Detecting Computer Error Beep Of Sound

Detect errors from the sound BeepBeep computer (motherboard speaker's voice) is often used as a standard way to detect the damage on the motherboard. Indeed, every motherboard (more precisely each BIOS) sometimes use a different sound when the computer booting.

The difference is what you should know to prepare for your computer errors. Even so, listening to beeps are not the only solution, but at least with the sound of it you will know the next step in the process of improvement.

Beep Code following standardization my coffee from one of a collection of hacking articles. However, once ayang, the source of the following articles I do not find on the internet. But, thanks a lot for the creators.

AMI BIOS Beep Codes
Code Explanation

1 Short Beep System OK
2 Short Beeps Parity error in the first 64 KB of memory
3 Short Beeps Memory failure in the first 64 KB
4 Short Beeps Memory failure in the first 64 KB Operational of memory
or Timer 1 on the motherboard is not Functioning
5 Short Beeps The CPU on the motherboard generated an error
6 Short Beeps The keyboard controller may be bad. The BIOS can not switch to protected mode
7 Short Beeps The CPU generated an exception interrupt
8 Short Beeps The system video adapter is either missing, or its memory is faulty
9 Short Beeps The ROM checksum value does not match the value encoded in the BIOS
10 Short Beeps The shutdown register for CMOS RAM failed
11 Short Beeps The external cache is faulty
1 Long, 3 Short Beeps Memory Problems
1 Long, 8 Short Beeps Video Card Problems
