    I'm hoping someone can help me with this major pain. My computer has been running painfully slow the last couple of days and after looking into Windows task manager it seems the above is the cause of this. I have no idea what it is or it's function but it is a major headache at the moment.

    I had this problem before. try going into add/remove then windows component and turn off indexing.

    That might be the cause.

    System Idle Process uses whatever free CPU cycles are available; it does not interfere with other processes. As suggested run a spyware checker and disbale indexing to see if you can locate the cause.

    I've experiened this problem caused by a virtual DVD driver (Alcohol) having problems mounting a network-based image .. an example of a generic problem drivers can cause if they're having problems mounting removeable media.

    Not a likely scenario, but if you stil can't nail it then may help.

    Quote from liutilities website "the System Idle Process is not a process, more a counter which is displayed in WinTasks used for measuring how much idle time the CPU is having at any particular time. This counter will display how much CPU Resources, as a percentage are 'idle' and available for use. Cannot be killed"
    So if system idle process is showing 100% it means that nothing is using any cpu power and it is all available for use. This is completely normal.

    yes system idle process is supposed to be that high. It's showing what percentage of your CPU is not doing anything at the time so the higher the better.

    EDIT: oops. posted this just as the previous reply said exactly the same thing

    Thanks for the input. After checking through Windows task manager at the bottom it shows cpu 100% usage and the only variable is the system idle process, cannot work out what else it could be.

    Sorry, should have made it a bit clearer, the cpu fluctuates between 0 and 99% in sync with the sys idle proces (registering the same, at the same time)??????????????

    Ah, that's a different story then.
    When task manager shows 100% CPU usage at the bottom, is there defiantely no other processes on the list using the CPU?
    If System Idle Process is showing 100% then CPU usage should be around 0%.

    OK then, when SIP is showing 0% is there any other processes using the CPU? If it is showing 0% it means that something else is using the CPU.
    It maybe that the total cpu usage at the bottom is slightly out of sync with the info above it.

    Have you tried turning off the indexing service?

    Or doing a malware scan, ad ware, trojan scan. try using:

    Adaware: http://www.lavasoftusa.com/software/adaware/

    Spybot: http://www.safer-networking.org/en/download/

    Stinger: http://vil.nai.com/vil/stinger/

    All of them are free and very useful

    I have often seen the System Idle process running high but never at 100 percent. that means there is nothing else running at all and of course with windoze XP thats not possible. there are loads of services running by default. I would expect to see the high 90s on an idle machine. Just running Task Manager will reduce it from 100 percent - it seems to me that you may have something serious....

    My comment assumed it's the System process, not the System Idle process that's being referred to in this thread, clearly the Idle process at 99% is very common. :)

    arrgh - asynch postings...updates landed before I posted but after my last view..

    try sorting the task manager by CPU percentage and then by time used - culprit should show up clearly...

    FYI - cpus only go at two speeds 100 percent (executing instructions) and zero percent (in a wait state). the SIP is the Micros**t implementation of giving you visibility of (a version of) the amount of wait time your CPU is experienceing. This is normally quite high in any extended period on a Windows(or Unix) platform.
