2. There is also a situation where there is a problem with the computer software.

If it's a software issue, there are 2 ways to fix it:

What should I do if my computer's hard drive fails?

If the hard disk failure is a hardware problem, it is best to change the hard disk and reinstall the system, the data in the previous hard disk should not be lost, and it can be copied to the newly bought computer hard disk.

There is no sound on the computer, such as no sound when the computer is turned on, and the small speaker in the taskbar is missing

First of all, the computer is silent and seems simple, but in fact, sometimes the problem is more complicated, involving both the hardware aspect.

The problem, in turn, relates to the software side. There are also sound cards that do not sound due to sudden crashes and small speakers.

Disappearance is also common. Therefore, it is important to find out the cause first, see if it is a software failure or a hardware failure, and then prescribe the right medicine for the problem.

1. Check whether the sound card, cable, speaker and other devices are connected normally. If you have a virus, you should run antivirus software for full antivirus.

2. Open the control panel--- Add new hardware--- Next, after the search is completed, click "No, I haven't added this hardware", click Next.

Generally, when dealing with computer failures, we first deal with software and then hardware. If there is no sound from your computer, please try the following solutions, which can be solved.

Method 1: Check the sound control icon.

If there is no sound on your computer, check whether there is a sound control icon in the taskbar at the bottom right foot of your computer's desktop.

If there is this icon, it means that there is no problem with the sound card installed on the computer, and then click the sound control icon with the left mouse button, the sound volume adjustment switch control window will appear, check whether the volume is adjusted to the lowest, whether the mute is checked, and many novice friends have been helped to deal with the computer no sound in the past, many of them have either turned the sound to the lowest, or checked the mute, resulting in no sound on the computer, which is a low-level mistake that novice friends often make.

If you can't find the volume control icon on the computer desktop, it may be a driver problem, and the driver problem will know how to decide if you look at the following, and some are not displayed, so the way to make it appear is as follows:

If there is no "Speaker" on the right side of the taskbar, go to Start --- Settings - "Control Panel--Sound and Audio Devices" command to open the "Sound and Audio Device Properties" dialog box. After typing, click to make sure that there will be a sound icon in the taskbar at the bottom right foot of the desktop, and then check it, whether the volume is adjusted well and whether it is muted, and the computer generally has sound after resting.

You can also click the Sound tab in this dialog box, then click one of the program events in the Program Events bar (if the program errors), select a sound type, and see if the Preview button on the right is black. If it is black, the sound card is normal, and the fault may be due to the system volume being too low, or mute, or the speaker is malfunctioning.

Hello friends:

There is no sound from time to time, which is generally caused by poor contact with the output socket of the headphone or subwoofer, it is recommended to plug the jack or plug it in tightly.

Hope it helps you and I wish you happiness

Maybe you have ordered mute by mistake, maybe you have used the computer itself for a long time, and the line contact is poor, there are many reasons, first rule out the setting problem, if not, go to the computer city to repair. Thank you!

First of all, install the motherboard's driver. Then install the driver of the sound card. The reason is mainly due to software conflicts. It has nothing to do with anything else.

The second step is special instructions:If it shows no sound card driver or multi** management driver update,You can uninstall the original driver first'Uninstall it in my computer properties-hardware-device manager,Or you can also do it in the driver wizard,Then try there will be a driver update If it doesn't work,It's hardware reasons,Or external speaker equipment problems can only be repaired。

Check to see if the connector in the back is broken! Or poor contact.

Reinstall the sound card under the driver!
