How to identify BIOS beep codes

Recently my friend's desktop computer stopped working and started to give beep sound during start up. As usual, my friend removed the RAM and replaced after cleaning it. But, problem was not solved. Hence my friend called me and found out the problem and solved it. Here I am sharing you the meaning of different beep sounds during start up.

 When ever you power on a your computer the BIOS immediately takes control of the computer and initiates 'Power On Self Test', shortly known as POST. At the end of the POST, you can hear a beep sound through internal speaker. Short single beep means that test is complete and computer will continue the start up procedure. If BIOS recognizes any internal error will give beep sounds indicating the error. Different beep pattern and their solution is mentioned below.

1 beep: No problem and computer will start normal.
1 beep and no video: Memory refresh failure.Restart the computer.
2,3 beep:  Bad memory. Remove RAM and reinsert.
4 beep: Timer not operating. Motherboard problem.
5 beep: Processor error.
6 beep: Bad CPU or Motherboard.
7 beep: Processor exception. Check processor connection.
8 beep: Video memory error. Check graphics card.
9 beep: BIOS error.
10 beeps: CMOS error.
    So, these are main BIOS beep codes you may face. Proper understanding will surely save time and solve the problem. Please share if you have faced beep code other than above mentioned  through comment.
