I cleaned my computer last week; I remove all the hardware components of it because I want to remove all the dust that it has.
When I re-installed all hardware components of the computer and start powering it on, I hear endless beep sound so I immediately turn off the AVR.
I called my cousin and let him check what the cause of the beep sound. He said that the memory was not properly placed on the memory slot.
He also said that when a computer emits a sound, it tells you that there is something wrong inside the computer. So my only concern is that, what are the different interpretations for these beep sounds?
So I will know what to do if I encounter this again.

The beep sound that you hear whenever you power on your computer is the POST or the Power On Self Test. You may here 1 or 2 beep codes depending on what kind of BIOS you're computer have.
The purpose of POST is to make sure that your computer has the minimum requirements and it has necessary hardware components to make your computer running properly.
Here are the common beep codes depending on the BIOS manufacturer.
AMI BIOS
Beep Code/s – Meaning
1 short beep – Failure on DRAM refresh
4 short beeps – System timer failure
5 short beeps – Failure on Processing
6 short beeps – Keyboard failure
7 short beeps – Removable devices Error ( USB, Floppy etc)
AWARD BIOS
1 long and 2 short beeps – Video card error
2 Other beep sounds is related to computer memory problem.
IBM BIOS
1 short or 2 short beeps – computer POST
Endless beeps – Power failure, Loose Card.
1 long and 1 short beep – Motherboard problem
3 long beeps – Keyboard error
Knowing these common beep codes will help you to determine the problem on your computer.

The problem may be as a result of assembling the hardware components wrongly, and therefore you will need to check where you could have gone wrong and rectify that. Use the procedure below to troubleshoot:
-
Locate the front USB on your computer.
-
Unplug it.
-
Unplug the front hub connections too, because they may be grounding the computer.
-
Once you have done that, plug in the power switch and see if the problem is resolved.
Also try the following:
-
Locate the RAM on your computer.
-
Pull them out and then clean them, they could be covered in dust that is preventing them to be recognized.
-
Plug back the RAM, and then restart the computer.
-
See if everything works fine.

The beep codes can determine the error of your computer by listening to it, but it depends on your  BIOS manufacturer so kindly see what is your BIOS manufacturer.
I will site some bios manufacturer beep codes:
 AMI BIOS beep codes
Â
1 short- DRAM Refresh failure​
2 short -Circuit Parity error/failure in base memory
3 short-64K RAM failure
4 short-System timer failure
5 short-failure on process
6 short -Keyboard Gate controller A20 error
7 short-General exception error caused by damage expansion card or the motherboard it self.
8 short-Failure in display read/write memory
9 short-failure ROM BIOS checK
10 short-error CMOS shutdown register Read/WriteÂ
11 short-Cache memory test failed
1 long, 3 short- Failure in Conventional/Extended memoryÂ
1 long, 8 short -Display/Retrace failed
Â
IBM BIOS beep codes
Â
No Beeps-Power supply/disconnect speaker / Loose Card, or Short.
Â
1 Short Beep-computer system is ok.
2 Short Beep-POST error.
Continuous Beep -No Power/Loose Card, or Short.
Repeating Short Beep-Power supply or keyboard
1 Long and 1 Short Beep-System board error.
1 Long and 2 Short Beeps-Display (MDA, CGA) error .
1 Long and 3 Short Beeps.-Video Display Circuitry.
3 Long Beeps- 3270 keyboard card errorÂ
1 Beep, Blank – Video Display Circuitry.
This codes will help you determine the error of your computer.

Hi Bruce,
In computer terminals, the ASCII character code 7, bell character outputs an audible beep. The beep is also used to notify the user when the BIOS is not working or there is some other error during the start up process often during the power-on-self-test (POST). Beep is also produce when many keys are press at the same time, manifesting that the computer often cannot handle the process. One beep means computer is normal. Two beeps means POST/CMOS error.
One long beep with one short beep means there is motherboard problem. One long beep with two short beeps means there is video problem. One long beep with three short beeps means there is video problem. Three long beeps means there is keyboard error. Repeated long beeps means there is memory error.
To interpret what three beeps mean, you will have to find out the BIOS type of the computer which appears on the screen during start up. Otherwise, check the motherboard type to find out.

You control on your workstation as natural and wait long-sparingly as it goes during its set up a habit.
However, to your alarm, in its place of the in service system booting in precisely, To number out what do 3 beeps mean on startup of a processor, you will contain to first shape out the BIOS type of the computer. It appears on the screen during startup.
If you can't see the startup monitor, you can find the BIOS type, from the information about the motherboard type. In the rest of this article, you will find a decade counter for the majority of the usually used BIOS firmware, install on computer motherboards.

If you are hearing beep codes right after you turn on your personal computer, it usually means that the system has experienced some sort of issue just before it was able to show any kind of error details on the monitor.
Step 1: Switch on the power of your computer.
Step 2: Pay attention to the beep codes that sound when the computer begins to start.
Restart your computer if you want to hear the beep again. You are not probably to develop whatsoever problem you have worse by restarting a few times.
Step 3: Jot down, in any way that makes sense to you, how the beep sound.
Step 4: Choose the correct beep code depending on your motherboard's BIOS manufacturer.

There are different interpretation when hearing beep codes on your computer. And yes, often times, the reason for it is an issue with the memory card. Beep Codes meaning also varies depending on which Motherboard BIOS Manufacturer you are using such as AMI, AWARD, Phoenix, IBM, and Mac. Beep codes are to report specific initial issues with your system. Since you disassemble your CPU and you are hearing beep codes after turning on your computer, it could be that your system encountered an issue before it can show any error information on your monitor.
Here are the meaning of the beep codes in your computer.
It is important that you identify which BIOS are you running and then check on the meaning of the beeps. Since you said you are hearing an endless beeps, it could be a RAM problem. To fix this, try to reseat your memory. Just remove the memory and then put it back to the slot again. Or if you have two memory installed, try to swap the location of each memory or move it to another slot if you are using one memory.

Hi Bruce,
I've experienced it, I am a Computer technician and i know what's your problem:
Heres the steps:
1. Unplug you AVR and power cords at the CPU
2. Open your CPU, remove your RAM, if the gold plates of the Ram is dirty, use an eraser (pencil eraser) and wipe it with a clean cloth using only one direction.
3. If you have a clean paint brush or vacuum cleaner for the RAM slot then it'll be useful, if you only have paint brush it in one direction, so that the dust would be wiped away.
4. Insert your RAM to your slot make sure it Clicks! and it locks.
5. Connect all wires, close your CPU.
6. Plug your AVR and try to turn it on. If problem still persists, you have a defective Memory Card.
Hope the steps helped your problem.

How to interpret  computer beeps
When your computer beeps it means there is a problem with the installation or BIOS, the meaning of the beep depends on the brand and version of BIOS used
1. Beep – In both AMI&AWARD , means there is a memory problem
2. Beeps – In AMI, means memory problem
3. Beeps – In AMI ,means memory problem
         – In AWARD, means video problem
         – In IBM means keyboard problem
4 beeps-in AMI means system failure
               In AWARD means video problem
5 beeps – in AMI means CPU failure
Continuous  beeping-in AMI&AWARD mean memory or video problem
In IBM means power problem or loose cord

Based on my research, if the computer makes a beep sound…
There’s different meaning:- ONE BEEP SOUND, means everything on the CPU is normal. TWO BEEPS SOUND, there’s a problem in semiconductor or maybe it has posted.- ONE LONG AND SHORT BEEP, mainboard problem. – ONE LONG BEEP, TWO OR THREE SHORT BEEPS, problem about video- THREE LONG BEEPS, the keyboard has a problem. – REPEATED LONG BEEP, the memory doesn’t function. – CONTINOUS BEEPING, the computer was overheating.
