Network Driver Interface Specification (NDIS) handles all the communication and connections between all the components and connected devices over the computer’s network. The ndis.sys file is the system file that is responsible for carrying out these operations. However, users have been getting the DRIVER_IRQL_NOT_LESS_OR_EQUAL ndis.sys Failed issue.
This file can be found in the System32 folder. Although, this file has no effect on your PC’s performance and neither does it interfere with the normal functionality of a computer. But multiple users have come across BSODs due to ndis.sys failures. It might get triggered before you even get into your windows, or it can also occur while you are booted up and try to run an app/software.
There are several different possible causes for the ndis.sys Failed issue. But worry not, we will be showing you multiple fixes to resolve it.
Note: Microsoft has ended support for Windows 7, if you are still using Windows 7 then we would strongly recommend upgrading it to Windows 10 before going through any of the fixes below. As it will not only improve your overall experience but will also improve the overall security of your data.
If you are not able to access Window at all, you will need to enter the safe mode first. You can do that by clicking “Advanced Options” when “Startup Repair” appears and then select “Advanced Options” after clicking on “Troubleshoot”. Here, you will need to select “Startup Settings” and then press “F4” on your keyboard to access Safe Mode.

Solution 6: Perform A Full Scan On Your PC
Malware/Viruses might impersonate the ndis.sys file which can cause the BSOD to appear and can also affect your PC’s performance. Performing a full scan will remove these malware/viruses from your PC. Follow the steps below to run a full scan using Windows Defender:
- Press the “Window + S” keys simultaneously and type in “Windows Security” in the search bar. Then press “Enter” on your keyboard.
- In the pop-up window click to select “Virus & threat protection” and then select “Scan options”.

Solution 7: Disable Your Antivirus/Antimalware Software
Having Antivirus/Antimalware software is important as it keeps your data safe. However, it can sometimes interfere with the system’s functionality thus causing issues such as BSOD. For this “Disable” your antivirus software and see if that fixes the issue. If it does, then you should consider switching over to different software. We would suggest using no other than Window’s own Defender software as it has improved drastically over the recent updates. Moreover, you can also replace your ndis.sys file with another one downloaded from any other website. However, we would strongly advise against it, as it can mess up your whole Windows and you will need a reinstallation of windows afterwards.
Solution 8: Perform A System Restore
If none of the solutions listed above worked for you, then you should restore your system to a restore point that was created at an earlier time. Here is how to do it:
- Press the “Window + S” keys together, type in “Control Panel” in the search bar, and press “Enter” on your keyboard.
- Click on “System and Security” from the displayed menu and select “File History”.
- Click on “Recovery” from the “See also” section at the bottom-left and select “Open System Restore”.
- Move to the “Next” step, select a restore point and follow the on-screen instructions.
- In the end “Restart” your PC and check if the problem got eradicated now.
