    When I press power button, all light on motherboard turn on for a few second ,but no beep, then it auto shut off the whole pc, then it auto turn on again, beep, and boot normal. I don't know why there 's an shutdown after power on the pc first time.

    I had the same problem sometime ago, but I wanted to overclock the cpu , the pc restarted for the second time and it would only run on default settings.
    Did you overclock your hardware?

    The turn on, shutoff, then turn on with beep is the process the ASRock motherboard takes when overclock settings are changed and then applied. Your motherboard is setting overclocks on startup every time for some reason. Reset your BIOS to defaults, remove and reset the CMOS battery, and then reapply your overclock. You may need to tone it down a bit.

    Ensure you test the system at stock clocks and voltages first, to see if it continues to do this after 4 or 5 boots.
