Issue: How to fix Nvlddmkm.sys BSOD error on Windows?
Hello. I have been getting a Blue Screen at random times – Nvlddmkm.sys. In most cases, it reboots my PC during a time when I'm playing games, although it has also happened while I was idling and not doing very much. My computer runs Windows 10 if that helps.
Solved Answer
Nvlddmkm.sys Blue Screen of Death[1] is a stop error that reboots the machine as soon as it is encountered. This particular BSOD has been around for years, so it can be present on all Windows versions, including Windows XP / 7 / 8 / 10. Without a doubt, an abrupt system reboot can cause a variety of inconveniences, including work interruption and data loss.
Nvlddmkm.sys BSOD can be related to several different error codes that users reported they have been experiencing, including:
- VIDEO_TDR_FAILURE
- PAGE_FAULT_IN_NONPAGED_AREA
- SYSTEM_THREAD_EXCEPTION_NOT_HANDLED
- UNEXPECTED_KERNEL_MODE_TRAP, etc.
However, the most common Blue Screen error users come across is VIDEO_TDR_FAILURE. Nvlddmkm.sys is a critical system file, which is installed on Windows operating system by default.
The problems related to .sys files, in general, should be treated as very serious because these files are responsible for hardware and software communication and other critical functions. Consequently, if any of the .sys files get corrupted, you may not be able to open particular software or perform tasks with external hardware, such as mouse, keyboard, printer, etc.
Usually, Nvlddmkm.sys error emerges during PC startup, a software startup, when trying to connect USB, print some documents, and so on. According to experts, this error can be triggered by incorrectly configured or corrupted device drivers, bad registry[2] entries, malware, failing RAM,[3] hardware and software conflicts, corrupted system files, etc.
Therefore, in order to fix Nvlddmkm.sys BSOD, you might have to do quite a bit of troubleshooting, so it may quite a lot of time. However, we strongly recommend looking into this issue as negligence might lead to even more problems in the future. Below you will find solutions that should help you get rid of this common Blue Screen error.
Fix 1. Run an automatic repair tool
Blue Screen errors can be particularly annoying as they interrupt all the work and force a PC to restart automatically. As already mentioned, this might result in a full data loss. Despite this, BSODs perform a very important function on Windows operating systems – they prevent major damage to the OS or hardware.
That does not mean that such errors should be ignored, as it could lead to further damage to the point when the entire Windows OS has to be reinstalled. Finding the root cause of Nvlddmkm.sys or other stop errors might be quite difficult, especially for those who are not proficient with computers.
Fortunately, you don't have to worry about this, as you can instead employ automatic repair software FortectMac Washing Machine X9. Its ability to replace damaged Windows files and components can repair your system within just minutes, all without losing important files or other data.
Fix 2. Reinstall Nvidia or other graphics drivers
VIDEO_TDR_FAILURE (Nvlddmkm.sys) indicates a problem with Nvidia or GPU driver problems. Therefore, we recommend you uninstall and then reinstall drivers as explained below:

- Expand Display adapters section
- Right-click on your GPU and select Uninstall device
- In the warning prompt, tick the Delete the driver software for this device box
- Click Uninstall and reboot your PC.

For that, you need to know the make and the model of your graphics card.
If you are not sure or don't want to install the wrong drivers, there is a third option – download and install DriverFix. An automatic driver updater will download and install drivers for all system components without you having to worry about any issues that can arise due to incompatible or corrupt drivers.
