On Windows 10, the Nvlddmkm.sys error occurs. This issue can have a variety of names, such as video Tdr failure. It’s a point where the NVIDIA graphics and the system meet.
This is a graphic card-related error. You may be unable to view or play a video or game due to this problem. In this article, I’ll show you how to fix this mistake, as well as the reasons for it and what it means.
What Is Nvlddmkm.sys and What Does It Do?
Let’s have a look at what TDR is before we dive into what the issue signifies.
The acronym TDR stands for Timeout, Detection, and Recovery. It is responsible for the NVIDIA graphics card. When the TDR fails, the loading of a certain video may be delayed, or a BSOD may appear.
The abbreviation BSOD stands for Blue Screen Of Death. TDR failure is the cause of the error. This problem primarily appears on PCs that have recently upgraded to Windows 10 or have had a new driver installed.
What went wrong with Nvlddmkm.sys?
There could be a number of reasons for the nvlddmkm sys error –
Disputes between drivers
Incorrect memory timing
Drivers who have been corrupted
Voltage is low.
Graphics card issues Power supply issues
The temperature is incorrect.
When the device detects a low frame rate, it assumes that the graphics card isn’t working properly. And, as previously said, TDR-Timeout, Detection, and Recovery is in charge of this card.
The computer displays a notice stating that there is a problem with the card and that they are unclear. This is an extremely subtle error, not simply a simple mistake.
This will leave you in a quandary about what to do and what not to do with the error, and you must be concerned about your future steps.
Don’t worry; by the end of this essay, you’ll have a good understanding of the problem and how to fix it. This problem can cause your screen to go black for a few seconds before displaying a message.
You could try going back and reloading once more. If the problem persists, you should try the solutions listed below.
This could happen while you’re watching a movie or video, playing a game, or even attempting to log in.
It’s also possible that the Back Screen of Death will occur. Let’s keep moving forward and looking for answers.
What Should I Do If I Get an Nvlddmkm.sys Error?
I’ve included a few options; you don’t have to try them all. You can either try them one at a time or start with the one you’re most familiar with and work your way through until the error is resolved.
You’ll undoubtedly find at least one that works best for you! You could attempt a clean installation of the Nvidia graphics driver, renaming and copying the file where the issue occurs, updating the Nvidia graphics driver.
Checking RAM modules, disabling system overclocking, upgrading to a more powerful power supply, or using the CHKDSK utility.
You could try power restarting your system before attempting these instructions. Simply restart the computer more than twice to see whether the issue still exists.
TDR is responsible for controlling the appearance of the black screen of death, as well as managing the driver and GPU. Let’s look at some more options if these tactics didn’t work for you.
Fixing the Error Alternatives Nvlddmkm.sys
Solution 1: Install the Nvidia Graphics Driver from Scratch
The problem could very well be caused by the nvidia graphics driver. It can become corrupted or infected with malware, resulting in TDR difficulties.
BSOD is also a result of this. To fix this problem, try reinstalling the graphics driver and seeing if the problem goes away.
Step 1: Download and install the display driver uninstaller on your device. It’s also known as DDU.
Step 2: Select the option that best suits your needs. Normal mode is my preference. You can also choose between the safe and networking options. After you’ve decided on a mode, go to the launch tab.
Step 3: A Windows password is required to keep the device secure. In some circumstances, pinning isn’t an option. Quit if you don’t know your Windows password.
Step 4: On the screen, there will be a Clean and Restart option; tap it.
Step 5: After you’ve uninstalled your display graphics card, the computer will start automatically.
Step 6: After that, we’ll launch a tab with useful system tools. To do so, place your hands on the keyboard and simultaneously click the Windows key and the X button. After that, a window will appear, from which you can choose the device manager option.
Step 7: Next, select action and then scan to receive updates on hardware changes.
Step 8: Finally, the computer will begin scanning for all driver updates and will alert you of any automatic updates that are available.
Solution 2: Copy and Rename the Nvlddmkm.sys File
Step 1: To begin with this approach, make sure your computer has the most recent nvidia drivers loaded.
Step 1: Go to C:/Windows/System32/drivers and double-click it.
Step 2: Look for the nvlddmkm.sys file. The option to rename the file will appear; select it and type nvlddmkm.sys. old. After that, click OK.
Step 3: Go to your computer’s nvidia directory and look for the file nvlddmkm.sys. Copy the link and paste it on your desktop when it has been copied.
Step 4: Then, on the screen, click the Windows button. To open the command programme, put cmd into the search box.
Step 5: In the command box, you’ll need to type several commands.
Hit the enter key after typing chdir desktop.
Type expand.exe.nvlddmkm.sy nvlddmkm.sys and hit the enter key once more.
Step 6: Finally, copy your file from your desktop and paste it into the C:/Windows/System32/drivers folder. Finally, restart the computer to see if the issue is still present.
Solution 3: Install the Most Recent Version of the Nividia Graphics Driver
If the two actions above—installing the Nvidia graphics driver and renaming the file nvlddmkm.sys—did not resolve the problem in your device,
Because it’s possible that the graphics driver isn’t dependable or isn’t working properly, the third option could be used.
There are two options for resolving this problem: either contact the manufacturer for a driver update, or have it done automatically.
Manually updating the driver: To manually update the driver, contact the manufacturer, who will direct you to their location. Select the correct nvidia graphics driver from the manufacturer’s website.
Keep in mind that you should select one that is compatible with Windows, and the most recent version is usually preferred.
You may even need to cancel the driver at times. So, be cautious while selecting a driver and get one that is ideal!
Updates are Made Automatically
There is a saviour for you if you don’t want to update the driver manually, don’t have enough time to visit the manufacturer, or don’t have the abilities to select the proper driver for your computer system.
You can have it automatically updated. Yes, you read that correctly. There’s an app called Driver Easy that you may download.
It will automatically determine the appropriate drive update for your Windows and even your nvidia card.
The programme will automatically download and install the drive without any errors or hassles. All you have to do now is download the app.
What Is The Best Way To Update?
Step 1: Download and install the driver app for the device, which is readily available.
Step 2: After that, open the app and press the scan button. When you press the button, the app will scan all of the drivers and identify the one that isn’t working.
Step 3: After the nvidia device has been flagged, look for the update button, which will be right there.
When you click the update button, the latest version of the driver will be downloaded automatically; all you have to do now is click the install button to install it.
This procedure can also be completed using the free version. You do not need to buy any version in order to update and install the correct driver.
The only advantage of purchasing the version is that it will automatically download and install the correct version of each driver, as well as those that are not currently installed on your device and those that are outdated.
The pro version comes with full support and a 30-day money-back guarantee. It will reimburse your money if the driver is not working in any way.
As a result, you can select the suitable version based on your preferences. It’s also possible that the drivers or applications will clash, causing a difficulty.
If you download a new version, you must delete the old one first, or else a dispute will arise, resulting in a computer crisis.
To avoid conflicts, you can also update the old ones. Due to its integrated options, a software called camera installed on computers may cause such issues.
These softwares download drivers into your system, and if an error arises, you must uninstall these softwares, such as the Logitech webcam, as well as the drivers they downloaded.
You can check to see if the nvlldmkm.sys error is still present. Corrupted RAM or hard drives can cause BSOD issues, commonly known as black screen of death errors.
As a result, we may investigate whether they are the root reasons of the system’s error. To do so, we’ll need to run a disc check to see if the RAM or hard drivers are corrupted.
Step 1: To launch a command application, go to the device’s windows icon and type cmd. You may also run it by using the shortcut key. Run it as an administrator. It will ask for administrator permission, which you should grant by clicking yes.
Step 2: Type “cmd” in the command prompt.
Once you’ve typed it, hit enter, and when prompted, write Y.
Step 3: The machine will restart automatically and begin a disc check. Wait until it’s finished.
Another option is to take a memory test. This will tell you if the problem is caused by a lack of RAM. To do so, go to the run command prompt and type
After that, type mdsched.exe and click enter. You can check for RAM problems and the state of the memory card at the same time.
Memory testing can also be done with a specific tool called memtest 86. It’s simple to install and use to check the status.
Solution 4: Check Memory Modules
The memory strip of the computer might sometimes be the source of the nvlddmkm.sys issue, causing the computer to malfunction.
It is always preferable to utilise only one memory strip at a time, as using many memory strips at the same time can result in an error.
So, pick a memory strip. Check to see if the error persists; if it does not, there was a problem with the memory strip you just unplugged.
Solution 5: Make Use of a More Powerful Power Source
Electricity powers electronic equipment. Right? They also require a significant amount of power to function effectively. The error nvlddmkm.sys may appear if your computer is unable to obtain adequate power from the source.
It’s a good way to connect a device to a higher powerful power supply. This will undoubtedly resolve the problem, and the error will vanish.
Solution 6: Use the CHKDSK Utility
If none of the above solutions worked, you might try using CHKDSK’s functionality. This is why –
Step 1: Go to the Windows icon and type cmd to open the command prompt. Then press the enter key. Another approach is to press and hold the window and X keys at the same time.
Step 2: In the command prompt, there will be a bar where you can type. Fill in the blanks in that bar.
Enter chkdsk/f c at the command prompt.
Step 3: The computer will begin verifying the hard drive for problems. Wait for the verification to be finished.
Solution 7: Disable Overclocking of the System
This is the final but most effective solution. The computer has an artificial overclocking system, which could cause the system to overheat. The nvlddmkm.sys problem could be caused by this overheating.
Switching off the overclocking system in BIOS will simply halt this issue. If your device doesn’t have a BIOS, you can disable fake overclocking with a variety of software and apps.
Check if the nvlddmkm.sys problem still occurs when you try to access the media.
I’m hoping that one of these options worked for you. These are easy-to-implement but very effective solutions. You’re probably not getting the nvlddmkm.sys error right now.
If the nvlddmkm.sys error persists, it is always a good idea to contact customer service for any more assistance.
