🧨 What Causes the nvlddmkm.sys Failed Error?
The nvlddmkm.sys is a core system file used by NVIDIA graphics drivers. It serves as the Windows Display Driver Model (WDDM) kernel-mode driver, enabling your GPU to communicate with the operating system and render visuals smoothly.
When you encounter an error like:
❗ “nvlddmkm.sys failed with status 4” or
❗ “nvlddmkm.sys failed to load or was not found”
…it often results in a Blue Screen of Death (BSOD), causing your system to crash unexpectedly.
Common Triggers:
- 📦 Corrupted, outdated, or incompatible NVIDIA drivers
- 💥 Conflicts after Windows updates
- 🔌 Hardware issues such as overheating or failing GPU
- 🧬 System file corruption or registry damage
- ⚡ Overclocking or unstable GPU settings
In this guide, we’ll walk you through step-by-step troubleshooting methods to resolve the nvlddmkm.sys failed error on Windows 10 and 11, including each method’s success rate based on real-world user reports.

- Manually reinstall the latest NVIDIA driver.
🛠️ Highly recommended for stubborn driver issues.
✅ Method 4: Check for Windows Updates – Success Rate: 80%
Sometimes, missing system updates can cause driver conflicts.
Steps:
- Go to Settings > Update & Security > Windows Update.
- Click Check for updates.
- Install all pending updates and restart your PC.
✔️ Ensures compatibility between your OS and graphics drivers.
✅ Method 5: Run System File Checker (SFC) – Success Rate: 75%
System file corruption can prevent the driver from loading correctly.
Steps:
- Open Command Prompt (Admin).
- Type:
sfc /scannow- Wait for the scan and repair process to finish.
🧹 Repairs damaged or missing system files that might be interfering with GPU drivers.
✅ Method 6: Disable Overclocking or Reset GPU Settings – Success Rate: 85%
Overclocked GPUs can become unstable and trigger crashes.
Steps:
- Use tools like MSI Afterburner or EVGA Precision X1.
- Reset clock speeds and voltage settings to default.
- Monitor GPU temperature using HWMonitor or GPU-Z.
🔧 Helps eliminate instability caused by overclocking or overheating.
✅ Method 7: Test for Hardware Issues – Success Rate: 65%
Physical problems with your GPU (like faulty VRAM) can also lead to this error.
Steps:
- Run stress tests using tools like FurMark or MemTestG8.
- Watch for screen artifacts, freezes, or crashes during testing.
- If possible, test with another GPU or in a different system.
⚠️ Lower success rate, but crucial if software fixes fail.
