What is a Beep Code?
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). This BEEP sound shows the problem faced by your computer.
Troubleshooting Beep Codes
1. Switch ON your computer. If it is already ON, restart your computer or just try to switch OFF and back ON.
2. If your computer produces BEEP sound, listen carefully and note down the codes.
Note: It may be something like “1 – 1 – 2 would sound like BEEP <pause> BEEP <pause> BEEP BEEP” and some computer will produce many beeps with number of beeps or some produce short and long beeps. And all these codes have a meaning.
3. If you cant able to note down the code, restart your computer and again try to note down the code.
4. When you are ready with your BEEP code produced by your computer, you need to find out the BIOS used by your computer.
Note: This step is important because every motherboard manufacturer uses a different BIOS in their motherboard. And in turn every BIOS will have different BEEP codes specified to it. Check Determining BIOS to determine the BIOS used in your computer.
5. Once you found out your computer BIOS and the BEEP codes, you can refer the BEEP code list given in BEEP code list and diagnose your problem.
For Example: If your computer produces “1 Long, 2 Short beeps” and your computer uses Award BIOS, then you can conclude that “Video adapter failure Bad video adapter ” in your computer.
