Table of diagnostic beep codes compiled by AMI BIOS during power-on self test[8][9] Number of beeps

Meaning
1 - power-on self test successful
2 - Parity error in the first 64KiB of RAM
3 - Memory failure in the first 64KiB of RAM
4 - Same as 3, but also including a non-functional timer 1
5 - CPU error
6 - Error in the A20 line on the 8042 keyboard controller chip
7 - Generation of a CPU virtual mode exception signifying an error
8 - Read/write error when accessing system video RAM
9 - Mismatch between the calculated checksum of the ROM firmware and the expected value hardcoded into the firmware.
10 - Read/write error for the CMOS NVRAM shutdown register
11 - A fault in the L2 cache

9 BeepsNine beeps means that there has been an AMIBIOS ROM checksum error. Literally, this would indicate an issue with the BIOS chip on the motherboard. However, since replacing a BIOS chip is sometimes impossible, this AMI BIOS issue is usually corrected by replacing the motherboard.
Use utility tool like RegInOut to repair corrupt registry files and keep your computer safe from being damaged.

5 beeps for an AMI BIOS, which I think you have, means you have a processor error, or, in other words, the CPU.
Just to be sure, disconnect everything BUT the video, CPU, and memory. See if the result is the same.

here are some of the basic codes, depending on which BIOS you have...

Also you do not indicate which fan? I would guess you mean the main Power Supply (PS)? In which case it could just be you need to replace the PS.

Here is a link to some other codes as well...

AMI BIOS ERROR BEEP CODES

• 1 Beep - Memory Refresh Failure (check memory)
• 2 Beeps - Memory Parity Error in first 64KB block (check memory)
• 3 Beeps - Memory Read/Write Error in first 64KB block (check memory)
• 4 Beeps - Motherboard timer not functioning (possible motherboard replacement)
• 5 Beeps - Processor Error (may need replacement Processor)
• 6 Beeps - Gate A20/keyboard controller failure (possible motherboard replacement)
• 7 Beeps - Processor Exception Interrupt Error (may need replacement Processor)
• 8 Beeps - Display Memory Read/Write Failure (reseat or replace video card)
• 9 Beeps - ROM checksum Error (replace BIOS chip or motherboard)
• 10 Beeps - CMOS shutdown Read/Write error (possible motherboard replacement)
• 11 Beeps - Bad Cache Memory - test failed (replace cache memory)

Phoenix BIOS ERROR BEEP CODES
Phoenix BIOS beep codes are a series of beeps separated by a pause, for example:
beep --- beep beep --- beep --- beep beep would be 1-2-1-2

• 1-1-4-1 - Cache Error (level 2)
• 1-2-2-3 - BIOS ROM Checksum
• 1-3-1-1 - DRAM Refresh Test
• 1-3-1-3 - Keyboard controller test
• 1-3-4-1 - RAM Failure on address line xxxx (check memory)
• 1-3-4-3 - RAM Failure on data bits xxxx of low byte of memory bus
• 1-4-1-1 - RAM Failure on data bits xxxx of high byte of memory bus
• 2-1-2-3 - ROM copyright notice
• 2-2-3-1 - Test for unexpected interrupts

I hope this helps.

Is it 3 Short beeps? Check your RAM.
I mean, take out the RAM, clean its contacts with an eraser and put it back.
If the problem persists,

If you have many RAM chips, try starting computer with only one chip at a time and thus you can find which one is faulty.

Take the faulty chip and try on some other computer, if same proeblem, that chip is damaged.

Continuous beeps mean that the power supply or motherboard are faulty.

The beeps you hear are BIOS Beep Codes. Sort of a 'Morse Code', if you will. So many short beeps, or so may long beeps, or a combination of short, and long beeps, making up a code.

This is the computers way of telling you something is wrong, and an area to start looking in to find the problem.

BIOS = Basic Input/Output System. A small, (Usually 64MB in size) program that is on the BIOS chip. (Chip is a slang term for Integrated Circuit. The BIOS 'chip' is soldered to your motherboard.
http://en.wikipedia.org/wiki/BIOS )

How to read that BIOS Beep Code? This becomes a little more difficult, as there are two main BIOS program makers, and every series of computers may have a different version of that program. (Award and AMI. Award and Phoenix merged)

HOWEVER, listen carefully to those beeps. Listen for a continuous series of beeps, then a pause, then the series of beeps again.
Compare what you hear to this chart,

A common problem is that ram memory stick/s may have become loose, or the ram stick is defective. (Ram 'stick' is slang for ram module)
Try re-seating your ram stick, or sticks if you have more than one.

The orange light means your harddrive isn't active. That lamp, (light), that you see is the Harddrive Activity Lamp. Red means it's working, (Active), Orange means it isn't.
If you have a ram memory problem, (Ram stick/s), your computer isn't going to work, which means the harddrive won't be working.

Do you get video? If so then it could be a stuck key on the keyboard.

Do you get no video? If so then reseat the RAM.

On a desktop pc u hear continuos beeping it's something to do with da ram so try replacing the ram or reseat the ram for help go to compaq.com

pls try to use another compatible memory stick.

then confirm the status of your micro processor
