• 2 short beeps
Error - an error code is displayed on the screen;

-This problem is caused by a serious failure in any component, that the BIOS was not able to identify the problem is usually on the motherboard or the memory modules.
• Continuous beep, repeated short beeps.
-Power supply,
-System Problem,
• Do not beep.
-Power supply,
