    welcome aboard.

    It crashed on the display driver....
    Code:
    fffff880`044ae138  fffff880`05be2fefUnable to load image \SystemRoot\system32\DRIVERS\atikmdag.sys, Win32 error 0n2
    *** WARNING: Unable to verify timestamp for atikmdag.sys
    *** ERROR: Module load completed but symbols could not be loaded for atikmdag.sys
     atikmdag+0x136fef
    Update your ATI/AMD display driver.
    You can get it from the link in our forum, Latest AMD Catalyst Video Driver for Windows 7, or you may go to AMD Graphics Driver and Software and opt for Automatically Detect and Install the appropriate driver for your card.


    During installation, you may opt for advanced installation, and install the display driver only, not the Catalyst Control Center.

    Test your RAM modules for possible errors.
    How to Test and Diagnose RAM Issues with Memtest86+
    Run memtest for at least 8 passes, preferably overnight, per RAM module per slot.

    ► Stress test the Graphics Card using Furmark.

    Daemon Tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known BSOD causer. Uninstall Daemon Tools at first. Then download SPTD standalone installer from Disk-Tools.com, and execute the downloaded file as guided below :

    • Double click to open it.
    • Click this button only:
    • If it is grayed out, as in the picture, there is no more SPTD in your system, and you just close the window.

    Free up the startup.


    1. Click on the Start button
    2. Type “msconfig (without quotes), click the resulting link. It will open the System Configuration window.
    3. Select the “Startup” tab.
    4. Deselect all items other than the antivirus.
    5. Apply > OK
    6. Accept the restart.

    Let us know the results.

    @Arc

    I have updated my display driver to the latest one already ever since before I encounter few BSODs.

    I'm suspecting my RAM is a bad RAM that caused all the problems. I have not run Memtest yet but all the BSOD I encountered seems had issue on memory management, for example like ntoskrnl.exe (the most), irql_not_less_or_equal, NTFS.SYS, and currently the atikmdag.sys too.

    So I am wondering is these the signs of bad RAM? I'm using Corsair Vengeance 1600 4GB x 2.

    Thanks for your reply.

    I have found nothing to suspect the RAM strongly, but if you need, you may test your RAM modules for possible errors.
    How to Test and Diagnose RAM Issues with Memtest86+
    Run memtest for at least 8 passes, preferably overnight, per RAM module per slot.

    Have you uninstalled Daemon Tools and SPTD already? Let us know the results after that.

    Yes, I have removed DT and SPTD already. My BSOD it's not "that" frequent but sometimes it is. It's a weird BSOD. Most of the time is ntoskrnl.exe BSOD, any idea for that?

    Owh, not RAM? I'm looking to RMA my RAM also. Any other way to prevent BSOD happen again? ;/

    I can't run Memtest yet since I need to use this machine frequent.

    Thanks

    Run memtest overnight, before going to bed :)

    ntoskrnl.exe is the kernel on which the crash occurs and it cannot be the real cause of a BSOD. Either something is missing by the memory dump, ot it is to do a detailed analysis to find out the cause. There are ways to do it, dont worry :)

    Now observe the situation. Let us know on the occurrence of the next BSOD ... of after a reasonable time that you think.

    So no point RMA my RAM? Then how about clean reinstall a fresh Windows 7 and drivers?

    Thanks, I will post here if I encounter any BSOD again. Make sure you have a look here sometimes too, thanks again Arc.

    If the RAM shows errors in memtest, you must to RMA the RAM. Otherwise, there will not be a valid ground to do it.

    NO ... ntoskrnl.exe is not missing or anything. For it, you need not to do a clean installation. ntoskrnl.exe is not a problem, and never was. It is just lack of memory data on the crash, and nothing more.

    But if you want to do a clean install, you may do it anytime. :)
