What about the "drip" sound on the computer?

Computer boot generally normal is a clear ' drip ' sound, if we find that the sound is not right, in most cases we can through the different sound, to judge the hardware areas of the computer problems.

For example, the power-on computer has been dripping, drip ring, the failure may be bad memory contact or damage, and so on, below for the detailed introduction of the computer may appear sound and the failure. The sound that the computer turns on appears that is the sound prompt that is issued when the BIOS self-test detects the fault.

　　BIOS self Test bell meaning

　　First, award bios self-test Bell meaning:

1 short: The system starts normally. Congratulations, there's nothing wrong with your machine.

2 Short: General error, please 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.

Keep ringing (long sound): the memory strips are not plugged in or damaged. Reseat the memory bar, if still not, only replace one memory.

Keep ringing: power supply, monitor does not connect with the display card. Check all the plugs.

Repeat short ring: power supply problem.

No sound is displayed: There is a problem with the power supply.

　　Second, the AMI bios self-test Bell meaning:

1 Short: Memory refresh failed. Replace the memory strips.

2 short: Memory ECC more error. The option to disabled memory about ECC checksums in CMOS setup can be resolved, but the most fundamental solution is to replace a single memory.

3 Short: System basic Memory (1th 64kB) check failed. Swap memory.

4 Short: System clock error.

5 Short: Central processing unit (CPU) error.

6 Short: Keyboard controller error.

7 short: System Real mode error, can not switch to protection mode.

8 Short: Memory error displayed. There is a problem with memory, try replacing the video card.

9 Short: ROM BIOS check and error.

1 Long 3 short: Memory error. Memory is damaged and can be replaced.

1 Long 8 short: Display test error. The monitor data cable is not plugged in or the display card is not in a good cell.

　　Three, Phoenix bios self-test Bell meaning:

4 Short 2 short 3 short A20 gate Error

4 Short 3 short 1 short Memory error

4 Short 3 short 4 short clock error

4 Short 4 Short 2 short parallel port error

In the maintenance of the computer, we will often encounter the boot, the BIOS error prompts, if we are familiar with the reasons for these voices, then we eliminate the computer failure is very convenient, can in the shortest possible time to solve the problem.

1, "tick beep ..." continuous short sound

Typically, there is a problem with the power supply for the host. However, sometimes the power output voltage is low, the host does not alarm, but there will be a hard drive loss, CD-ROM drive performance is poor, often panic. When these conditions occur, it is best to check the output of each circuit voltage, whether low, when +5v and +12v below 10%, will be irregular occurrence of the above problems. Because the power supply has voltage output, often mistakenly think the motherboard problem or hard disk problem, and waste a lot of time. The output voltage is low due to the output of the filter capacitor loss or leakage of liquid caused by the lower DC components, the power supply of high-frequency communication components, will interfere with the normal work of the motherboard, resulting in system instability, prone to panic or blue screen phenomenon.

However, in the case of Intel and Gigabyte motherboards, if the system appears "beep ..." continuous short sound, is not a power failure, but a memory failure alarm, this need attention.

2. "Woo-woo," The sound of ambulances, with the boot long rang non-stop

This situation is the CPU overheating system alarm sound, mostly because of the internal dust for the host, cleaning the CPU heatsink or because of the replacement of the new CPU fan, because the installation is not in place, the CPU heat sink and CPU contact is not in prison, there is a certain amount of space or in addition to the debris, resulting in the CPU out of the normal heat, One boot CPU is up to 80-90 ℃. If it is PIII the following CPU, because the CPU temperature test is near the CPU near the temperature probe to collect, the display temperature and the actual temperature of the CPU has a certain error, about 10-20 ℃ difference. The PIV CPU temperature sensor is integrated in the CPU, when the system shows the CPU temperature is more accurate. General host as soon as a boot, the system prompts the CPU temperature is about 50 ℃, this is normal.

3. "Tick ..." Beep ... "with a continuous interval of long sound.

This is the voice of memory alarm, is generally loose memory, the memory of the gold fingers and memory slot bad contact, memory of the gold finger oxidation, memory of a chip failure and other reasons.

4. "Beep ..., beep" a long two short continuous tweets

This is the video card alarm, is generally loose graphics card, video card damage, or the motherboard's graphics power supply part of the fault.

5. "Dudu" two long sound after no movement, after a while will hear "creak" read the sound of floppy drive.

If an image display prompts the system to boot from the floppy drive, the floppy disk is being read. If you do not have a floppy disk in the floppy drive, you are prompted that no system will fail to boot and the system hangs.

6. When the three keys of "Caps lock" and "Num lock" and "Scroll lock" are pressed under the win system, the PC Horn of the host has a "beep" similar to the key tone.

For example Sandi's pv40ml, this situation is the motherboard's one kind of prompt function, prompts the user to change the keyboard input state, is not the fault. But because some people do not understand the edge of the pseudo, it is considered the motherboard has problems.

7. The short "beep" of a sound

In general, this is the system self-test passed, the system normally starts the beep. However, some of the motherboard self-test passed, there is no such beep tone, there is no sound. Also note that some of the motherboard self-test time may be longer, will wait five or six seconds before you will hear "beep" a sound, need a little patience.
