POST Beep Codes
If your computer successfully finishes its POST (Power-On Self Test), it will produce a single beep. If you hear more than one beep, you should check the following:
2 or 3 beeps - Check the memory modules (RAM). Check if these are properly seated in their slots
4, 5, 7, or 10 beeps - Check and troubleshoot the motherboard.
6 beeps - Check the keyboard or the system's keyboard controller.
8 beeps - Check the video adapter and its memory.
9 beeps - Check the BIOS. It might be faulty or you might need to flash the BIOS with an updated version.
