    have you used good thermal paste on the cpu heatsink ? Is the cpu fan working correctly ? Its also worth checking that the cpu voltage is not set too high in bios settings.

    The CPU won't overheat so quickly you cannot enter the BIOS if it has proper thermal interface and a heatsink/fan that is functioning properly. P4's throttle so well I've seen ones run without a heatsink still function.
    You can monitor the core temp with any of several utilities or the hardware monitor in the BIOS. Core temp, real temp, speedfan, etc.
    Is the BIOS delivering the correct vcore for the CPU?
