PCI Card Forcing Startup?

    Any idea why the installation of a PCI USB 2.0 four port card would cause a machine to automatically startup after shutdown?

    When I go to start shutdown, the shutdown completes but the machine immediately starts up again.

    Once I remove the card the problem is sorted?

    The card is fine in two other machines I tried it in.

    OS is XP Pro.

    Maybe there are some power management settings in the BIOS causing it... some unusual wake-up event.

    I had this with a similar card on a old Precision workstation.
    I moved the card into a different slot and all was OK.

    It typically happens when the bus controller can't power down the bus due to a conflict state with the card - ie, unknown state. A BIOS update will frequently rectify this.

    The machine in question is a brand new Dell Vostro 400 & has the latest available BIOS update.

    It is also dual booting with XP Pro & Vista Ultimate.

    The card problem occurs on both operating systems so it is definitely a machine based issue.

    There are only two PCI slots onboard & the other has an wireless card installed.

    I will have to go through all the BIOS settings again just in case I missed something.

    Thanks for the replies so far & if anyone has any other ideas, please post.

    Alot of BIOS's have a built in feature called 'wake on'. So when you have a network card and try to access it over your network it will boot, the same goes for any other devices you set this option for. Wake on ram, usb, network, keyboard etc. There will be a power managment option in your bios to enable or disable devices from doing this.

    How right you were :)

    In the Power Management of the BIOS there was an option for "Remote Wake UP" & it was defaulted to on. I set it to off & it sorted the problem.

    Thanks to everyone for their input.
