The general meaning of ringing is:1 short: the system starts normally, which we can hear every day, but also that the machine does not have any problems.2 Short: General error, please enter the CMOS Setup, reset the incorrect option.1 long 1 short: RAM or motherboard error, try for a memory, if still not, had to replace the motherboard.1 long 2 short: display or graphics card error.1 long 3 short: Keyboard controller error, check the motherboard.1 long 9 short: the motherboard Flash RAM or EPROM error, BIOS damage. Try block Flash RAM.Continuously beeps (long tone): The memory module is not inserted or damaged. Re-insert the memory, if not, only replace a memory.Keep ringing: power, the display is not connected with the display card. Check all the plugs.Repeat short beep: Power problem.No sound No display: Power problem.

AMI BIOS ringing sound of the general meaning is:

1. A short sound, memory refresh failed. Memory damage is more serious, I am afraid not have to replace the memory is not.2. Two short, memory parity error. You can enter the CMOS settings, parity Parity memory option turned off, that is set to Disabled. However, in general, the memory bar has parity and parity settings in the CMOS open, which is the stability of the computer system is good.3. Three short beeps, the system basic memory (the first 64Kb) check failed. Replace the memory bar.4. four short, the system clock error. Repair or replace the motherboard.5. Five short, CPU error. But not necessarily all of the CPU itself is wrong, it may be a CPU socket or other places where there is a problem, if the CPU on other motherboards normal, then certainly the error lies in the motherboard.6. Six short, keyboard controller error. If the keyboard is not plugged in, that easy to handle, plug on the line; if the keyboard is connected to a normal error, you may wish to try a good keyboard; otherwise the keyboard control chip or related parts of the problem.7. Seven short, system real mode error, can not switch to protected mode. This is also the fault of the motherboard.8. Eight short, memory read / write errors. The memory chip on the graphics card may be damaged. If the memory chip is pluggable, as long as the bad piece to find and replace on the line, otherwise the video card needs repair or replacement.9. Nine short, ROM BIOS test error. For the same type of good BIOS try, if that BIOS problem, you can use rewrite or even hot-swap method to try to recover.10. Ten short, register read / write errors. Only repair or replace the motherboard.11. 11 short, cache error.12. If you can not hear the beep ring can not see the screen display, first of all should check whether the power is connected, in the maintenance is often easy to overlook, not connected to the motherboard power to boot test. Followed by a look at what is less plugged in parts, such as CPU, memory and so on. Once again, unplug all the card in question, leaving only the graphics card to try. Finally, find the motherboard clear (clear) CMOS settings jumper, clear the CMOS settings, so that the BIOS back to the factory state. If the monitor or graphics card and the connection is no problem, CPU and memory is also no problem, after these steps, the computer still does not display or ring at boot time, it can only be a motherboard problem.

Through the sound of the buzzer can determine the working state of the motherboard

Use range: 

computer boot, we will hear the familiar sound "beep" a sound, the general said the computer can be used normally, the sound is from the "baby" issue.

Red line is positive, black line is negative (in fact, regardless of positive and negative, as long as the interface can be used in the Speaker)
