1. What Is nvlddmkm.sys?

The file “nvlddmkm.sys” is not malware — it’s a legitimate system file installed as part of your NVIDIA graphics driver package. It resides in the C:\Windows\System32\drivers\ directory and acts as the kernel-mode driver for NVIDIA GPUs. In simpler terms, it’s the bridge between your Windows OS and your graphics card, handling everything from rendering 3D graphics to managing display outputs and power states.

When Windows encounters a critical error related to this driver — whether due to corruption, incompatibility, hardware failure, or software conflict — it triggers a Blue Screen of Death to prevent further damage. The system halts, dumps memory, and reboots (if configured to do so).

Understanding that this file is essential helps frame the problem: the issue isn’t the file itself, but rather what’s causing it to malfunction.

2. Common Causes of nvlddmkm.sys BSOD

Before diving into fixes, it’s important to understand what typically triggers this error. Here are the most common culprits:
