The laptop can t hear sound after reinstalling the system

I don't have a sound card driver.,Open "My Computer" "Properties" "Device Manager" to see if there is an unknown device with a question mark, if there is, it should be that there is no sound card driver, install the drive disk you brought when you bought the computer, and install the sound card driver on it, it should be able to be installed automatically As for the office disappeared, it was because your newly installed system did not come with office, and some files could not be opened, because after reinstalling the system, some programs and the registry were not associated with it, so it could not be opened. You'll need to reinstall these programs and Office

Office is gone, and that needs to be reinstalled! After the system is reinstalled, most of the software is unusable and needs to be reinstalled. There is no sound and it is possible that the driver is not installed properly, you can reinstall it from here:

My Computer Properties - Hardware - Device Manager --- Sound, ** and Game Controller - Right-click and select "Scan for hardware changes" or directly select "Update Driver" and follow the prompts, as this should be solved.

Are you sure the sound card driver is installed?

Office has to be reinstalled, because you don't have these software on your machine now, so you can't open some files.

Reinstall the system to install the sound card, graphics card, motherboard driver, are you sure you install the sound card driver, some system disks do not have office, like excel, word and some do not bring, you yourself**.

1 There is sound before installing the system, and there is no sound after installing the system, the biggest possibility is that you did not install the sound card driver when you installed the system, of course, we can't jump to conclusions before finding out the specific reason. We right-click on "My Computer", click on the management option, and then find the Device Manager to enter the corresponding operation interface.

3 If you see an exclamation mark instead of a question mark after opening the option, it means that your sound card has installed the driver, but the driver may be damaged or mismatched or incompatible with your sound card, at this time we need to uninstall the original driver, and then install the matching driver.

4 Some friends may have regained the system sound after the above operations, and they have not been happy for long, the problem has come, the sound disappeared after the computer restarts, and there is no question mark or exclamation mark after opening the device manager, and reinstalling the driver can not solve the problem, many novice friends may feel at a loss, in fact, there is a solution to this situation.

5 We also right-click on "My Computer", still click on the "Manage" option, but this time we don't look for the Device Manager option, but look for the "Services and Applications" option, and after finding it, we click on the "Services" option, and then click to enter the list of services in Windows.

6 And today our protagonist is the Windows Audio service, according to the description we can know that it is to manage the audio device based on the Windows program, turn it off all audio devices and sound effects will not work properly, so we have to confirm whether it is turned on, if it is not turned on Click to start, then the sound you dream of may appear.

7 Some friends may ask, I didn't turn off this service, why did it stop, in fact, the reason is very simple, we use the security guard to optimize the boot startup item is likely to prohibit it, so the service will be stopped, the system has no sound, we had better set the startup type to automatic when we turn on the service, so that it will load itself as we boot up.

8 Of course, in addition to the above reasons, turning the system to silent, sound card damage may cause our system to have no sound, of course, the probability of this happening is very small, but there is also a probability of happening, so listed here, if other methods can not solve your problem, you may wish to see if it is caused by them.

Precautions. Service is a problem that many friends tend to ignore when we confirm that the driver is not.
