When gaming or performing any simple task, your computer might give you a black screen and revert to a normal screen. This either means that you have a loose power supply or your graphics driver is not responding correctly.
If it’s the latter, you may get a message on the error log that says, “Display driver nvlddmkm stopped responding and has successfully recovered.” Nvidia Windows Longhorn Display Driver Model Kernel Mode or the NVLDDMKM is a driver that helps with the communication between the OS and the Nvidia graphics driver.
So, if this driver fails,the computer will lose its display. If this error persists, you may also get a constant Blue Screen of Death, decreasing the health of your computer drastically.
What Causes NVLDDMKM Error?
The Nvlddmkm is a driver for the Nvidia graphics card. A corrupted driver can cause theNvidia driver to malfunction.However, this is not always the case, as memory conflicts may also cause this error. Keeping this in mind, here are a few reasons the NVLDDMKM driver fails.
How to Fix NVLDDMKM Error (Display Driver Stopped Responding)?
Now that we know what causes the display driver to stop responding, let us get to the solutions to fix the NVLDDMKM Driver error.
Run the SFC and DISM command
The SFC or theSystem File Checkercommand will check the system file for any corrupted file and attempt to fix these files. These system files are located insideC:\Windows|System32. As all driver files are installed inside System32, we can use this and the DISM command to scan and repair any corrupted driver files.
Please follow these steps to run the SFC command.
Once the SFC process is complete, we need to run the DISM command. The DISM or Deployment Image Servicing and Management command checks, scans, and repairs the local Windows Image.
Now, type these commands and press Enter after each command.
Once all processes are complete, you can restart your computer.
Change Link State Power Management settings
The Link State Power Management can sometimes cause the nvlddmkm error when turned on. Basically, the Link State Power Management is a part of the PCIe specification that manages the power supply to the PCIe port.
So, when this feature is turned on, the PCIe will get relatively lower power. This, in turn, causes the graphic card to malfunction sometimes. Therefore, we need to turn off this power-saving feature.
Once you have completed this process, please restart your computer.
Disable High Precision Event Timer
The HPET driver, or High Precision Event Timer helps generate periodic interrupts that OS uses to synchronize multimedia streams, resulting in smooth gameplay. However, in some rare cases, this driver can also make the display driver irresponsive to OS requests.
To disable this driver, you can follow the steps mentioned below.
Change the Power Supply
If a computer’s power supply starts to fail, it will deliver low power to all connected components. This results in insufficient power for the GPU (Graphics Processing Unit) as well.
So, when we perform graphics-intensive tasks on these computers, the GPU may stop communicating with the processor, which simultaneously leads to a driver failure error or, in this case, NVLDDMKM error.
We can check if the power supply provides enough voltage from the BIOS (Basic Input and Output System). In the BIOS, we can check the PC’s health, and it will display how much voltage some component requires. If the voltage status is irregular, it is best to change the power supply.
Revert Fan Control Settings
Fan control software manages the temperature of your CPU and GPU. So, if settings inside these applications are improper, it may cause yourgraphics card to overheat. When a graphics card overheats, its performance will decrease. Try reverting these settings to default to see if it fixes the issue.
Change MSI Afterburner Settings
If you have a gaming PC, you are probably familiar with the MSI Afterburner. It is one of the best applications to monitor your hardware in real-time. However, the default setting lets Afterburner enable the GPU sensors to better hardware status. This may cause the Nvidia display driver (nvlddmkm) to crash.
Disable these two settings in MSI Afterburner to fix the Nvidia driver issue.
Follow these steps to disable the settings that are mentioned above.
These settings are not only limited to MSI Afterburner, applications like GeForce Experience,Razer product applicationor Aura iQUE will also have these settings enabled. Therefore, it is ideal to disable these settings.
Change Graphic Card Slot
As we get the error NVLDDMKM from an unresponsive GPU, it is normal to assume that the PCIe port is faulty. The PCIe port connects your graphics card to your motherboard. A damaged PCIe port may be the reason behind your graphic drive not responding.
You can swap your graphic card to a different PCIe slot on your motherboard to see if it fixes the issue. However, we need to be careful while removing and inserting the graphic card onto the PCIe slot.
While changing the graphic card slot, we recommend cleaning the graphic card. Similarly, a graphic card can get overheated if thefans do not spin properly. This will result in a choppy GPU performance.
Underclock GPU
An overclocked GPU will boost your gaming performance but it also puts a lot of strain on your graphic card. These strains can cause your graphic card to give a choppy performance. So, try underclocking the GPU to see if it fixes the nvlddmkm error.
Here are a few ways we can underclock the GPU.
Change TdrDelay value
The TDR stands for Timeout Delay, and the Recovery tool detects any GPU failures and recovers them. The TdrDelay value determines the maximum time the GPU can stay unresponsive. If we increase this value, your OS will wait a specified period until your GPU responds.
Changing this value will not stop the driver error, but it canprevent your computer from entering Blue Screen of Death. Please follow these steps to change the TdrDelay value.
How to Add TdrDelay?
If you cannot find TdrDelay, follow these steps to add it in the Registry.
Check Memory Module
As the GPU does require some physical memory to perform its tasks, faulty memory is also a reasonable cause for you getting the driver not responding error.
In order to check the health of your primary memory,
Once the test is completed, it will give you the status of your physical memory.
We can easily check if we have a faulty memory if our system runs on dual memory sticks. Remove any one of the RAM sticks and turn on your computer. If it turns on smoothly and you do not get the nvlddmkm error, we can conclude that the other stick was faulty.
If thecomputer still crashes, remove the other RAM stick and insert the previously removed one. Once you find the faulty RAM stick, replace it with a new one to fix the issue.
Unfortunately, if you run your system with a single memory module, you will needanother RAM stick to testif the RAM you are using is performing correctly.
Update/Roll Back Nvidia Graphics Driver
An outdated driver may cause issues while sending or receiving data with the OS. Therefore,updating the driver to the latest versionis always helpful to avoid errors like NVLDDMKM errors.
Follow these steps to update your graphics driver.
Press theWindows + Xkey and selectDevice Manager. Here, expandDisplay Adapters, right-click on Nvidia driver, and clickUpdatedriver. Restart your computer once the update is complete.
If you are using a Nvidia graphics card, we can use GeForce Experience to update all our drivers including the Nvidia Graphics Driver.
If the NVLDDMKM error starts after a display driver update, we can roll back to the previous version to check if it fixes this issue. To roll back a driver update, double-click on theNvidia display driver, here you’re able to see an option toRollback driver.On choosing this option, the driver will revert to a stable version.
Reinstall Nvidia Graphics Driver
If the Nvidia graphic driver gets corrupted and updating and rolling back the driver to the previous version does not fix the issue, we can try reinstalling this driver. Firstly, we need to uninstall the earlier version of the Nvidia driver. The following steps will help you uninstall a driver.
Go toDevice Managerand expand theDisplay adapter, then right-click on yourNvidia driverand selectUninstall.
We need to download the latest driver fromthe official Nvidia website. Once you open the website, select your OS and graphic card’s type, series, and product. Click on search and then download the driver.
After the download is complete, run the file and follow the Nvidia Driver’s installation process.
Update Windows
The Windows Update feature will update all our drivers and the OS simultaneously. Updating Windows to the latest version will also solve any compatibility issues. you’re able to follow these steps to update Windows to the latest version.
Click on Start menu and go toSettings>Windows Update(Security & update>Windows Updatefor Windows 10). Here, you may download the update by clicking onCheck for updates. Once the download is complete, restart your computer to install the update.
What Causes nvlddmkm.sys Blue Screen of Death
When a display driver stops responding, the OS will wait a certain amount of time for the driver to respond. During this period your computer will have a black screen. If the driver responds back, the error log may display the error message “Display driver nvlddmkm stopped responding and has successfully recovered.”
However, if the OS does not get any response from the driver, it again waits for a certain amount of time to restart. If this driver does not respond, we get a Blue Screen of Death.
Here is a list of reasons a GPU can stop responding.
