How to solve the problem of three short and one long noise in the mainframe of the computer? Many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can gain something.

The host is always three short and one long, which is usually a memory error:

1. The memory is not plugged in, just re-insert it.

2. Memory damage, just replace it.

Common computer sound malfunctions:

"tick..." A continuous short tone:

In general, there is a problem with the power supply that is common in the host computer in ①. However, sometimes when the power output voltage is low, the host does not give an alarm, but the hard disk is lost, the reading performance of the optical drive is poor, and the computer often crashes. When these situations occur, it is best to check whether the output voltage of each channel is on the low side. When + 5V and + 12V are less than 10%, the above problems will occur from time to time.

Because of the voltage output of the power supply, ② often mistakenly thinks that there is a problem with the motherboard or hard disk, and wastes a lot of time. The reason for the low output voltage is caused by the loss of capacitance or leakage of the filter capacitor in the output part. when the DC component decreases, the high-frequency AC component in the power supply increases, which will interfere with the normal operation of the motherboard and cause system instability. Prone to panic or blue screen phenomenon. However, in this case, on some kind of motherboard of INTEL and gigabyte, if the system appears "tick …" Continuous short sound is not a power failure, but a memory fault alarm, which needs to be noted.

The sound of the ambulance, accompanied by the constant sound of turning on the phone:

① this situation is CPU overheated system alarm sound, mostly because of dust removal for the host, cleaning CPU radiator or because of the replacement of a new CPU fan, because the installation is not in place, CPU radiator and CPU contact is not firm, there is a certain space or sundries, resulting in the heat emitted by CPU can not be dispersed normally, a boot CPU as high as 80-90 ℃.

If the ② is a CPU below PIII, because the temperature test of CPU is collected by a temperature probe near CPU, there is a certain error between the displayed temperature value and the actual temperature value of CPU, which is about 10-20 ℃. While the temperature sensor of PIV's CPU is integrated in the CPU, the CPU temperature displayed by the system is more accurate. As long as the mainframe is powered on, the CPU temperature indicated by the system is about 50 ℃, which is normal.

"tick... tick..." Continuous long tone with intervals: this is the sound of memory alarm, which is generally caused by loose memory, poor contact between memory gold finger and memory slot, oxidation of memory gold finger, malfunction of a certain chip in memory, and so on.

Tick, tick

. "Doodle" has no movement after two long tones, and after a while you will hear the sound of "creaking" reading the floppy drive: if there is an image display, it will indicate that the system will boot from the floppy drive and is reading the floppy disk. If there is no floppy disk in the floppy drive, the system will prompt that no system cannot boot and the system hangs.

When pressing the three keys "CAPS LOCK" and "NUM LOCK" and "SCROLL LOCK" under the WIN system, the PC horn of the host computer has a similar tone of "tick": for example, the PV40ML of the three emperors, which is a prompt function of the motherboard, prompting the user to change the input state of the keyboard, not a fault. But because some people do not understand the false fate, they think that there is something wrong with the motherboard.

A short "tick" sound: in general, this is the system self-test passed, the system starts normally. However, when some motherboards pass the self-test, there is no such tone, and there is no sound. Also note that some motherboard self-test time may be longer, will wait five or six seconds to hear the "tick" sound, need a little patience.
