By Sophie Luo in Blue Screen Error Tags: BSODnvlddmkm.sysTDR

If you’re seeing VIDEO_TDR_FAILURE (nvlddmkm.sys) blue screen of death error, you’re not alone. Many Windows 10 users with NVIDIA graphics card are reporting this problem as well. But no worries, it’s possible to fix. Here are 4 fixes for you to try. 


TDR stands for Timeout, Detection, and Recovery components in Windows. It’s supposed to be there to help stop BSODs by resetting the GPU and/or driver when there is an issue of long delay. If problems happen too many times in a row, a blue screen of death occurs. 

How do I fix it? 

Dreadful as a blue screen error could be, it’s possible to fix. Here are 4 solutions for you to try. You may not need to try them all, just work your way down and find the one works for you. 

1. Clean Re-install NVIDIA Graphics Driver
2. Update Nvidia Graphics Driver
3. Check Possible Drivers or Programs Conflict Check 

4. Run chkdsk and memtest Tests

Method 1. Clean Re-install NVIDIA Graphics Driver

Corrupted graphics card driver could be the cause of a Video_TDR_Failure blue screen problem. You can try reinstalling your NVIDIA graphics driver to fix it: 

Note: Before we go in, you need to go to Safe Mode

1) On your keyboard, press the Windows logo key and X at the same time. Click Device Manager

2) Expand Display adaptersRight-click your NVIDIA graphics driver and click Uninstall

3) When prompted to confirm the uninstall, check Delete the driver software for this device and click OK

4) Download and install the latest version of NVIDIA graphics driver from the official support website. Or you can use Driver Easy to scan and download the correct driver automatically for you. 


 5) Follow the path C:\Windows\System32\Drivers and locate nvlddmkm.sys. Right-click to Rename it nvlddmkm.sys.old

If you see this notification, click OK to continue. 

6) Go to NVIDIA directory (usually in C:\Nvidia or C:\drvvganVidia) and find nvlddmkm.sy_. Or you can just type the name into the search box. Copy this file and Paste it to your Desktop directory. 

7) On your keyboard, press the Windows logo key and X at the same time, click Command Prompt (Admin)

8) In Command Prompt window, type in the command below and press Enter

expand.exe nvlddmkm.sy_ nvlddmkm.sys

 9) Go to C:\ drive again and copy the newly created file nvlddmkm.sys

Paste into the C:\Windows\System32\Drivers folder. 

10) Restart your computer. 

Method 2. Update NVIDIA Graphics Driver

This problem is very likely to be related to outdated or faulty display driver. If the above method fail to resolve it for you, you need to update your NVIDIA display card driver. 

If you don’t have the time, patience or computer skills to update your drivers manually, you can do it automatically with Driver Easy

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to risk downloading and installing the wrong driver, and you don’t need to worry about making a mistake when installing. 

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 clicks (and you get full support and a 30-day money back guarantee):

1) Download and install Driver Easy. 

2) Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers. 

3) Click the Update button next to the flagged NVIDIA device to automatically download and install the correct version of it (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All). 

Method 3. Check Possible Drivers or Programs Conflict

1) If you’ve recently installed new drivers or programs on your PC, remove them or upgrade them to the latest versions. 

2) It’s reported that driver conflict with Logitech webcam and integrated webcam would cause this problem. So you might want to remove your external webcam and uninstall its drivers to see if this problem is gone. 

Method 4. Run chkdsk and memtest Tests

Blue screen of death errors are usually related to corrupted or faulty hard drive or RAM. You can run some tests to check if your disk or RAM is at fault: 

  • Run Disk Check

This check is to help you verify that whether the problem is caused by your hard drive. 

1) On your keyboard, press the Windows key and X at the same time, click Command Prompt (Admin)

When prompted with the administrator permission, click Yes

2) In the command prompt window, type in the following command and press Enter.  

chkdsk /f c:

Note: If the setup file of your Windows is not stored in disk C, you need to replace the c: with the appropriate disk letter.

Type Y and restart your computer for the disk check to start. 

You’ll see the checking process happening when you restart your computer. Wait for it to finish. 

  • Run Memory Test

This test help you verify that the RAM is not producing errors. 

1) On your keyboard, press the Windows key 
and R at the same time to invoke a Run command. Type mdsched.exe in and press Enter.

2) You could click Restart now and check for problems (recommended) to check the status of your memory card right now, or click Check for problems the next time I start my computer if you are too occupied now.

3) You’ll be seeing this page showing the progress of the check and number of passes it will run on memory.

If you don’t see any error here, it’s likely that your memory card is not causing any issues.

    Do not go to Drivereasy to update drivers. Always go to the manufacturers website to get them. These other sites have malware.

  • Kaman Wu

    I only have this problem when I start my windows 10 (from power off to power on).
    I do NOT have this problem when I restart (reboot) my windows 10.

  • Phani Allada

    when i try to update drivers through Geforce software the problem occurs. The system is fine without updating the drivers. Problem occurs only when i try to update them. What could be the reason.? should i stay with stock drivers installed through CD that is given with graphic card..!

    • Sophie.Luo

      Hi, Matthew.
      Code 39 error can usually be fixed by re-installing your graphics card driver.

    A damage hard drive could also be the cause. I have a HDD that will not install windows nor any software programs however i can use it as a storage device now. I hknow my HDD is damaged after I umm…. Had a fork and knife and plate smack it and then fork continued to make its way into the motherboard. Freak accident.

  • Ashan

    Can`t install drivers when in safe mode. Nvidia is not recognizing the display hardware.

    • Pichu Pokémon

      Be sure let windows install the default/generic drivers for your current VGA. Then you should able to install the Nvidia Drivers correctly.

  • My96 Moments

    I don’t know where to paste ‘nvlddmkm.sy_’ to. Can I get some help?

  • André Moutinho

    I’ve done step 1 entirely and the problem didn’t got solved . When i finished step 1 , after restarting my pc , the drivers seemed to have dissapeared , it was like I didn’t even had my drivers installed ..
    Could I have done something wrong ?

    I know for a fact that the problem is associated to the drivers because the rest is good , i’ve done all the tests.

  • Petey

    Heya, cheers heaps for these instructions. I am not technical with computers so I have gotten as far as step three and uninstalling the graphics card in safe mode.

    Just checking that wth are 4, where I install new driver, that I take the computer out of safe mode?

    Thanks again

    • Sophie Luo

      Hi, Petey.

      It is suggested that you use Driver Easy to help you with the download and install of the NVIDIA driver. It is a free program, and it won’t charge you anything. Follow the on-screen instructions, and you will be able to download the correct driver for your system.

      You can download it from this address here:

  • Renan

    I tried all the steps but I keep getting the bsod randomly when I turn the computer on or when I return from sleep mode. I am using a Razer Blade 14 late 2016, the one with the gtx 1060.

    • Sophie Luo

      Hi, Renan.

      So sorry to hear that you ran into this problem.

      It is suggested that you download Display Driver Uninstaller and then use it to uninstall your current display driver first.

      Then use Driver Easy to scan your system for needed display driver.

      The best matched driver for your display card can be found with Driver Easy.

      Then install it as instructed.

      This problem is mainly a driver issue or damaged GPU. Hope this method works for you.

      If not, please feel free to reply and we will see what more we can do.

  • richard

    thank you work great, only I just download a copy of the .dll and out in in the folders because it wasn’t even on my system and the ones that were weren’t working as should be 2 days no crashes thank for the guide.

    • Say

      Could you describe in details what you did exactly and how it helped?

  • Ellis Shuman

    As someone who doesn’t fully understand these technical directions – why couldn’t you just right click on the driver and select “update” instead of “uninstall / delete driver”?

    Also, would your program Driver Easy do the process automatically?

    In my system32 files I can’t find the nvlddmkm.sys driver file, but in my mini dump file which I examined it said that driver was the cause.

  • Garrick the Quiet

    I’ve tried upgrading my graphic card geforce gt 220 from this site: “”;

    I installed it after I’ve deleted “Nvidia graphics driver” on “Device Manager>Display Adapters” ;

    during installation , it freezes into half black and colored screen and the blue screen of death reappeared!;

    so I redo the “Safe Mode #4” option, and was intervened with blue screen again of death again before reaching Windows 10 in safe mode;

    however, I think I have two options:

    1. there’s another “MHQL” update available for geforce, and I dowloaded it too. .. but it says 32bit, the Win 10 I’m using is 64-bit.

    2. reinstall all and nuke the shit out of Blue Screen epidemic.

    any help?

    • Sophie Luo

      Hi, have you tried to use Driver Easy to help you scan for the needed driver?

      If not, it is suggested that you do the scan and then download the correct driver for your system.

  • HOU

    I think the instructions up there missed something
    if you all dont bother to try again. 🙂

    1. follow the instructions until step 6. after you copy the file nvlddmkm.sy_, paste it in C:\ drive

    2. then in the command prompt (admin), type CD C:\
    then type expand.exe nvlddmkm.sy_ nvlddmkm.sys

    After that, follow the rest of the instructions above

    hope it will work for you

    • My96 Moments

      When I typed in C:drive I’m search it doesn’t come up. So I can’t paste it since I can’t find it. Any suggestions?

      • ChrismoPrismo

        It’s called C: And it Is a drive not named “C:drive” just open command prompt and type without ” “cd ..” untill you reach “C:”

    • Michael Madison

      Thank you!! That really helped lol

  • kermit

    Awesome guide thank you

  • Moad Sadka

    it says “can’t input file: nvlddmkm.sy_.”
    any suggestions ?

    • Sophie Luo

      Hi, Moad.

      Please open the Command Prompt in Administrator mode, and then type in the commend to try again.

    • matt L

      That’s because in the above steps you need to move the nvlddmkm.sy_ to the C:\ drive in the root drive itself not on the desktop otherwise the command would be C:\User\%USERNAMEGOESHERE%\Desktop then type the command.
      This happens even when you run it in a elevated command prompt.
      Hope this helps!

  • Eric

    At the cmd step I’m getting: “Can’t open input file: nvlddmkm.sy_.”

    • Sophie Luo

      Hi, Eric.

      You need to run the commend in Administrator mode for it to take effect.

      Please try again.

  • Roberto GAstobiza

    The command line says it cannot open the nvlddmkm.sy_ file….
    No progress

    • Sophie Luo

      Hi, please run the commend in administrator mode, and then type in the commend.

  • James

    Wow. I had the NVLDDMKM.SYS blue screen on my ZT Systems i7 desktop. I went to Nvidia Drivers and downloaded the updated driver set and installed. Problem fixed. My graphics card was a DT series card.

  • GDD

    • Sophie Luo

      Il faut que l’invité de commandes soit en mode administrateur

      Pour que l’invité de commande soit en mode “admin” il ne suffit pas d’étre administrateur sur le pc. Pour en être sûr :

      Démarrer > Tous les Programmes > Accessoires > Click droit sur “invité de commandes” > exécuter en tant qu’administrateur

      Ensuite réssayer la manipulation.
