    BSOD DPC watchdog violation

    Hey there!

    It's the first time I got this blue screen, I don't know if it'll happen again.

    I searched for it on google and I didn't understand very well why it is caused. Anyway, I haven't updated my drivers yet, could it be the problem?

    thanks in advance!

    This is a relatively rare BCC.

    I would start by updating the below drivers as there are at least 3+ years old.

    How To Find Drivers:
    - search Google for the name of the driver
    - compare the Google results with what's installed on your system to figure out which device/program it belongs to
    - visit the web site of the manufacturer of the hardware/program to get the latest drivers (DON'T use Windows Update or the Update driver function of Device Manager).
    - if there are difficulties in locating them, post back with questions and someone will try and help you locate the appropriate program.
    - - The most common drivers are listed on this page: Driver Reference Driver Reference
    - - Driver manufacturer links are on this page: Drivers and Downloads

    Also this is a suspicious driver that has no information in a google search. I would download Malwarebytes and run a scan just to be sure.

    I attached the log. Found only one thing, but I don't think it is related to MpKslaed74c00.sys. I have no idea of what that thing might be.

    That file might be a MSE definition file. I would rename it to MpKslaed7400.bak

    Your only MBAM indication is

    HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\NTVDM.exe (Security.Hijack) -> No action taken.

    If you are still BSOD'ng upload the DMP files.

    Win8.1Pro - Finally!!!

    Microsoft Security Essentials (MSSE) uses MpKslnnnnnnnn.sys as dynamic driver names. The "n" represents random letter/number combinations.

    Normally you won't see these drivers unless MSSE is doing something during the crash. They can also remain if MSSE is corrupted and doesn't unload them properly.

    Since MSSE is free, the easiest solution is to:
    - download a fresh copy of MSSE
    - uninstall the current copy of MSSE
    - check Device Manager to ensure that these drivers are Uninstalled (in most cases they will be)
    - then install and IMMEDIATELY update the fresh copy of MSSE

    Thanks, guys!

    Seemed a little random that BSOD. It was the only time I saw it.
