    Acer AS5532-5535 laptop, purchased November, 2009.

    When booting, the laptop CPU was at 100% for 10 or 15 minutes. No one process was responsible. Every little process was consuming 30-50% of the CPU--taskmg.exe, dwm.exe, explorer.exe, and so on. After 10-15 minutes, it would act normally.

    I tried using msconfig to disable ALL items in Startup, then ALL services. Nothing worked until I used the Device Manager to disable the Ethernet port.

    The driver for the Ethernet adapter is from Windows 7. Acer does not provide their own driver for it. When I try to reinstall it, Windows tells me that I already have the most current driver. I have tried removing it to force the driver to reinstall.

    Acer tech support responds with canned, irrelevant answers like "Reinstall USB drivers" and "How to use System Restore Points".

    What should I try?
