okay,one beep is normal during the start up.
in order to find out the failure,it depends on the lenth of the beeps you hear. are they long-short-short-long,short-short-short,etc...?

i'll try to find a list or i'll translate one.

What do the various "beeps" mean...?

When you power on a computer the BIOS immediately takes control of the computer and performs the P.O.S.T (Power On Self Test). At the end of the POST the computer will play an audible 'BEEP' through either the PC's internal speaker of through speakers attached to the sound card (if you have a built-in sound chip). If the POST completed successfully without detecting any problems with then system will play a single short beep to let you know the test is complete and the computer will continue to startup and load the operating system.
If during the POST the BIOS detects a problem it will normally display a visual error message on the monitor explaining what the problem is. However, if a problem is detected before the BIOS initializes the video card, or a video card is not present or not detected then the BIOS will play several 'BEEPS' through the speaker to let you know there is a problem. Depending on the type of the BIOS you have the BIOS may play beeps in a specific pattern to indicate what the problem is, or play the same beep a number of times indicating the problem. It is very important that you pay close attention to the number and/or pattern of the beeps your computer plays on startup.

 
Below is a table of the most common AMI, Phoenix and Award BIOS beep codes.
 
AMI (American Megatrends International) BIOS Beep Codes.
AMI BIOS uses beeps of the same length and pitch. The error is displayed as a number of beeps. For example, 4 beeps indicated a timer failure.
BEEP CODE  MEANING  POSSIBLE CAUSE 
1 Beep (No video)  Memory refresh failure  Bad memory
2 Beeps   Memory parity error  Bad memory
3 Beeps   Base 64K mem failure  Bad memory
4 Beeps   Timer not operational  Bad motherboard
5 Beeps  Processor error  Bad processor
6 Beeps   8042 Gate A20 failure  Bad CPU or Motherboard
7 Beeps  Processor exception   Bad processor
8 Beeps  Video memory error  Bad video card or memory
9 Beeps  ROM checksum error  Bad BIOS 
10 Beeps  CMOS checksum error  Bad motherboard
11 Beeps  Cache memory bad  Bad CPU or motherboard


   
Award BIOS Beep Codes
Award BIOS uses beeps of varying duration. A long beep will typically last for 2 seconds while a short beep will last only 1 second. Award BIOS also uses beeps of different frequency to indicate critical errors. If an Award BIOS detects that the CPU is overheating it may play a high pitched repeating beep while the computer is running.
BEEP CODE  MEANING  POSSIBLE CAUSE
1 Long, 2 Short  Video adapter failure  Bad video adapter
Repeating (Endless loop)  Memory error  Bad memory or bad connection
1 Long, 3 Short  Video adapter failure  Bad video adapter or memory
High freq. beeps (while running)  CPU is overheating  CPU fan failure
Repeating High, Low beeps  CPU failure  Bad processor


 
Phoenix BIOS Beep Codes
Phoenix BIOS uses beep code patterns to indicate problems. In the table below the '-' indicates a brief pause between beeps.
Example: 1 - 1 - 2  would sound like BEEP <pause> BEEP <pause> BEEP BEEP

You did ask....

Not quite sure I'm a Quote:
but, none the less, I'm glad to help a friend.


By the way, I hope this request isn't due to an ailing motherboard on your part???
