  2. CPU at 99%

    Hello,

    To better assist you with your concern, we would like to ask you a few questions:

    • When you start your computer, is the CPU usage already at 99%?
    • Do you have programs on your startup items?

    Regards.

  3. CPU Fan runs constantly

    Hi,

    We would like to know the following information to assist you better regarding CPU fan issue.

    • Does the fan runs constantly fast or do you hear any noise?
    • Have you tried updating all the drivers of your computer?
    • Have you tried any troubleshooting steps before posting this concern? If yes, what are those?
    • What is the memory/disk usage in task manager?

      You may check this by typing Task Manager in the search box
      and hit Enter. Check which application
      is taking more memory or disk usage.

    Looking forward to your response.

    CPU constantly at 99%

    High cpu usage by dwm.exe

    I'm having the same problem. All of the steps listed above did not help. I'm constantly running at least 18% CPU on the desktop window manager with nothing open. My cooling fan is running wide open all of the time.
