    BSOD, error IRQL_NOT_LESS_OR_EQUAL, ntoskrnl.exe


    I am getting a BSOD since one week randomly with the message IRQL_NOT_LESS_OR_EQUAL. BlueScreen Viewer showes me, that it is caused by the driver ntoskrnl.exe. Before I got this BSOD I updated my Windows 8.1 to Windows 8.1.1 . Since this time, this error happens randomly!

    My system specs are the following:

    Laptop: Asus S400 CA
    CPU: Intel Core I5 3317 U @ 1,70 GHz
    Memory: 8 GB
    Graphics: Intel HD Grpahics 4000
    Mainbord: Asustek S400 CA
    Antivirus: Avast! Internet Security (Version: 140512-0)

    Before I got this IRQL_NOT_LESS_OR _EQUAL error I also got the BSOD Driver_Power_State_Failure. I figured out, that it might be the Bluetooth Driver, as buescreenviewer stated the driver causing the error is btfilter.sys.

    I attached also a SF Diagnostic Tool File!

    I would be glad and happy about some help, since BSODīs are annoying

    Thank you very much

    Cheers Fabi

    Your two latest dumpfiles blames Probably caused by : WinFLAdrv.sys ( WinFLAdrv+34f2 )
    This is the driver Related to WinFLAdrv.sys Service Application from and probably related to Folder Lock 6.

    You have many other older drivers which probably need to be updated to windows 8.1.

    Please update these older drivers. Links are included to assist in looking up the source of the drivers. If unable to find an update, please consider it could be a possible/potential BSOD cause or remove (un-install) the program responsible for that driver. DO NOT manually delete/rename the driver as it may make the system unbootable! :

    Note: first check the support/driver downloadsite of your OEM model or system (mainboard) for the latest windows 8.1 drivers.
