    As the topic says, I opened Task Manager (WIndows XP Home Edition) and the "System Idle Process" is listed and is using anywhere from 80-99 CPU! it's weird......cause my other Windows XP Home box doesnt have this (tho, the other comp is a HP Pavillion :p) It only uses 20k memory, but that CPU number is worrying me, cause games tend to be really laggy :(

    any ideas?

    The system idle process is what is refered to as a sentinal process. It basically gives the CPU something to do when it does not have any other processes scheduled (this allows nicer code in the scheduler, since it does not have to have special cases when there are no runable/ready processes). Also, this process can be useful from an OS cleanup point of view (looks for deadlocks, etc.)

    It runs at the lowest priority, and so will get cycles when nothing else is requesting CPU attention. So if you are not doing anything, then it is perfectly normal for it to have high CPU usage

    Essentially what this means is that #'s as high 99% are perfectly normal so if game playing is laggy you need to look elsewhere for the solution.I would look first at disabling startup items that you don't need to start on bootup.Having too much stuff in there can slow your system down dramatically.The only things I allow to start on bootup on my machine are my anti virus and firewall.

    Also go here:http://www.blackviper.com/WinXP/servicecfg.htm
    and check out the service configurations,there are a lot of services that you can disable to help your system run better and faster

    And I would also look into new drivers.
