Many Windows users are having an issue with their computer. They are experiencing a blue screen of death error with the error code of ndis.sys occurring randomly on their Windows system.

This is very frustrating. You can’t use your Windows computer because of this blue screen error. But don’t worry. It can be fixed…

Try these fixes!

The following are a few methods that have helped many Windows users fix their ndis.sys error. You don’t have to try them all; just work your way down the list until you find the one that works for you.

  1. Check your computer for viruses or malware
  2. Temporarily disable your security software
  3. Update your device drivers
  4. Run System File Checker
If you CAN’T log in your Windows system, you’ll only need to try method 3 and 4.

Method 1: Check your computer for viruses or malware

You may get this error because there are viruses or malware on your computer. To get rid of them, you should run your security software and scan your computer. After that, restart your computer and see if your computer runs normally.

Method 2: Temporarily disable your security software

It is also possible that your ndis.sys blue screen error results from your security software itself. This error sometimes occurs because of software conflicts caused by an antivirus or firewall. To see if that’s the problem for you, temporarily disable your security program and check if the problem persists. (Consult the documentation of your security software for instructions on disabling it.)

If this resolves your problem, contact the vendor of your security software and ask them for advice, or install a different security solution.

IMPORTANT: Be extra careful about what sites you visit, what emails you open and what files you download when your antivirus or firewall is disabled.

Method 3: Update your device drivers

You may get this ndis.sys blue screen error if you’re using a wrong device driver or it’s out of date. You should make sure your drivers are updated. If you don’t have the time, patience or skills to update your drivers manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing.
