    I'm running XP Pro on 2.8 gig Pentium 4 with 2GB memory.

    My computer is running so slow that I started Windows Task Manager and check Applications running,Processes & Performance. Nothing unusual until I came to Performance and saw that it was 100% CPU usage. The computer is idle so it dosen't make sense. I've restarted the computer twice but after a while it returns to 100% usage. I've just restarted the computer to send this message and I've Windows Task Manager Running in the background showing the CPU Usage and it keeps peaking then returning to 10-20%.
    Has anyone any idea how I can find out what is causing this as the computer is unusable when whatever it is kicks in.

    Regards,

    Dave

    Check it's not overheating, or it could be a software problem.

    Let's see what's installed and auto-starting and if any obvious issues need to be addressed.

    Go here and click the green "Download latest version" link to download and save HiJackThis 2.0.4

    After it's been downloaded and saved, close all open windows first, then double-click it to install it.

    Allow it to install in its default location - C:\Program Files.

    After it's been installed, start it and allow its main window to load.

    Uncheck "Do not show this window when I start HiJackThis".

    Click "Do a system scan and save a log file".

    When the scan is finished in 30 - 60 seconds, a log file will appear.

    Save that log file.

    Return here to your thread, then copy-and-paste the ENTIRE log file here.

    Is your computer a desktop or a laptop/notebook?

    What brand name and model name and model number is it?

    Could you identify which process is taking over the processor? I have the same problem with the task manager of my computer. It only shows how much CPU power is being used. But it does not show the responsable to that.

    So what I did, I downloaded the app Process Explorer http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx

    With this you can know who is the responsible causing the total consumption of CPU.
