System error- pegs cpu RRS feed

  • Question

  • Okay i'm sure this doesn't go here but i can't seem to find where it should go.

    NT Kernel and system is taking up no less than 25% of the cpu, and making everything lag. Using process explorer i discovered the thread responsible: ntoskrnl.exe"!KeAcquireInStackQueuedSpinLockAtDcpLevel+0x1e0

    I've tried suspending, killing, and looking at the permission and it always says the same thing: Unable to access thread.

    so far i've tracked to be a driver for new software's "folder lock". I've never installed this program though and have no way of finding it. So i downloaded the windows driver kit, because that way i can examine the data and hopefully at least narrow it down, then google the drivers i think might be it.

    The problem is, however, that when i try to install, it says that microsoft document explorer couldn't install, and then it completely "roll's back" as it puts it, its installation. No matter how many times i try, it does this. Both files SAY they should be installable, but they aren't.

    This is where i'm stuck at. Any help would be appreciated.

    Relevent links are wdk install walkthrough, answer that led me to the problem, company's website

    Thank you in advance for your help

    Lets run a WPT trace on the cpu.  There are two ways to do this.  The easy way (less info) and the hard way ( more nfo).  Lets start with the easier one first.

    In order to diagnose your problem you will need to download and install the below
    When you have open an elevated command prompt and type the following 
    WPRUI.exe (which is the windows performance recorder) and check off the boxes for the following
    First level triage, CPU usage, Disk IO.  If you problem is not CPU or HD then check off the relevant box/s as well (for example networking or registry)
    Let it run for 60 secs or more and save the file (it will show you where it is being saved and what the file is called
    Zip the file and upload to us on Onedrive (or any file sharing service) and give us a link to it in your next post.

  • Hi,

    You mean this may be related to the  "folder lock” software, can you find it in features and programs in control panel?

    Or can you find something in Program files folder?

    Check if you can find the uninstall property in following registry paths:

    HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall

    HKLM:\Software\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall

  • To my knowledge i've never installed the program. it does not appear in the programs folder. I can't find anything called folder lock in the registry, i've looked through all of the different locations of the system file and none of the uninstalls are for this particular thing.

    Hi i found something using the regedit search thing. Only one thing comes up when i have it search for "folder lock" but its a registry that has no information on it so i'm a little afraid to just delete it. I also can't tell where it would be in the folders themselves, regedit won't tell me.
