Fix atikmpag.sys / atikmdag.sys blue screen errors (BSOD)

Expanding Atikmdag Sys Thumb2 I use a cheap AMD graphic card from Powercolor. At times I would run into the atikmpag.sys blue screen error, but you can easily fix it by extracting the atikmdad.sys from the original drivers

Expand.exe (File Expansion Utility): Correctly Extract Atikmdag.sys !

Microsoft has a built-in file expansion utility to expand certain files. You can expand the original drivers and replace it with your current, fixing any possible problems by restoring the original state. Sounds simple but a few steps are required:

0. Download the latest ATI graphic card drivers MANUALLY from for your specific graphic card. If you don’t know how to do that you can find more instructions here

1. Step Make sure you have the latest AMD ATI graphic card drivers. To do that you would open the AMD Vision Engine Center via the Control Panel, click on Information and then on Software Update – if you have the latest driver already proceed below

2. Step Alright, got the latest drivers but you still get the atikmpag.sys BSOD?

3. Step Download Everything from voidtools and locate all atikmdag.sy_ files on your system

Simply enter atikmdag.sy_ into the search bar

Finding Atikmdag Sys In C Amd Folder

4. Step I had to open the path (one path on two lines below)

  • C:\AMD\Support\12-4_vista_win7_64_dd_ccc\Packages\Drivers\
  • Display\W76A_INF\B136646

5. Step Copy the file atikmdag.sy_ to another folder that is shorter e.g. C:\test or C:\Users\sOliver\Desktop

Two Files Atikmdag Sy And Sys

6. Step Open the command prompt

7. Step Enter C: and hit enter, then enter cd C:\test\ or cd C:\Users\sOliver\Desktop

8. Step Now enter the following command Extract.exe atikmdag.sy_ atikmdag.sys

Note, there is a space between the two filenames, else you will get an error No destination specified for: atikmdag.sy_

Expanding Atikmdag Sys

9. Open C:\Windows\system32\drivers and rename the existing atikmdag.sys to atikmdag.sys.bak

Windows System32 Drivers

Change To Bak File

10. StepCopy the file atikmdag.sys from your desktop to C:\Windows\system32\drivers

11. Reboot your PC

12. You should no longer receive any blue screens. All BSOD’s that are related to atikmdag.sys should be fixed for now.

Alright, now why do you get the blue screen in the first place? I assume that AMD’s driver installer has problem of correctly expanding and extracing the *.sys files. Although the files appear to be identical there could be a permission problem or a dozen of other possible problems

    You have to repeat all steps for atikmpag.sys – so if you fixed atikmdag.sys above repeat all steps for the other file

    If you get a blue screen for any other e.g. atimpc.dll or atikgktxx.dll, atikeclxx.exe, atiode.exe or any other file then do the same

    @mogs I’ve been having the same issue, both with atikmdag and atikmpag and just now did the atikmdag thing as he listed (although on step 8 he says to do extract, but picture of command prompt shows him doing expand, which extract never worked) and i’m going to do the same with atikmpag

    kyle, it’s been a while since I wrote that but I believe that expand is correct, not extract (as you pointed out)

    I also expanded the files and put them in C:\Windows\system32\drivers and other related driver files.

    I can’t remember if that fixed the issue but you can always try a fresh install on a new partition and see if it’s a hardware issue

    Getting the same error

    “Can’t open output file: atikmpag.sys”

    Fresh Windows 7. As far as I read only people with Win 7 seem to have that issue at all.

    “expanded” (it’s like extracting) it with 7zip: at first the same error

    Put it into some different folder and it worked. Maybe it’s a file system shit-god-knows-what, but no real problem

    Hello, I did all the steps you said and after I copied the expanded ati .sys files onto the drivers folder and rebooted, it said I didn’t have any ATI drivers installed. -.-

    i did all the steps you mentioned, it did not work.

    when the videocard is installed, i get all those artifacts then eventually this BSOD. after removing the videocard(HD4670) and used the built-in video card on the motherboard, it works fine. tried driver sweeper as well to remove all graphic/ATI drivers, rebooted the computer, put back the video card, then it goes to BSOD again. note that i did not even install the videocard driver of the videocard and it went to BSOD again.

    ill try to reinstall windows using the built-in videocard, update the motherboard drivers then put back the videocard. ill let you know if this will resolve it.(crossing my fingers!)

    now my question is after all those troubleshooting and it did not work, do i have a bad videocard? its probably 3-4years old.
