The dreaded Blue Screen of Death (BSoD) is a sight no computer user wants to see. It signifies a critical error that has caused the operating system to crash, leaving users frustrated and potentially losing unsaved work. One particular BSoD error that users may encounter is the Ndu.sys BSoD. In this article, we will explore what Ndu.sys is, why it causes BSoD errors, and how to fix it.
Understanding Ndu.sys
Ndu.sys is a system file associated with the Windows Network Data Usage Monitoring Driver. It plays a crucial role in monitoring and managing network data usage on Windows systems. This driver is responsible for collecting data related to network usage, such as the amount of data transferred and the applications consuming network resources.
While Ndu.sys is an essential component of the Windows operating system, it can sometimes cause issues that lead to BSoD errors. These errors typically occur due to conflicts with other drivers, hardware issues, or corrupt system files.
Common Causes of Ndu.sys BSoD Errors
Several factors can contribute to Ndu.sys BSoD errors. Understanding these causes can help in diagnosing and resolving the issue effectively. Here are some common causes:
- Outdated or incompatible drivers: Incompatible or outdated drivers can conflict with Ndu.sys, leading to BSoD errors. It is crucial to keep all drivers up to date to avoid such conflicts.
- Hardware issues: Faulty hardware components, such as a malfunctioning network adapter, can trigger Ndu.sys BSoD errors. Checking the hardware for any issues and replacing faulty components can help resolve the problem.
- Corrupt system files: Corrupted system files can disrupt the functioning of Ndu.sys and cause BSoD errors. Running a system file checker scan can help identify and repair any corrupt files.
- Malware infections: Malware can infect system files, including Ndu.sys, and cause BSoD errors. Regularly scanning for viruses and malware using reliable security software like Malwarebytes Free is essential to prevent such infections.
How to Fix Ndu.sys BSoD Errors
Resolving Ndu.sys BSoD errors requires a systematic approach. Here are some effective methods to fix this issue:
1. Run the DISM and SFC scans
DISM (Deployment Image Servicing and Management) and SFC (System File Checker) are built-in Windows tools that can repair corrupted or missing system files and restore the health of your computer. Both DISM and SFC scans can be run from an elevated command prompt (with administrative privileges). Here are the steps to do so:
- To open the Command Prompt as an administrator in Windows, type “cmd” in the search bar and then right-click on the Command Prompt result and select “Run as administrator” as shown in the image below.
- To run a DISM scan, type the following command and press Enter:
dism /online /cleanup-image /restorehealth
This will check your Windows component store for corruption and automatically fix any problems it finds. This process may take several minutes or longer depending on your system
- To run an SFC scan, type in the Command Prompt the following command and press Enter:
sfc /scannow
This will scan all protected system files and replace any corrupted or missing ones with a cached copy. Wait for the scan to complete. It may take some time depending on your system configuration.
- After both scans are completed, you should restart your computer to apply any changes. Check to see if the issue is solved.
2. Check for faulty software.
If there is a specific program that is causing this issue, try uninstalling and then reinstalling it (eg. Microsoft DirectX, Microsoft Visual C++ Redistributable, NET Framework) to check if it will solve the problem.

7. Clean Install Windows 10
At this point, if none of the solutions above have been successful in resolving this BSOD error, it is most likely due to some system malfunction that cannot be resolved conventionally. In this case, you can back up your files to an external USB drive. If you can’t boot to the desktop, use a Linux Live USB to back up your files, or read my article on how to quickly and easily back up data on a Windows PC that won’t boot, then do a clean install of Windows 10.
Hopefully, one of the methods above can help you fix the Ndu.sys blue screen error on your Windows 10. That’s it for this tutorial. Don’t forget to leave your comments below to share your experience in following this tutorial. Thank you.
