    Continuous beeping without pause Serious system related problem such as CPU overheating

    If this is indeed true then open the case, turn-on, and carefully look if the CPU Fan is spinning if not shut-down and replace the CPU Fan and/or heatsink assembly. You MUST clean the old thermal paste-off and use cotton swabs and moisten the swab with rubbing/Isopropyl alcohol, apply a thin layer of thermal paste and install the new CPU cooler.

    Good Luck!
