NDIS or Network Driver Interface Specification is a programming interface for the network interface cards that aids in proper functioning of a system driver in a computer network. The NDIS helps the computer system in order to communicate with other connected devices and hardware components on a computer network. In relation, the ndis.sys file is a critical system file developed by Microsoft for the Windows operating system. As you know, sys files or system files are important parts of the Windows operating system as well as a repository of system driver settings used by Windows to communicate with the connected hardware and devices.
The ndis.sys files are stored mostly in a driver folder at C:\Windows\System32\drivers and as mentioned, these files are essential for the system to function properly. Although the presence of ndis.sys system file is not yet known to affect the normal functioning of the Windows OS, some of the Windows 10 users reported that they encountered ndis.sys blue screen errors on their PCs. Blue Screen of Death errors or Stop errors usually occurs when you open a program or a function. Moreover, it could also occur when the driver gets loaded during the system startup or during system shutdown.
It isn’t yet clear what really causes the ndis.sys blue screen error. However, like other Stop errors, it may occur due to corrupted files, misconfigured device drivers, bad drivers, corrupted Windows Registry, missing or damaged system files and malicious programs. Aside from the aforementioned reasons, the ndis.sys blue screen error might also occur if your hard disk is damaged and if the RAM is corrupted. In such cases, a lot of users usually disable the ndis.sys file. However, it won’t really resolve the issue since the file is required for the normal functioning of the operating system and even when you disable the file, it’s pretty useless as the file will start all over again. In addition, you might want to disable security programs or firewalls and antivirus programs for the meantime to check if these programs are the ones that are causing the error. And if you’ve determined that none of the security programs or firewalls and antivirus programs are to blame, refer to the options below that might help you resolve the DRIVER_IRQL_NOT_LESS_OR_EQUAL or ndis.sys Blue Screen of Death error.
Option 1 – Try to update or reinstall the PC device driver
The Ndis.sys Blue screen error can occur when the device driver in your computer is outdated or corrupted. Thus, you either have to update or reinstall it to fix the issue.
- 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.
Option 2 – Rollback your Network drivers
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 one 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 3 – Try running the System File Checker
The SFC or System File Checker scan could detect and automatically repair damaged system files that could be causing the ndis.sys Blue Screen of Death error. SFC is a built-in command utility which 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 and hit Enter.
The command will start a system scan which will take a few while 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.
Option 4 – Try running the CHKDSK utility
Running the CHKDSK utility might also help you resolve the Netwtw04.sys failed BSOD error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.
- Open Command Prompt with admin privileges.
- After opening Command Prompt, execute the following command and hit Enter:
chkdsk /f /r
- Wait for the process to be completed and then restart your computer.
Option 5 – Run the DISM Tool
The DISM tool is another command-line tool in the Windows operating system that could help users fix various corrupted system files. To use it, follow these steps:
- Open the Command Prompt as admin.
- Then type in this command: DISM /Online /Cleanup-Image /RestoreHealth
- The DISM command you entered will repair the corrupted system image. Do not close the window if the process takes a while as it will probably take a few minutes to finish.
- Restart your PC.
Option 6 – Perform a System Restore
Performing a System Restore on your computer can also help you fix the ndis.sys Blue Screen of Death error. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.
- 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.
- After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.
