    BSOD driver_irql_not_less_or_equal


    Hello
    I've been getting this error recently whenever I shut down my computer

    Problem signature
    Problem Event Name: BlueScreen
    OS Version: 6.1.7601.2.1.0.256.48
    Locale ID: 4105

    Files that help describe the problem
    062915-11154-01.dmp
    sysdata.xml
    WERInternalMetadata.xml

    Extra information about the problem
    BCCode: d1
    BCP1: 0000000000000000
    BCP2: 0000000000000002
    BCP3: 0000000000000001

    I tried searching, but it seems it's coming from different drivers....
    I can't tell which one of my drivers is having problems..
    I uploaded my computer info and the minidump, any help would be great!

    It is Avast that caused the BSOD.
    Code:
    BugCheck D1, {1fffa8022, 2, 1, fffffa80241df0e0}
    
    *** WARNING: Unable to verify timestamp for aswStm.sys
    *** ERROR: Module load completed but symbols could not be loaded for aswStm.sys
    Probably caused by : aswStm.sys ( aswStm+4f48 )
    
    Followup: MachineOwner
    ---------
    Uninstall Avast using Avast Uninstall Utility. Use Microsoft Security Essentials as your antivirus with windows inbuilt firewall, and free MBAM as the on demand scanner.

    Download, install and update those, and then run full system scans with both of them, one by one, as teh installed antivirus failed.

    Report us for any further BSOD after doing it.
