Meanings of BIOS alarm sound on several mainboard

Meanings of BIOS alarm sound on several mainboard

During computer maintenance, we often encounter BIOS error prompts during boot. If we are familiar with the reasons for these sounds, it is very convenient for us to eliminate computer faults, able to solve the problem in the shortest time.

1. Continuous short speech

Generally, the power supply of the host is faulty. However, sometimes when the power supply output voltage is low, the host does not trigger an alarm, but the hard disk may be lost, the drive reading performance is poor, and often crashes. When these problems occur, it is best to check whether the output of each voltage is low. When + 5 V and + 12 V are lower than 10%, the above problems may occur occasionally. Because the power supply has a voltage output, it is often a waste of time to mistakenly think of the motherboard or hard disk problems. The reason for low output voltage is that the filtering capacity of the output part is lost or liquid leakage. When the DC composition is reduced, the high-frequency ac composition in the power supply increases, which will interfere with the normal operation of the motherboard, the system is unstable and prone to crashes or blue screens.
However, if the system reports a transient sound on Intel and Gigabyte boards, it is not a power fault, but a memory fault alarm.

2. The sound of an ambulance saying "oh" is not stopping as the power-on grows.

In this case, the system generates an alarm when the CPU is overheated. Most of the alarms are caused by dust removal inside the host, cleaning the CPU radiator, or replacing the new CPU fan. Because the installation is not in place, the CPU radiator is not in close contact with the CPU, there is a certain amount of space or additional debris in the process, resulting in the CPU generated by the heat cannot be normally dispersed, the CPU on the machine is as high as 80-90 ℃. If it is a CPU below piII, because the CPU temperature test is collected using a temperature probe near the CPU, the displayed temperature value has a certain error with the actual CPU temperature value, the difference is about 10-20 ℃. While the piv cpu temperature sensor is integrated into the CPU, the CPU temperature displayed by the system is relatively accurate. Generally, as long as the host is started, the system prompts that the CPU temperature is around 50 ℃, which is normal.

3. The "audio..." has a continuous interval.

This is the memory alarm sound. It is generally caused by loose memory, poor contact between the memory's golden finger and the memory slot, oxidation of the memory's golden finger, and failure of a memory chip.

4. "Two consecutive tweets"

This is a video card alarm. Generally, the video card is loose, the video card is damaged, or the power supply of the video card on the motherboard is faulty.

5. There was no sound after the two long voices of "Doodle". Later, I will hear the sound of reading the soft drive.

If an image is displayed, the system is prompted to start from the soft drive and the disk is being read. If there is no floppy disk in the drive, the system will prompt that the system cannot be started and the system is suspended.

6. When you press the "Caps Lock" and "Num Lock" keys and "scroll lock" keys in the win system, the host's PC speakers have a "unlock" similar key tone.

For example, the pv40ml of Sandi prompts the user to change the input status of the keyboard, not a fault. However, some people do not understand the reason, and they think that the motherboard is faulty.

7. A short promotion of "RENEWAL"

Generally, this is a prompt message that the system starts normally after the system passes self-check. However, when some boards pass self-check, there is no such sound and no sound. Note that some motherboard self-check may take a long time. It may take five or six seconds to hear the "quit" message.
