[Fixed] Ndis.sys Failed Blue Screen Error

What is NDIS and Ndis.sys error?

NDIS stands for Network Driver Interface Specification. It is a programming interface for network drivers in the Microsoft Windows operating system. Essentially, NDIS allows different network interface cards (NICs) and network protocols to communicate with each other.

"Ndis.sys" is a system file in Windows that is associated with NDIS. It is a driver file responsible for managing network connections. An "NDIS" or "Ndis.sys" error typically indicates a problem with the NDIS system file or a related network driver.

What causes Ndis.sys failed error on Windows computer?

Typically, the file will not do any damage to your computer or impair its performance. However, a variety of causes can cause difficulties with the ndis.sys file, such as Ndis.sys failed BSOD with the error message driver_irql_not_less_or_equal, excessive latency, and so on.

There are other possible explanations. Some people have tried deactivating Ndis.sys to resolve this issue, however this is not advised. After all, it is required for Windows to work properly, and disabling it will cause it to restart automatically.

If upgrading or rolling back the network drivers does not address the problem, consider replacing the Network Interface Card (NIC) using the following steps:

Step 1. Find out the make and model of your current NIC. This information is usually available in Device Manager or on the NIC itself.

Step 2. Check the NIC's compatibility with the system specifications.

Step 3. Unplug the power supply after turning off the computer.

Step 4. Find the NIC by opening your computer casing, then remove it.
