If you know of any remedy, please let me know. Thanks a lot. 

Have you ended up reading this article because the above question relates to you somehow? In other words, have you come across tcpyp.sys BSOD error and looking for a solution to fix it?

Well, you are reading the perfect guide so keep reading. In this guide, we will explain how to overcome this annoying error for good.

Introduction to Tcpyp.sys 

In a nutshell, the BSoD error is an MS Windows error screen. This specific error seems to signal system problems and the possibility of a crash. Because these vital notifications were presented on a blue screen, the phrase “blue screen” was coined.

The hardware of the system, system’s temperature, timing error, resources, faulty registries, and viruses all contribute to BSOD. The Blue screen error acts as a warning to prevent additional harm to the computer and system.

A blue screen of death (BSoD) causes Windows to freeze and needs a reboot to continue operating.

The blue screen of death has become less prevalent nowadays. That is because modern-day operating systems have improved their ability to handle several faults without interruption.

A stop error is another name for the BSoD. Also, tcpyp.sys is just one type of BSoD you might receive.

PS: if you are experiencing the issues like 0x0000000a Blue Screen Error, here are the top solutions for you.

The Following Are the Four Major BSoD Components:

  • The error message it delivers
  • What memory modules are loaded
  • What modules are unloaded with no noticeable error
  • Existing status of the kernel-debug

What Does BSoD Look Like?

With a combination of hexadecimal numbers and text, BSoD error codes offer related driver info and troubleshooting recommendations. Before restarting, users should make a note of this information.

Users should also double-check that their hardware is installed correctly and reverse any recent hardware or software changes.

Memory dumps are also fallen into BSoD problems. The system’s memory is dumped and stored to a hard disk file for debugging when a system fails. Because the OS has become unable to recover from kernel-level failures, the BSoD fault details are presented.

The Following Steps Become Useful when Reading BSoD Error Codes:

  • Perform a right-click on the start menu and choose the option called “Computer“.
  • Then, you should choose the option called “Manage“.
  • When you are in the window labeled “Computer Management,” choose “Event Viewer” to proceed.
  • In the event log data, you can find the actual reason for the BSOD.

The Composition of a BSoD Error Message

The BSoD cause is indicated by the name of the BSoD file (.SYS extension). Tcpyp.sys is only one example of that. If the name of a BSoD file cannot be found, use a driver updater tool.

Such a tool will become exceptionally handy to search, downloading, and updating the drivers installed on the device.

Problems with your computer’s hardware or difficulties with its hardware drivers are the most common causes of blue screens. Issues with low-level applications operating in the kernel may sometimes cause them.

Apps that aren’t designed to fix blue screens are unlikely to do so. When an app fails, it does so without crashing the operating system.

When Windows meets a “STOP Error“, a blue screen appears. Windows will crash and cease running as a result of this serious failure in your system.

At that moment, you are left with nothing but to restart the computer. Because programs don’t get a chance to store their open data, this might result in data loss.

When you see a blue screen, Windows produces a “minidump” file. This specific file includes crash information and stores it on your system’s hard drive. You may look up information on these minidumps to see if you can figure out the cause.

The appearance of blue screens varies based on the version of Windows you’re using. The blue screen in MS Windows 7 & preceding versions resembled a terminal screen, presenting a variety of data.

In general, blue screens are significantly easier to fix with Windows 8 and 10. In fact, it is not as big of an issue as it may seem. Even in prior versions, the blue displays moved so quickly that reading the content was impossible.

There’re other simpler methods to get all of the information you want for troubleshooting.

What Exactly is tcpyp.sys?

Let’s get to the main point now; what is tcpyp.sys? Tcpyp.sys is an abbreviation.

That represents Transmission Controls Protocol over Internet Protocol (TCP/IP). 

This file is required for a number of Windows operations. As a result, if this file is destroyed or corrupted (typically due to corrupted drivers or malfunctioning hardware). Then, it might lead to serious system issues. One of these is the tcpyp.sys BSOD.

What Error Codes Are Associated with the tcpyp.sys BSOD?

When you notice tcpyp.sys BSOD error, the following error descriptions appear.

It is true that BSoD error can lead to many consequences, including data loss. So, we highly recommend you create timely backups on your computer. If you have the latest backup, you can retrieve those files in the event of a data loss.

With that said, below are the methods you can use to fix tcpyp.sys error.

Solutions to Fix tcpyp.sys Blue Screen of Death Error

Mentioned below are the solutions you can try if you notice tcpyp.sys BSOD on your screen. So, if you are bothered by that error, you can go ahead and try these solutions.

Solution 1: Reset Your System’s TCP/IP

TCP/IP is related to tcpyp.sys, as stated in the preceding paragraph. Resetting TCP/IP is the first solution you may attempt.

What is the best way to do this? Please see the tutorial below for further information.

  • First, you should go to the search bar and enter the text “Command Prompt“. When options appear, just perform a right-click on the most appropriate result. Then, please click on the option called “Run as Admin…“.

  • Click on the option called “Yes” when it is prompted.
  • Enter the below code in the command prompt that is already opened.

netsh int ip reset

  • After that, you can restart the device. After that, check if the tcpyp.sys error is gone.

Solution 2: Update the Drivers of Your Network Card

Corrupted disks are the second probable cause of tcpyp.sys BSOD. So, to repair this blue screen issue, try upgrading network card drives.

  • You should launch the utility called “Device Manager“. To do that, you should press both Windows and R keys together. After that, you should enter the text “devmgmt.msc” and hit enter. That will bring the “Device Manager” utility up.
  • Now, find the option called “Network Adapter“. You should expand the “Network Adapter“. After that, you should perform a right-click on the driver that is corrupted or failed.
  • Then, choose the option called “Update Driver“. Find the network driver and update it with the same steps.
