What to do if my computer suddenly goes silent, I don t know what s wrong

There is no sound, most likely the sound card is faulty (maybe the speaker, maybe the audio cable). 2. The failure of the sound card is often a soft fault. 3. Solution:

Right-click on "My Computer" Properties Hardware Device Manager Sound, ** & Game Controller Open (dot + sign) Right-click on the sound card Update Driver Follow the wizard (you should have a drive disc with a sound cassette on hand).Wizard: Step 1:

Select the automatic installation software Insert the drive disc into the optical drive Follow the wizard. If it is a hard fault, that is, a hardware problem with the sound card, you can open the case, plug in and unplug the sound card, and try it with an eraser gold finger.

In addition, if you remember the date of the failure, use the Windows System Restore function to restore the system to the date before the failure (click Start - All Programs - Accessories - System Tools - System Restore).

If there is no sound on the computer, you can analyze it by following the steps below:

First, first confirm that the hardware is fine. (You can remove the speaker and replace it with another computer to try).

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, the task is in the lower right corner.

There will be a small horn icon in the bar. )

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.

Fifth, if the driver cannot be installed, then eighty percent of the sound card is broken. Since most computers now have integrated sound cards, the problem comes down to a problem with the motherboard. There's no way to do it except send it for repair, unless you're majoring in this area.

There is no sound card driver installed, usually on your motherboard's installation disk.

No sound or no microphone is usually a problem with the sound card driver or software settings, audio settings, or software conflicts, and hardware problems.

First of all, determine whether it is a driver problem, and how to judge whether it is a driver problem is: if there is no small speaker in the lower right corner and the volume control cannot be turned on, this is generally because the driver is not installed well (if it is not an integrated sound card, please re-insert the sound card.)

Most of them are integrated, just reinstall the sound card driver, generally in your motherboard drive disk or you have a ** online), if you can turn on the volume control, it means that the driver is fine, check whether the software conflicts and settings problems and hardware problems.

There is no problem with the sound setting, and the volume control is generally checked to see if it is muted.

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.

I've had this problem before, and it's simple to solve.

First, check to see if the cord of your speaker or headphones has fallen out or plugged in the wrong way.

Secondly, change the headphones or speaker to check if it is a problem with the headphones or speakers.

If all of the above is a problem, then check if the small speaker in the bottom right corner of the screen is muted, and if so, cancel it.

If that doesn't work, double-click on the little horn and drag the sliders for the first two options to the top. If the mute option for the first two is selected, cancel them.

If none of these methods work, then is your system 2000? If so, pay attention to whether your driver is correct.

I think it's a matter of contact.

Here's how I got it: turn on the volume control thing first, and then see if you have mute, if not, you can see if there is any sound from the TV's speakers, and if there is sound, then there is no way.

Restart your computer and try it.

Or use the "Driver Genie" software to do it.

You must have cleared the sound card driver as garbage, right? Reinstall the sound card driver and you're OK? I've had this experience... Ha ha.
