High Disk Usage/CPU when computer goes idle.

    Hi, I've tried searching for this problem I've had, but nothing other than
    the "System Idle Process" comes up.

    My problem is that whenever my laptop goes idle (almost the second when the
    screen saver goes on after 15 minutes), I get high CPU and disk usage. This
    has happened ever since I first bought this computer, so I'm pretty sure it's
    not a program I've installed. But, I've tried to turn off or change any
    programs that are set to start on system idle, but it still happens.

    I'm 90% sure it's nothing like spyware or a virus, because I have the latest
    version of McAfee Anti-virus and Firewall, and Ad-Aware. I've tried
    everything I can think of, so I'm thinking it must be something with Vista.

    Any suggestions would be helpful.

    How long have you owned this computer?
    Vista's search indexing can take a few days to "settle in" and really
    thrashes the hard drive until its fully completed it's task.

  3. Vista also runs defrag on your hard disks when it is idle.

    I think I've had this computer for a little more than half a year. But I've
    had to reformat it once, and I tend to leave my laptop on during the night
    with wireless internet on. Also, only about 30% of the HD is used up, and I
    don't make huge changes with any large programs/files, so I'm sure Disk
    Defrag and the Search Indexer would have finished by now.

    I've looked in the Task Manager, and there was like only one program that
    ran on idle that I changed to run an hour after idle, and I didn't see
    anything about the Search Indexer or Disk Defrag for Idle Triggers. So, is
    there any other way to change Defrag and the Search Indexer to not run on
