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:

  1. Press the “Window + S” keys together, type in “Control Panel” in the search bar, and press “Enter” on your keyboard.
