    Check the running processes with top and ps.
    If you have identified the ones causing load, judge if this is expected or even wanted.
    You must always face the curtain with a bow.

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    What Irithori said. What applications do you run? I have some useful, but flaky programs that do this occasionally (and randomly) and have to be killed manually. The "top" command is useful to find these applications.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!

    When this happens (usually when my system is super cold! ) I find the top command 'I' very helpful.
    Also "kill -1 <pid>" *sometimes* suffices.
