    svchost CPU spikes

    Installed a machine at work with Vista business.
    From the moment I log on I have a svchost.exe using 70% on core1 and 30% on
    core2 for 2 seconds and then going idle for 4 seconds.
    And it keeps doing that even if I don't have anything open or am doing
    anything.
    In resource monitor it says that the process is: svchost.exe
    (LocalSystemNetworkRestricted).

    Screenshot: http://resource.mezelf.com/taskmanager-vista.jpg
    (The updatespeed was set at high.)

    Machine : Intel C2D 1,8 with 3 GB memory
    Mainboard: Asus P5B-E

    What could be causing this?
    This problem started right after install even. :S

    If you right-click that process svchost.exe in Task Manager, and choose 'Go
    to service', you can see which services it is hosting, which will help you
    to pin down which particular service(s) is/are causing the 'spikes'

    I found that the service runs:
    AudioEndpointBuild
    CscService (offline files)
    hidserv
    Netman
    PcaSvc (prg comp. ass. serv.)
    SysMain (superfetch)
    TabletInputService
    TrkWks (Distr. Link track client)
    UmRdpService
    UxSms
    WdiSystemHost
    WPDBusEnum (Portable Dev. Enu. serv.)
    wudfsvc (Wind. Drv Foundation)


    I could stop all of them except wudfsvc (windows doesn't allow stopping that
    one)
    All didn't help.

    A fear haunts me that perhaps only a reinstall of the machine might.
    As the service tab doesn't show activity as a help to nail down the specific
    process.

    msconfig (Start > msconfig) is a good tool for trouble-shooting that kind
    of issue.

    You could experiment by disabling some of the potential culprits in your
    list (unchecking them via the Services tab), and see if the problem
    disappears with a reboot. If it does then you have your culprit.

    After 2,5 hours and lots of reboots I got it down to 'Plug and Play'.
    Which makes that I will have to life with it unless I reinstall.

    Good job in pinning it down. Might be a particular device that you've got
    attached to your system that's causing the problems.

    Nothing special in the machine:
    Asus P5B (with onboard LAN and audio)
    ATI radeon 550
    and the usual HDD/DVD

    Make sure you have the latest BIOS. Many Asus boards need a BIOS update to
    work properly with Vista.

    Checked the BIOS and it's on the latest version for it.

    Re: svchost CPU spikes

    Hi,

    I'm struggling with a similar problem, exept with me it seems to be the "sysmain" or "superfetch" service. Stopping this service (or disabling it in services.mcs) stops the CPU spikes.

    I just want to know whether or not this service is critical for my PC and of there is some kind of update available to fix this problem.

    Thanking you in advance...
