    Sounds like you have two issues to me. One is heat and the other is acpi.

    concerning heat: make sure the cpu heat sink is firmly fastened and the fan
    is working. If the cpu overheads the mainboard will autoshutdown to protect
    itself. Check all fans in the system. If, when the case is closed, the
    power supply fan air feels hot consider adding another exhaust fan to the
    case. Make sure the case has airflow all around it and you are not boxing it
    in a desk cubby with no ventilation out the back.

    The acpi [not being able to do sleep] can be related to the power supply,
    mainboard or bios configuration. You must make sure in the bios that acpi is
    enabled before installing XP. Otherwise the hardware enumeration in the OS
    will NOT include the ability to autoshutdown or do any of the other things
    associated with acpi.
