Sometimes, our computer does not start properly, and it emits a different beep, which means that the computer is faulty and needs to be ruled out. Beep is the computer BIOS preselection design good beep, we can according to the following content to determine exactly where the problem.

The current common BIOS has three kinds of award, Ami and Poenix, of which Poenix has been acquired by award, but it is common in many old brand machines, so it is listed here together. In addition to the three BIOS listed above, a very small number of computers use a special BIOS, which is no longer listed because there is no uniform standard. The general meaning of the

Award BIOS ring is:

1 Short: The system starts normally. This is what we hear every day, and it shows that there are no problems with the machine.

2 short: General error, go to CMOS setup and reset the incorrect option.

1 long 1 short: RAM or motherboard error. Try another memory, if not, have to replace the motherboard.

1 Long 2 short: monitor or display card error.

1 Long 3 short: Keyboard controller error. Check the motherboard.

1 Long 9 short: motherboard Flash RAM or EPROM error, bios damage. Try the flash RAM for another piece.

keeps ringing (long sound): The memory strip is not plugged in or damaged. Reseat the memory bar, if still not, only replace one memory. The

keeps ringing: the power supply, the monitor is not connected to the display card. Check all the plugs.

Repeat the short sound: power problem.

No sound is displayed: power problem.

Summer to dust the computer, to protect the cooling, reduce the occurrence of inexplicable failure. The general meaning of the

AMI BIOS ring is:

1. A short sound, memory refresh failed. Memory corruption is more serious, I am afraid it is necessary to replace the memory.

2. Two short sound, memory parity error. You can enter the CMOS settings and turn off the memory parity parity option, which is set to disabled. In general, however, the memory stripe has parity and turns on parity in the CMOS settings, which is good for the stability of the microcomputer system.

3. Three short sounds, System basic memory (1th 64Kb) check failed. Replace the memory bar.

4. Four short sound, system clock error. Repair or replace the motherboard.

5. Five short sound, CPU error. But not necessarily the CPU itself is wrong, it may be a CPU socket or some other problem, if this CPU in itsIt is normal on the motherboard, the error is definitely the motherboard.

6. Six short sound, keyboard controller error. If the keyboard is not plugged in, that good to do, plug on the line; If the keyboard connection is normal but there are error prompts, you may wish to change a good keyboard to try; otherwise, there is a problem with the keyboard control chip or related parts.

7. Seven short sound, system real mode error, cannot switch to protected mode. This also belongs to the motherboard's fault.

8. Eight short sound, memory read/write error. The memory chip on the video card may be damaged. If the storage slice is pluggable, just find the bad slice and replace it, otherwise the graphics card needs to be repaired or replaced.

9. Nine short sound, ROM BIOS check error. Swap the same type of good BIOS test, if you prove that the BIOS is problematic, you can use the rewrite or even hot plug method to try to recover.

10.10 Short sound, register read/write error. You can only repair or replace the motherboard.

11.11 Short sound, cache error.

12. If you do not hear the beep ring to see the screen, you should first check the power supply is good, in the overhaul is often easy to neglect, not connected to the motherboard power on the boot test. The second is to see if there are fewer components, such as CPU, memory, and so on. Once again, unplug all the cards that are in doubt, and leave only the display cards to try. Finally locate the jumper on the motherboard to clear the CMOS setting, clear the CMOS settings, and let the BIOS return to the factory state. If the monitor or display card and wiring are not a problem, the CPU and memory is not a problem, after these steps, the computer on the boot or does not show or ring ring, it can only be the problem of the motherboard.
