Alternatively referred to as an Onboard speaker, the Internal Speaker/Motherboard Speaker is a very basic speaker found on the computer motherboard that is responsible for Start-Up Beeps, ERROR Beeping noises, and other Mono tones. This speaker is very basic and is not a speaker for playing songs, music, or other complex sounds generated in a game.
Generally, 2 types of BIOS are widely used in all Motherboards, i.e. AMIBIOS and AWARDBIOS.
AMIBIOS is a kind of BIOS manufactured by American Megatrends (AMI). Many popular motherboard manufacturers have integrated AMI’s AMIBOS into their systems.
Other motherboard manufacturers have created custom BIOS software based on the AMIBIOS system. The beep codes from AMIBIOS-based BIOS may be exactly the same as the true AMIBIOS beep codes below or they may vary slightly. You can always reference your motherboard’s manual if you think this might be an issue.
Note: AMIBIOS beep codes are short, sound in quick succession, and usually sound immediately after powering on the PC.
1 Beep
A single beep from an AMI based BIOS means there has been a memory refresh timer error. The solution is often to replace the RAM in the computer.
2 Beeps
Two beeps means there has been a parity error in base memory. This is an issue with the first 64KB block of memory in your RAM. The solution is usually to replace the memory.
3 Beeps
Three beeps means there has been a base memory read/write test error. Replacing the RAM usually solves this AMI beep code.
4 Beeps
Four beeps means that the motherboard timer is not working properly. A hardware failure with an expansion card or the motherboard itself could be the cause of this beep code.
5 Beeps
Five beeps means there has been a processor error. A damaged expansion card, the CPU, or the motherboard could be prompting this AMI beep code.
6 Beeps
Six beeps means that there has been an 8042 Gate A20 test error. This beep code is usually caused by an expansion card that has failed or the motherboard that is no longer working.
7 Beeps
Seven beeps indicates a general exception error. This AMI beep code could be caused by an expansion card problem, a motherboard hardware issue, or a damaged CPU. Replacing the faulty hardware usually fixes the cause of this beep code.
8 Beeps
Eight beeps means that there has been an error with the display memory. This beep code is usually caused by a faulty video card. Replacing the video card usually clears this up.

AwardBIOS is a kind of BIOS manufactured by Award, now owned by Phoenix Technologies. Many popular motherboard manufacturers use Award’s AwardBIOS in their systems.
Other motherboard manufacturers have created custom BIOS software based on the AwardBIOS system. The beep codes from an AwardBIOS-based BIOS may be the same as the original AwardBIOS beep codes (below) or they may vary a little. You can always reference your motherboard’s manual if you to be sure.
Note: AwardBIOS beep codes sound in quick succession and usually immediately after powering on the PC.
1 Short Beep
A single, short beep from an Award based BIOS is actually an “all systems clear” notification. In other words, this is a beep code you want to hear and that you’ve probably been hearing each time your computer comes on since the day you purchased it. No troubleshooting necessary!
1 Long Beep, 2 Short Beeps
One long beep followed by two short beeps indicates that there has been some kind of error with the video card. Replacing the video card is usually the most you’ll have to do to fix this one.
1 Long Beep, 3 Short Beeps
One long beep followed by three short beeps means that either the video card isn’t installed or the memory on the video card is bad. Reseating or replacing the video card will typically fix the cause of this Award beep code.
1 High Pitched Beep, 1 Low Pitched Beep (Repeating)
A repeating high pitched / low pitched beep pattern is an indication of some kind of CPU problem. The CPU could be overheating or malfunctioning in some other way.
1 High Pitched Beep (Repeating)
A single, repeating, high pitched beeping sound means that the CPU is overheating. You’ll need to figure out why the CPU is getting too hot before this Award beep code will go away.

Important: Turn your computer off immediately if you hear this beep code. The longer your CPU is running hot, the higher the chance that you’ll permanently damage this expensive part of your system.
