Which bios you have? I think different bios versions having different explanation of bios beeps. Your motherboard manual can help you with this. Look for the manual that came with your motherboard, or look for the manual of the official site of your mobo manufacturer.

There s no standard for Beep codes , because every manufacturer has created their own, so as suggested above you should refer to mobo manual. Because of this it is important to find out which BIOS you're using before consulting following codes.
