With the continuous development of the times, Computers are becoming more and more important in our lives. Whether for work, study or entertainment, computers play a vital role. However, sometimes we encounter some problems when using the computer, such as no sound after reinstalling the system.

The lack of sound after reinstalling the computer system may be caused by a variety of reasons. Here are some possible solutions:

You can check if there are any driver issues through Device Manager and try reinstalling or updating the audio driver. 2. Check the volume setting. Sometimes the computer's sound settings may be turned off or turned down, resulting in no sound being heard. You can adjust the volume through the sound settings or the volume icon on the taskbar. 3. Check whether the speakers or headphones are connected correctly. If you are using external speakers or headphones, there may be no sound output due to incorrect wiring. Make sure your speakers or headphones are properly connected to your computer's audio jack. 4. Check whether the audio device is working properly. You can check whether the audio devices are normal by plugging and unplugging them, and you can try connecting the audio devices to other computers to test. 5. Check the system sound settings. Sometimes the system sound settings may be changed, resulting in no sound output. You can open the sound options in the system control panel or settings to confirm whether the sound settings are correct.

Encountering no sound problem after reinstalling the system may affect your daily use, so it is very important to solve it in time. If you have tried the above methods and still cannot solve the problem, it is recommended that you contact a professional computer repairman for help.

3. Are there two systems installed on the computer?

I have installed both virtual machines and dual systems.

〈VMware virtual machine win7 system

Bootcamp assistant win10 system〉

Based on your usage scenario, dual systems are recommended.

The reasons are explained below:

Virtual machine

The advantage is that it is easy to switch between mac and win systems.

But the disadvantages are also obvious,

Disadvantage 1-Two systems consume the same set of hardware resources at the same time, which is bound to mean that the best performance of both systems cannot be fully exerted.

Disadvantage 2-The learning cost is relatively high, including installing software on the virtual machine, 3D hardware acceleration, and unplugging the hard drive. You have to learn almost every extra operation on a virtual machine.

You are studying in school, and you do not need to switch systems at the same time during the learning process. So there is really no need to install a virtual machine because of the convenience of system switching.

Install dual systems

(Never install win10, that automatic update is too disgusting and hurtful, win7 and 8 are both good choices)

Due to A time period corresponds to a certain system

First of all, the system being used will exert its maximum performance during this time period, and there will be no deviation when you use any software.

Secondly, the learning cost for novices is very low. Just learn to install the system and switch systems at startup. The rest of the operations are the same as on a win computer.

Of course win will consume more than 40G of your space, but compared to the loss of selling your computer, this space is really nothing, and it will not affect the normal operation of your MAC.

Now that you have bought a mac, don’t switch to a win computer. Otherwise you will regret it. What's more, there are experts who have pointed out the beauty of unix.

In addition

It is not recommended to use one Mac software to replace the behavior of another Win software. The usage scenarios are inconsistent, how to attend class, listen to lectures, and hand in homework. How to adjust the format? After the Mac is adjusted, what does it look like on the Win computer? These are all problems.

Extra

I once helped a 70-year-old teacher repair his iMac (a very old model, it seems to be a 2006 model). Since I have been using the win system, my mac has not been touched. Later, the win system broke down. I helped him press the ctrl key to switch back to the mac. It was no problem at all and the smoothness was very good. I have been using it for more than a year now and there is no problem at all. If I continue at this rate, I will still be able to use it for a few more years.

People who have been using win10 would not dare to say this to death.
