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.
