Why is my computer making an ambulance like alarm sound when it turns on?

It may be that the memory module is loose.

First, first confirm that the hardware is fine. If the speaker is fine, the sound card is fine, and if you've tested it on other machines and it's really good, then you can read on.

2. Make sure all the cables are exactly right. Then power on the speaker and turn on the volume switch.

3. Install the driver of the sound card correctly, if it is an onboard sound card, it is best to install the driver provided on the driver disk of the motherboard.

In fact, the computer does not make a sound, and many times it is because the sound card is not driven correctly. In general, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. ）

Fourth, if you are sure that the driver is installed correctly, then take a look at the volume settings in the computer.

The specific method is to double-click the speaker icon in the taskbar, and check whether the volume is turned off to the minimum in the "Volume Control" and "Waveform" dialog box in the pop-up "Volume Control" and "Waveform".

If these two options are not available in the dialog box, click on the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show Volume Controls" and then set them correctly.

Note: Step 4 can only be set up after the driver for the sound card has been installed correctly.

First of all, look at the fan, the fan does not dissipate enough heat, which can easily lead to automatic shutdown;

In addition, make a sound,This situation should basically be a hardware problem,It is recommended that you find a professional after-sales maintenance test,If you test it yourself,You can open the main chassis,Like the initial build,One by one basic hardware for troubleshooting。

At first, only use the power supply, motherboard, and memory to see if it can be lit, and if it is running normally, add other hardware, such as hard disks and graphics cards. If even the lighting is not normal, replace it with a good hardware of the same model and then see the effect, confirm that it is a problem with a certain part and then replace it until all parts are running normally.

In the past, it was common for computers to make the sound you said on the hard drive, but it is not impossible for other components, such as power supply problems and unstable voltage, which can also cause the hard drive to stall. In short, it is still necessary to carefully check each component to achieve the best effect.

BIOS Alarm You have a hardware problem.

Disassemble the computer, try one by one, which one alarm, and then according to the manufacturer's manual, check the corresponding problems of the alarm.

Have you ever fallen, unplug the memory stick, erase the golden part with an eraser, and plug it back in. There is only one tick sound for detecting the hard disk through normal boot.

The alarm sound is tick-tick tick or tick-and-click, and it rings continuously.

The sound of the ambulance was accompanied by the sound of the start-up captain.

This situation is the system alarm sound of CPU overheating, mostly because of dust removal for the inside of the host, cleaning the CPU radiator or because of replacing a new CPU fan, because the installation is not in place, the CPU radiator and the CPU are not in good contact, there is a certain space or there are debris added in between, resulting in the heat emitted by the CPU can not be dissipated normally, and the CPU is as high as 80-90 as soon as it is turned on. If it is a CPU with a PIII or less, because the temperature test of Rubi CPU is collected by a temperature probe near the CPU, the temperature value displayed is subject to a certain error with the actual temperature value of the CPU, which is about 10-20 different. The temperature sensor of PIV's CPU is integrated inside the CPU, and the CPU temperature displayed by the system is more accurate than that of the CPU.

Generally, as soon as the host is turned on, the CPU temperature prompted by the system is about 50, which is normal.
