AMI BIOS is a BIOS manufactured by Megatrends in the United States. Many popular motherboard manufacturers have integrated AMI's BIOS into their systems.
Other motherboard manufacturers have created custom BIOS software based on the AMI BIOS system. The beep code emitted by the AMI BIOS based BIOS may be exactly the same as the real AMI BIOS beep code below, or it may be slightly different. Refer to your motherboard's manual for specific instructions.
Note: The AMI BIOS beep code is usually short, continuous and fast, usually as soon as the computer is powered on. The beep occurs because your computer can't boot far enough away to display anything on the screen, which means that some pretty standard troubleshooting isn't possible.
1 short beep
A short beep from the AMI-based BIOS means that the memory refresh timer is wrong.
If you can boot further, you can use the best free memory tester, but since you're having problems with your memory, you'll need to start by replacing the memory.
If replacing the memory doesn't work, you should try replacing the motherboard.
2 short beeps
Two short beeps indicate a parity error in the base memory. This issue affects the first 64KB block of memory in memory.
Like all memory issues, this is not something you can fix or fix on your own. Replacing the memory module that is causing the problem will almost always resolve the issue.
3 short beeps
Three short beeps indicate a basic memory read/write test error in the first 64KB memory block.
Replacing the memory can usually resolve this AMI tone code.
4 short beeps
Four short beeps mean that the motherboard timer is not working properly, but it can also mean that there is a problem with the memory module in the lowest (usually marked 0) slot.
Usually, a hardware failure of the expansion card or a problem with the motherboard itself can trigger this beep code.
Start by reseat the memory module and replace it if it doesn't work. Next, assuming that these practices fail, reseat any expansion cards and replace any expansion cards that appear to be the culprit.
The last option is to replace the motherboard.
5 short beeps
Five short beeps indicate a processor error. A damaged expansion card, CPU, or motherboard may prompt this AMI tone code.
First, reseat the CPU. If that doesn't work, try reseat any expansion card. However, the CPU will most likely need to be replaced.
6 short beeps
Six short beeps indicate an 8042 Gate A20 error.
This beep code is usually caused by a faulty expansion card or a motherboard that is no longer working.
If you hear 6 short beeps, you may also be dealing with some sort of keyboard glitch. When troubleshooting A20 errors, you may need to reseat or replace any expansion cards.
Finally, you may be dealing with a fault that is severe enough to require a motherboard replacement.
7 short beeps
Seven short beeps indicate a general anomaly error. This AMI beep code can be caused by an expansion card issue, a motherboard hardware issue, or a corrupted CPU.
Replacing any faulty hardware that is causing the problem is usually the way to fix this beep code.
8 short beeps
Eight short beeps indicate a memory error.
This beep code is usually caused by a faulty video card. Replacing a video card will usually clear up this issue, but verify that it is properly installed in the expansion slot before purchasing a replacement card. Sometimes this AMI beep code is just caused by a loose card.
9 short beeps
九声短促的蜂鸣声表示存在AMI BIOS ROM校验和错误。
Literally, this is an indication that there is a problem with the BIOS chip on the motherboard. However, since replacing the BIOS chip is sometimes impossible, this AMI BIOS issue is usually corrected by replacing the motherboard.
Before that, try to clear the CMOS. If you're lucky, this will solve the problem for free.
10 short beeps
Ten short beeps indicate a CMOS shutdown register read/write error. This beep code is usually caused by a hardware failure of the AMI BIOS chip.
Replacing the motherboard can usually fix the problem, although in rare cases it can be caused by a corrupted expansion card.
Before replacing something, clear the CMOS and reseat all expansion cards.
11 short beeps
11 short beeps indicate a failed cache memory test.
Some important faulty hardware is often the culprit of the AMI BIOS prompt code. Usually the motherboard.
1声长蜂鸣声+2声短蜂鸣声
One long beep and two short beeps usually indicate a malfunction in the memory that is part of the video card.
Replacing a video card is almost always a way out, but try removing it and reinstalling it first, in case the only problem is that it's a little loose.
1声长蜂鸣声+3声短蜂鸣声
If you hear one long beep followed by three short beeps, this is due to a glitch in the memory of your computer system that exceeds the 64 KB mark.
Compared to some of the previous tests, this one has little practicality, because the solution is the same, which is to replace the memory.
1声长蜂鸣声+8声短蜂鸣声
One long beep and eight short beeps indicate a failed video adapter test.
Try reseat the video card and make sure that any auxiliary power supplies it needs are connected to a power source.
If it doesn't work, you'll need to replace the video card.
Alternate beeps
Finally, if you hear alternating beeps during computer use, at startup, or at any time afterward, you're dealing with a voltage level issue or a processor fan running too low.
This is a clear indication that you should turn off your computer and check the CPU fan and, if possible, the CPU voltage settings in the BIOS/UEFI.
NOT USING AMI BIOS (AMIBIOS) IS STILL NOT SURE
