This is normal operation for this motherboard. Below is a description of what each beep is for.
1st, and 2nd beep: Checking Power Management Support. If these beeps are heard, Power Management is OK.
3rd beep: VGA function. If the 3rd beep is heard, the Video functions are OK.
4th beep (optional): Checking Power Management Support (again). If the 4th beep is heard, Power Management is OK. The 4th beep will only occur when a system is powered off, then back on. The 4th beep does not occur during a "warm boot" or reboot.
