Video TDR Failure (atikmdag.sys) on Windows 10 [Solved]

Sophie Luo, in Blue Screen Error Tags: BSOD

If you’re using AMD or ATI graphics card, and you’re seeing a VIDEO_TDR_FAILURE blue screen error, you’re not alone. Many Windows users have reported to have seen it before. 

As annoying as a blue screen of death error can be, it’s possible to fix. Here are 3 solutions for you to try. You may not need to try them all, just work your way down until you find the one works for you. 


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’s 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? 

Note: If you’re with NVIDIA or Intel display driver, the error codes are nvlddmkm.sys and igdkmd64.sys, just slightly different. 

1: Update Display and Chipset Drivers
2: Re-install Driver in Safe Mode
3: Fix in Command Prompt

1: Update Display and Chipset Drivers 

If your PC fail to reset the display driver and recover from a timeout, a Video_TDR_Failure blue screen would occur. You can update your chipset and display card driver to fix it: 

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

2) Expand Display adapters. Right-click your video driver and click Update Driver Software…

3) Click Search automatically for driver software

4) Wait for a while for Windows Update to help you with the searching for latest driver.

5) If Windows Update prompts to tell you that the latest version of your ATI/AMD graphics card driver has been found, just follow the instructions to get it installed. 

Do the same procedures with your chipset driver to get it updated. 

There are times when Windows fails to update your chipset driver or display driver to the latest version. So you may need to download and install them by yourself. 

If you’re a computer novice and have no idea how to update your device drivers, we recommend using Driver Easy. It’s a tool that detects, downloads and (if you go Pro) installs any driver updates your computer needs.

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 your flagged AMD driver and chipset driver to automatically download and install the correct version of them (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). 

2: Re-install Driver in Safe Mode

Note that you need to have the latest version of Intel chipset driver and ATI/AMD graphics card driver in your computer. You can download them for free with Driver Easy first. 

1) Go to Safe Mode in Windows 10

2) Go to Device Manager again. Expand Display adapters. Right-click AMD/ATI device and click Uninstall

3) Click OK.

4) Reboot your computer into the normal mode. Then install the latest version of Intel chipset driver for your computer.

5) Reboot your computer again. 

6) Try installing the latest version of the ATI/AMD device driver on your computer again. 


3: Fix in Command Prompt

1) Download the latest version of ATI/AMD graphics card driver first. You can do so with Driver Easy

2) Follow the path C:\Windows\System32\drivers and locate the atikmdag.sys file. Rename it as atikmdag.sys.old

3) Go to ATI directory (Usually in C:\ATI) and find the file atikmdag.sy_

Copy the file to your desktop. 

If you can’t find it in this folder, try typing the name of the file into the search box in the Start panel. 

3) On your keyboard, press the Windows logo key. Type cmd and click Command Prompt

4) Type chdir desktop and press Enter to change the directory to your Desktop. 

5) Type expand.exe atikmdag.sy_ atikmdag.sys and press Enter

Or, type in expand -r atikmdag.sy_ atikmdag.sys and press Enter.

6) When the expansion is complete, copy the new atikmdag.sys file from your Desktop to C:\Windows\System32\Drivers

7) Restart your computer and the problem should be resolved.

  • Ayan

    I think i should use 2nd safe method but u says we need to have latest version of AMD drivers … when i checke whether latest version is available or not my laptop says ” the best driver software for your device is up to date”. Whichh mean i dont need to install another version right? So, can i move on toward another step????

    Help before my father kill me lol

    • Sophie.Luo

      Yes, you can move on and go to safe mode if Device Manager tells you that your driver is up to date. But it’s also recommended that you search for and download the latest version of AMD and chipset drivers on your PC and install them by yourself later in safe mode. Or you can use Driver Easy to scan and download them for you for free. Feel free to let us know what more we can do to help.

  • Riko

    • fdsa fdsafa

      I have the same exact video card and just got this error. Now I am scared. Did you manage to fix the error yet?

  • Sniper joe

    For method 3 I cant find the file in Windows32drivers, the only place i can find it is in file repository. I was wondering if there was a different place I could look for it?.

  • Legoals

    I can’t try these method, since my computer aren’t able to show anything after the blue screen, and after force restart it goes to the blue screen again, in a endless loop, is there a way to fix that, or do i need to buy a new graphic card?

  • Philip

    So for a few hours, I struggled with my windows 10 laptop ( AMD graphics card) that just kept on restarting and giving me the same blue screen and Video tdr failure atikmpag.sys error.
    The problem is, whenever I open my laptop to try to update the graphics software, the laptop restarts before im able to finish the process. Im stuck in an endless loop and im unable to fix it! Is there any way to stop the automatic restart just to be able to download and update the software?
    Thanks in advance!!

    • Sophie Luo

      Hi, it is suggested that you download Display Driver Uninstaller and use it for the uninstall of your display driver.

      Display Driver Uninstaller allows you to choose whether or not to restart your computer automatically or not.

      When the uninstall finishes, you should be able to reinstall your driver back on again.

  • Rushikesh

    when ever I start up my PC my second monitor stops working and AMD keeps telling me “could not load file or assemble MOM.Implementation or one of its dependencies. The system cannot find the file specified” THEN when i try to launch AMD catalyst control center to fix my second monitor “could not load file or assemble CLI.Implementation or one of its dependencies. The system cannot find the file specified” I know that there is nothing wrong with the monitor and i know AMD is the problem how do i fix it?

  • Bruce Chastain

    FYI for all you Googlers, I too had the AMD driver atikmpag.sys VIDEO_TDR_FAILURE crashes. I have a new Asus Z270-A motherboard and a XFX RX480 video card. What did work was changing the PCI Express speed setting for that slot back to 2.0 in the BIOS, rather than the default speed of 3.0.

    Personally I think it is a bug in the AMD driver or the RX480 chips.

  • deepak

    hello sir,i just bought my pc 20 days earlier. i have window10 in my pc .when i on my pc, my pc display like blue and on the display be written like that”your pc ran into a problem ,we just like to restart it “if u know more about it please go to “video tdr failure” .i have also changed my window10 of AMD too but i could not get a good result .please help me

    • Sophie Luo

      Hi, Deepak,

      In this case, it is highly recommended that you take your PC back to the manufacturer and ask for a full check out to see if there is anything wrong with the hardware.

      Your PC is rather new, and this sort of problem should not happen on a new PC.

      Hope this is helpful.

  • S.J. Park

    Hi, I tried your method 2. Because of the atikmpag.sys thing, the only way for me to log into my computer was using the safe mode though the startup settings. So I went through your process, and it seemed working as I could reboot my computer into the normal mode. So, I downloaded and installed the latest Intel Chipset Device Software. And I rebooted again as you wrote above.
    However, from that point onward, the Video Tdr Failure atkimpag.sys has come back and I can’t go back to the normal mode.
    What should I do now??

    • Sophie Luo

      Hi, S.J. Park.

      So sorry to hear about this.

      You mentioned that you are now unable to boot into your desktop, right?

      In this case, please try:

      1) Perform a hard reboot of your computer to log onto your desktop;

      2) When you are able to log in, go to Device Manager to uninstall the driver that you previously installed;

      3) Download Driver Easy from this link here:

      4) Use Driver Easy to scan for the correct display driver that you need; then download and install it as instructed.

      NOTE: The reason why you have this problem could be that you have not downloaded the correct version of the device driver. So please allow Driver Easy to tell you what version of the driver is good for your PC and then you can choose to download it by yourself or with Driver Easy.

    I have this problem with my pc running windows 10 – it just shuts down on its own – no warning. The error message is “video TDR failure”, what fails is atikmpag.sys
    I have check the driver for my graphics card and it says it is up to date !

    My graphics card is ATI Radeon HD4600 Series

    …now I check your website and if I am not mistaken this graphics card is no longer supported !!!

    If this is the case – what are my options ?

    I have wasted so much time on this and feel cheated – I never asked to install win 10 on my pc – it just installed itself one day because I was away from the pc, and was unable to decline the install which started automatically – now I have a pc that is almost useless !!

I think my problem is solve and then i reboot my notebook. But after a few minute i use my device i still have the same message.
    what must i do next? can you help me

  • John RG

    Tried your Method One driver update solution. Seems to have stopped the screens freezing in PhotoShop. Now I have a new msg: System Setting Change. Your hardware settings have been changed. Please reboot your computer for these changes to take effect.
    It reboots OK but brings up the same msg. Now when I see it I just click the X. I made a note of the two display adapters before I started. One was AMD Radeon R5 Graphics and the other I noted as AMD Radeon R7 M340. Second one is now definitely AMD Radeon R7 M440.

    • Sophie Luo

      Hi, John. This problem could usually be fixed by updating your AMD driver.

      I’m not sure which download links to provide you here, since I do not have enough information.

      It is suggested that you use Driver Easy to help you scan for the needed drivers, and then install as instructed. The following is the download link for Driver Easy:

      Please keep us updated so we could see what else we could do.
