    Random Windows 8.1 BSOD while browsing - atikmdag.sys


    Hi All,

    Forgive me, I am the n00est of n00bs.

    My relatively new, Black Friday '14 Toshiba Satellite Satellite C75D-B7260 laptop has started randomly and unpredictably crashing to BSOD, with following error message:

    SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (atikmdag.sys)

    This happens maybe once or twice a day at some point in 4-6 hours of computer use. The timing is completely unpredictable. It usually happens while I'm browsing in Mozilla Firefox with multiple tabs, but that is what I do 80% of the time anyway, so I doubt that's a factor. I've also watched hours of Netflix via the Windows 8 app, without any crashes.

    The computer says it'll restart itself, however even after waiting as much as 30 minutes, it never does. I inevitably have to manually power the computer off and then start it again.

    I've searched the atikmdag.sys error extensively in various forums, but have been very hesitant to follow solutions proposed as none of the problems seem to be an exact duplicate of my own. I am terrified of accidentally blowing up my computer by uninstalling or replacing drivers.

    Plus, there are a million drivers for this model on the Toshiba website alone (Drivers & Software Support | Toshiba), so I don't know where to even start.

    I get sweaty with nerves whenever I use my computer now, so any help would be hugely and eternally appreciated!

    - Christina

    If using TAP-Win32 Adapter V9 or OpenVPN driver remove it please.
    I would suggest you to uninstall the currently installed AMD Driver using the Display Driver Tool from this **LINK**. Once it has removed the drivers, reinstall the latest drivers from the AMD Website and see if the crashes persist or not.

    Hi, thanks for the super-fast response!

    1. I think I correctly uninstalled Private Internet Access (the VPN program I use on open wifi networks), and deleted TAP-Win32 Adapter V9.

    2. I installed the AMD Driver Autodetect from here (AMD Driver Autodetect).

    3. I ran the AMD Driver Autodetect, which said I needed to download "amd-catalyst-omega-14.12-without-dotnet45-win8.1-64bit.exe" (screencap)




    4. I clicked "download," then went and found the download in the folder noted (screencap). I double-clicked to run the app, but...

    5. I got this error message that "this app can't run on your PC"

    Now I feel totally stuck, no idea what to do!

    Last, I ran the DM Log collector tool again to track possible changes? I don't know if that helps or not, but I thought it couldn't hurt?

    Okay, I grabbed this AMD Display Driver from your link: Satellite C75D-B7260 Support | Toshiba

    I guess at this point, I wait and see?

    If I may ask, most of the time I have to have my computer on an open and extremely vulnerable wifi network, which is why I was using a VPN (a pay VPN, no less!), https://www.privateinternetaccess.com/.

    I uninstalled per your instructions, but is this something I can reinstall?

    I wouldn't recommend it (while we are troubleshooting). After we sort out the crashes. Feel free to do whatever you want. If BSODs reappear, you'll know what's causing them.

    Okay, thanks very much!

    I'll try to stay off the open wireless for a few days and stick to my personal cellphone hotspot. No Netflix!

    The BSODs weren't reliable, so I'll have to test for 3-5 days before I'll know if we've healed it.

    I'll certainly be back to let you know either way, and to donate to DDU if appropriate.

    Thanks again so much! You're an angel!

    Okay! Update time! No BSODs, since my last posting, although I didn't turn my computer on during the weekend. But I was on the internet for about 4-5 hours a night, browsing and using the windows 8 Netflix app with zero problems!

    Then I tried to reinstall Private Internet Access VPN about an hour ago. As soon as it finished installing and I opened PIA VPN started to connect...

    BAM!!!

    BSOD: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (atikmdag.sys) all over again!

    I'm too n00by to declare with confidence that's the culprit, but it seems unlikely to be coincidental.

    I repeated exactly all the steps outlined above to get ride of Private Internet Access VPN and reinstall the AMD driver.

    Then I contacted PIA VPN customer service. They appear to be blaming the problem on Kaspersky, or possibly IPv6. I linked to our exchange here to give them the background. This was our chat support session:

    Jason W: If you are getting a BSOD there could be corruption in your windows install, or a service running in the background conflicting with our software.

    Jason W: Did you run the installer for our application as administrator?

    Me: Yes, I did. After uninstalling PIA, I didn't have any BSOD for almost a week. Then, tonight, I reinstalled and within minutes of opening PIA I had the same BSOD.

    Jason W: Do you have any anti-virus, firewall, or security software installed on your computer? It is possible this could be interfering with the VPN connection.

    Me: Yes, I'm using Kaspersky. The VPN connection itself seemed to work great with Kaspersky until the BSOD started happening. The diagonistics don't seem to indicate the security software is the problem. atikmdag.sys BSOD is an AMD display driver issue.

    Jason W: Our application runs as the following executables found inside c:Program Files pia_manager
    openVPN.exe
    pia_manager.exe
    tapinstall.exe
    installer_win.exe
    pia_tray.exe

    Can you ensure that none of these are being blocked or filtered by your security software? You may need to add them to your exclusion list in your anti virus software.

    Me: I actually have PIA completely uninstalled at the moment, so I'm unable to check. I might test for another week to see if having PIA off my system prevents BSODs, then attempt to reinstall a final time. Any tips for that?

    Jason W: Be sure run the installer as administrator.

    Jason W: 1. Download a fresh copy of our software: https://www.privateinternetaccess.co..._installer_win 2. Right-click on the installation file, and choose Run as Administrator. 3. If the App installs successfully, go to Start and Locate Private Internet Access 4. Right-click on the Private Internet Access program file, and choose Open File Location. 5. Right-click on the Private Internet Access shortcut in the resulting folder, and choose Properties. 6. Go to the Compatibility tab at the top, and enable the option "Run this program as an administrator" at the bottom of the window. 7. Apply all changes, and say Ok out of any windows remaining open.

    Jason W: There are two common compatibility issues with our software in Windows 8. The first is IPv6. IPv6 seems to cause connection issues with our VPN service, so we recommend disabling it. Instructions on disabling IPv6 can be found here: Disable IPv6 on Windows 8

    The other common fix to issues with our software in Windows 8 is to set the client to run in Compatibility mode for Windows 7. To do this: Go into Program Files (not Program Files x86) and look for the pia_manager folder. Open it. Right click the pia_manager.exe and click troubleshoot. Choose the option, "This program worked in a previous version of Windows" When asked what version of Windows the program worked in, choose Windows 7 Test the program now, and close the troubleshooter. Reboot the computer, and test again.

    My question is, it worth trying to follow these instructions? Do either of the tech's suggestions have a possibility of working, or is he just giving me boilerplate advice?

    If not, is there a VPN solution that you personally like or recommend? I have to be on a public business wifi for a goodly portion of each day, so ideally I need a very portable hardware or software solution.

    Thanks again so kindly!

    The culprit is indeed AMD's driver. However, you stated that it only occurs when connecting to their VPN? The driver could be "calling" the AMD driver causing it to crash. You can try adding these files to exclusions (but you usually get a warning if and when something is blocked). Unless you have your AV in Gaming/Silent mode however you want to call it. The part with compatibility issues is really worth a shot. I am personally using Cisco VPN on three of my computers and I have to run it in compatibility mode for W7 and as Admin or else it refuses to connect, but it doesn't give me a BSOD if the connection fails. If nothing helps try uninstalling it and testing your computer without it. If it doesn't crash, that's very likely to be the culprit. Thanks for keeping me updated.
    Kind regards,
    Mihael
