What should I do if the computer host makes three short and one long beeps?
The host always makes three short and one long beeps, which is usually a memory error:
1. The memory is not plugged in tightly, just plug it in again.
2. The memory is damaged, just replace it.
Common computer sound problems:
"Beep..." Continuous short sounds:
① Generally, there is a problem with the power supply of the host computer. However, sometimes when the power output voltage is low, the host does not alarm, but the hard drive may be lost, the optical drive's disk reading performance is poor, and it often crashes. When these situations occur, it is best to check whether the output voltage of each channel is low. When 5V and 12V are lower than 10%, the above problems will occur from time to time.
②Because the power supply has voltage output, we often mistakenly think that there is a problem with the motherboard or the hard disk, which wastes a lot of time. The reason for the low output voltage is the loss of capacity 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, causing system instability and prone to malfunctions. crash or blue screen phenomenon. However, in this case, on certain motherboards from INTEL and Gigabyte, if the system makes a continuous short beep of "Beep, beep...", it is not a power failure, but a memory failure alarm. This needs to be noted.
The ambulance sound of "oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo [[sic] the sound of an ambulance, accompanied by a long beeping sound when the computer is turned on:
① This situation is the system alarm sound of the CPU overheating, mostly due to the internal problem of the host. Dust, clean the CPU radiator or replace the CPU fan with a new one. Because the installation is not in place, the CPU radiator is not in firm contact with the CPU, there is a certain space or there are debris in between, causing the heat generated by the CPU to not be dissipated normally. , the CPU is as high as 80-90℃ as soon as it is turned on.
② If it is a CPU below PIII, because the CPU temperature test is collected using a temperature probe close to the CPU, there is a certain error between the displayed temperature value and the actual temperature value of the CPU, about 10- 20℃ difference. The PIV CPU temperature sensor is integrated inside the CPU, so the CPU temperature displayed by the system is more accurate. Generally, as soon as the host is turned on, the CPU temperature prompted by the system is around 50°C, which is normal.
The continuous long sound of "beep...beep...": This is the sound of a memory alarm. Generally, the memory is loose, the gold finger of the memory is in poor contact with the memory slot, the gold finger of the memory is oxidized, and the memory is damaged. One of the chips is faulty, etc.
"Beep..., beep" continuous beeping of one long and two short: graphics card alarm, usually the graphics card is loose, the graphics card is damaged, or the graphics card power supply part of the motherboard is faulty.
. There is no movement after two long beeps. After a while, you will hear the sound of reading the floppy drive: if there is an image displayed, it will prompt that the system will start 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 the system cannot start without it and the system will hang.
When pressing the three keys "CAPS LOCK", "NUM LOCK" and "SCROLL LOCK" under the WIN system, the PC speaker of the host computer will have a "beep"-like key tone: for example, Santi's PV40ML, This situation is a prompt function of the motherboard, prompting the user to change the input status of the keyboard, and is not a fault. However, because some people do not understand the reason, they think that there is a problem with the motherboard.
A short "beep" sound: Generally, this is the prompt sound that the system has passed the self-test and the system has started normally. However, when some motherboards pass the self-test, there is no such prompt sound and no sound at all. Also note that some motherboards may take a long time to self-test, and you will hear a "beep" after five or six seconds, so you need to be patient.
