atikmdag.sys error BSOD on startup

5 days old system.
hardware config:
Intel Core i7 3770K
Asus Maximus V Extreme
8GB G.Skill Ripjaws 2133Mhz
corsair neutron 240gb ssd
AMD Radeon HD 7970x2

everything works fine in safe mode or with the GPUs disabled and eyefinity disconnected. But when I installed drivers and restarted the system i will get a BSOD at startup indicating "atikmdag.sys" or "atikmpag.sys" as the cause.

IS IT A FAULTY GRAPHICS CARD OR MOTHERBOARD PROBLEM?

    Try imple things first!
    1st.
    boot into the bios and look at the bios rev on the main screen. asus on the older bios switch from a .rom to a .cap file. the newest bios has a lot of bug fixes and for windows 7/8. the other bug fixes are for ram and cpu code updates. there a usb flashback port to flash your mb without powering the mb on or put the new .cap file on a usb stick and use the bios updater inside of the mb bios. also make sure from the mb installer cd you did not install the Lucid Virtu Software V1.2.108.18765 for Windows 7 32bit & 64bit. it a know issues to crash windows and gpu when it tries to bond a ipgpu with a gpu.
    i would also boot into safe mode..uninstall the ati drivers..get windows to boot into windows normal then install the newest intel chipset drivers then reboot. then try the ati drivers again

    If not working try this:
    2nd.
    Follow every step :
    Step 1: Download and install the latest ati graphic driver.AND DONT TURN OFF OR RESTART YOUR COMPUTER AFTER INSTALLATION

    Step 2: Then go to C:\Windows\System32\Drivers and rename atikmdag.sys to atikmdag.sys.old.

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

    Step 4: Copy the file to your Desktop directory.

    Step 5: Open cmd.exe by going to Start -> type cmd in the search box and hit enter.

    Step 6: Change the directory to Desktop by typing chdir Desktop.

    Step 7: Then, type EXPAND.EXE atikmdag.sy_ atikmdag.sys. Or,

    expand -r atikmdag.sy_ atikmdag.sys

    Step 8: When the expansion is complete, copy the new atikmdag.sys from your Desktop to

    C:\Windows\System32\Drivers

    Step 9: Restart your computer and the problem should be resolved.

    Its not faulty mb or card problem! The drivers is the main culprit here!


    FACED SAME PROBLEM 5 MONTHS AGO. Lucky me! Solved that with the 2nd method. Try it carefully.


    WHY ARE YOU POSTING SAME QUESTION TWICE. YOU ALREADY POSTED A THREAD ON MOTHERBOARD SECTION. AND I REPLIED. THEN WHY AGAIN IN GRAPHICS CARD SECTION?
  2. i would check the motherboard bios is set for pci-e first on the graphic card and what is the name and model of you psu with the power he give ? the graphic card could be defective did you plug the power cable on from the psu ?
  3. KAIJER: Sorry, extremely sorry, i was really confused about which one is the best section for posting my question. And i don't know that every part of the forum is inter connected.

    scout: I'm using Corsair 1200i PSU. I checked both of the cards one by one on a different machine. they are working fine. i tried to run a GTX 600ti on my system. surprisingly, its also working fine.
  4. what happens if you only try one at the time and for using both card together did you install the crossfire driver .
  5. tried. With every 7970 there is a BSOD but with 660ti there is nothing. installed crossfire x driver with two cards in the system again BSOD. :( :( :(
  6. Did you tried the method i mentioned above? It worked with my problem. you can also give it a try. Hardly its going to take 15mins of your time.
  7. yeah going to try.
  8. KAIJER: Tried, looks like its working. restarted my system 5 times, turned off and turned it on again. But no BSOD ! Wow. thanks a lot ! :bounce: :bounce: :bounce:

    but seems like i have to do it every time after installing a new driver. This is really annoying! is there any permanent solution?
  9. unfortunately, NO. we can only hope that AMD will fix that bug on the upcoming drivers. Till then JUST UPDATE THE DRIVER IN DEVICE MANAGER. hope that helps!
  10. thanks !

    FOR step 3...ITS LOCATED IN C:/AMD/AMD_CATALYST14.3BETA "or your version" /PACKAGES/DRIVERS/DISPLAY/WB6A_INF/B169191 then in the list there is atikmdag.sy_

    For any one that can not find it :)


  12. I had the same problem like a week ago on Windows 8.1.I just opened the case and cleaned everything and also replaced the psu as the old one was broken and I haven't got the error after that CX. You should try to clean your PC maybe
