There is no alarm sound when the computer starts, and the startup is normal

If it starts normally, you should call the police (a short time), if you don't hear the alarm sound, there are three possibilities.

1. The buzzer is not installed, or the buzzer cable is not plugged into the motherboard.

Second, there is a problem with the hardware.

3. Turn off the buzzer in the BIOS, and some motherboards can be turned off, but it is recommended here that it is best to turn it on, because the buzzer is a basis for us to judge whether the computer is normal.

Normally, there will be no alarm sound, if you say that there is no sound because the spea** of the case is not connected to your motherboard, if there is no spea**, you can find a small speaker, which is the kind that says speak.

There is an alarm sound when the computer starts??? You mean there is no "ding" sound when the device is turned on.

Normal.

There is no alarm sound, the startup is normal, and what problems do you have to solve.

Please, what else do you want the computer to boot up properly?

What problems do you want to solve when you start normal?

1. First of all, we conduct a comprehensive check on the connection between the computer monitor and the host, and plug each connection back to see if there is a connection problem.

2. If the fault still exists, then we need to open the chassis to see if the chassis contains metals and other substances, causing a short circuit in the computer host circuit, and then we smell the computer to see if there is a burning smell, and see if there are damaged components around the motherboard and around the CPU.

3. After checking the whole chassis, there is no abnormality in the chassis, then we will dust the chassis.

4. If it can't be turned on, then use the minimum system method, unplug the data cable of the hard disk, floppy drive, and optical drive, and then check whether the computer can be turned on. Then connect the above devices to the computer one by one, when connecting a certain device, the fault will recur, indicating that the fault is caused by this device, and finally focus on checking this device.

5. If the fault still exists, it is likely to be the fault of the memory card, graphics card, CPU, motherboard, etc., at this time, we only need to plug and unplug these hardware, or replace it again, and try to find the cause one by one.

6. If the memory, graphics card, CPU and other devices are normal, then discharge the BIOS, use the isolation method, place the motherboard outside the chassis, connect the memory, graphics card, CPU, etc. for testing, if the computer can be displayed, then install the motherboard into the chassis for testing until the cause of the fault is found. If the fault persists, you need to return the motherboard to the manufacturer for repair.

7. When the computer is turned on and started, the system BIOS starts to POST (power-on self-test), and when a fatal error is detected in a device in the computer, it will control the speaker to send out a sound to report the error. Therefore, there may be a fault that the power is turned on without displaying an alarm sound. If the computer is turned on and there is no alarm sound, the fault can be checked according to the meaning of the BIOS alarm sound to check the faulty device to eliminate the fault.
