    bad pool caller / driver no less or equal / ... errors

    Dear Forum Helper

    I am experiencing several BSOD errors (named above) a day. Sometimes other errors appear, microsoft seems to be quite creative in giving error names.

    The problem can appear anytime, and always when I shut down my computer, or when I put it in sleep-mode.

    I have started my laptop in safemode with internet and without internet connection. When restarted in normal mode after having had it in safe mode without internet connection, windows does not want to report an error. Therefore I am guessing it has something to do with a driver related to my wireless / or a program dependent on the internet connection.

    Here is my dumpfile.

    Thanks alot for your help!

    Please try the below steps.

    1. Update Intel Graphics Driver.

    One of the crash dump shows possible issues with the graphic subsystem.
    ugCheck C2, {7, 11c1, 0, fffffa8007ced0c0}
    GetPointerFromAddress: unable to read from fffff8022f9dd168
    GetUlongFromAddress: unable to read from fffff8022f9dd1f8
    GetUlongFromAddress: unable to read from fffff8022f918410
    Probably caused by : dxgmms1.sys ( dxgmms1!operator delete+11 )
    Please run Intel Driver Update Tool and install any driver update it offers.

    2. Update LAN and WLAN drivers.

    As you said in the first post, majority of crash dump shows network related activities prior to the crash happens.

    nt! ?? ::FNODOBFM::`string'

    NDIS.SYS and TCPIP.SYS are network related Windows files so obliviously some network related drivers might be playing a role in the crashes.

    First uninstall Realtek LAN and Intel PROSET Wireless driver and related softwares completely from the system. Then get the updated versions from the below links.

    LAN : Realtek ( WIn8 and Win8.1 Auto Installation Program).

    WLAN :

    3. Uninstall Koshy John Memory Cleaner.

    Reports from net indicates that this software may create issues in some system. Please uninstall it at least as a test.

    If the issue continues, please upload the latest crash dumps with next reply.

    Thanks a lot Anshad. The BSOD seemed to have disappeared by updating the latest lan&wlan drivers.

    I appreciate the hint regarding Intel Graphics Driver. However, the Intel Driver Update Tool seems not want to update the driver...I will try again at a later stage.

    Koshy is deinstalled!

I receive this message at random intervals throughout the day. I think it's because I have recently installed AVG but would like to be confirmed that this is the fault before buying different software.
