What is video TDR failure (atikmpag.sys)?

While playing a video file, game, etc. you may get a “blue screen” error known as TDR failure. As a result, the computer restarts, but this does make things better, since the video is still not available.

More often than not, the message will look like this: "VIDEO_TDR_FAILURE (atikmpag.sys)".

Generally, the TDR is one of several Windows components, and if it gets damaged, the graphics card stops responding. Then Windows stops and reboots to fix the driver error, which is extremely rare. In such a case, you need to fix the video TRD crash yourself, and here's how to do it.

How to deal with atikmpag.sys failure on Windows 10

In general, you first need to deal with the root cause of TDR video failure.

The source of the problem may be:

1. A damaged video card.

2. Video card drivers that have not been updated for a long time.

3. Too many applications running in the background.

4. Driver incompatibility.

In order for your video files not to be permanently damaged, you need to fix this error as soon as possible.

Method 2: Tweak your Power Management settings

In Settings, you can disable the PCI Express function. Go to the “Hardware and Sound” section. Then select “Power Options” and click on “Change advanced power options”. Select the “PCI Express” option and turn off “Link State Power Management”. Confirm the changes by clicking on “Apply” and “OK”.

Method 4: Replace atikmpag.sys

If you have an ATI or AMD graphics card, you can try this method:

• If you haven't already, download the latest drivers for your card from the manufacturer's website.
• Navigate to the hard drive (C :) >> Windows >> System 32 folder and then enter the Drivers folder. Locate the file “atikmdag.sys” or “atikmpag.sys” (depending on which error you get) and add “.old” after the current file.
• Copy and paste the file to your desktop.
• Open Command Prompt with administrator rights and type “chdir desktop”, then press Enter.
• Next, depending on the renamed file, type: “expand.exe atikmdag.sy_ atikmdag.sys” and press Enter; or type: “expand -r atikmdag.sy_ atikmdag.sys” and press Enter.
• After that, copy the new atikmdag.sys or atikmpag.sys file from your desktop to the Drivers folder in System 32 and safely restart your computer.
