to the Services tab and clear the checkbox for “Hide all Microsoft services”.
Then find and click “Enable all” and if prompted, you have to confirm.
Afterward, go to the Task Manager and enable all the Startup programs and confirm the action.
Restart your PC when prompted.

Option 2 – Disabling Antivirus Software

There are cases when the “tcpip.sys” BSOD error is caused by the antivirus program installed in your computer that’s blocking some essential operations. Because of this, the operating system fails which throws up the BSOD error. As you know, the antivirus program is designed to protect the computer and monitor every action in the system. However, there are instances when the antivirus program gives false positives and shuts down some modules even if it’s harmless. So this could be the case for the “tcpip.sys” error. To verify if the problem is indeed caused by the antivirus program in your computer, you need to temporarily disable it. After you’ve disabled it, restart your PC and then check if the problem’s fixed or not.

Option 3 – Try to update all your Drivers

From time to time, drivers get corrupted or outdated so it’s no surprise that they conflict with the operating system and cause errors like the “tcpip.sys” BSOD error. To fix the problem, you need to update all your drivers especially the network driver since the “tcpip.sys” error is closely related to this driver. Follow the steps below to update your drivers.

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’s name and select “Update Driver Software” or “Uninstall”. And if you find any “Unknown device”, you need to update it as well.
Select the “Search automatically for updated driver software” option and then follow the instructions to complete the process.
Restart your PC.

Note: You also have the option to go directly to the website of your graphics card manufacturer and check if there’s a new update – if there is, download it. After that, you could also check if there’s a new update of the game you’re getting the issue of the black bar.
