The sound of booting up and not entering the windows system is emitted by the motherboard.,I think it's mostly a problem with the speaker.。

Is the horn inside broken?

Summary. It will take a little time to type and sort out the answers, so please wait.

It will take a little time to type and sort out the answers, so please wait.

The solution is as follows: 1. First of all, confirm that the hardware is okay and sell the shed. 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 correct. 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. Under normal circumstances, after the sound card driver is installed, there will be a small speaker icon in the taskbar in the lower right corner. 4. 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, please click the "Options" menu - select "Properties" - select "Volume Control" and "Waveform" in the "Show the following volume control answer system", and then set them correctly.

In fact, many times, the reason why the computer does not work properly is a small fault, a soft fault, careful analysis, many mega times can easily solve the problem.

If it doesn't work to check the sound card driver,Then update the driver.,Or it's a virus.,It's best to have a system restore installed.,It should be possible to restore it.,I've been like this.,That's how it was solved.。

Clever trick to solve the problem that there is no sound on the computer.

There is no sound problem on the computer, such as no sound when the computer is turned on, and the small speaker in the taskbar is missing, which often makes the rookies at a loss and don't know what to do. In practice, everyone will encounter similar problems. I've come across it three times on my computer.

After repeated exploration, I finally found several solutions. Now I dedicate it for the reference of netizens.

First of all, the computer is silent, but sometimes the problem is more complicated, involving both hardware and software problems. Therefore, it is necessary to find out the cause first, see if the software or hardware is malfunctioning, and then prescribe the right medicine for the problem. We must not mess around for unknown reasons, because if we don't do it, the system will be paralyzed, and the trouble will be big.

1. Check whether the sound card, cable, speaker and other equipment are connected normally; Run anti-virus software for anti-virus;

2. Right-click "My Computer" -- Properties -- Hardware -- Device Manager, and open "Sound, ** and Game Controller" to see if there is any yellow in front of you? "If so, reinstall the driver for this device to solve the problem;

4. When there is no sound and no speaker, open the control panel--- Add and remove programs--- add and delete Windows components, put a check mark in front of "Accessories and Tools", click "Next", and then, shut down and restart, the system will prompt you to install new hardware, follow the prompts to install;

5. Uninstall the sound card driver, reinstall or upgrade the audio driver;

6. When the sound card driver is installed, the prompt "AC chip cannot be found" appears, it may be that the computer is poisoned, or the sound card driver has been deleted by mistake due to illegal operation, or there is an internal software conflict. The solution is to reinstall the system and drivers.

7. Simply ignore it, wait for a period of time after shutting down and then turn it back on, sometimes the sound problem will solve itself. You might as well give it a try.

This kind of problem is still a driving thing!

You reinstalled it, but it didn't install it correctly.

Then, uninstall the device with the exclamation mark, restart the computer;

Finally, install the reaudio driver.

Sound card driven! Or the horn is not in good contact!

See if mute is used.

Then install the sound card driver.

Steps to know the sound card model:

1.Select on the desktop"My computer"- Right-click - Menu selection appears"attributes"- Pop-up screen to quickly accompany the selection"Hardware"Let's argue - click"Device Manager"button - Select in the pop-up list"Sound, **, and game controllers"--From the menu, you can check the type and manufacturer of the sound card.

3.Check the information on the packing slip or configuration sheet that came with your purchase to find out the sound card model.

Then log in.

You delete the driver of the sound card and reinstall it to take a look.

I've also encountered this situation, at the beginning, it was poisoned, and there was nothing to do if I redid a system, you don't rush to run there, enter the dxdiag command, and see if the sound card inside is broken, and there is a situation that the sound card is blocked, how to do it, I don't know?
