Dell notebook 14 3420, no sound, I pressed a lot of drivers and it didn t work, why?

Hello, it is recommended that you must install the original Windows operating system, and do not use the ghost version of the operating system, because this kind of operating system is mostly a thin system, and the stability and compatibility are very poor. And be careful not to use the driver management software to find the public driver, but should use the factory-built operating system CD or go to the official website of Dell ** corresponding hardware drivers to install, so that the stability of your operating system is very high.

At the same time, because the current computer configuration is relatively high and the memory is relatively large, so chip manufacturers are also focusing on the development of drivers under the 64-bit operating system, it is recommended that you install the 64-bit operating system, otherwise the 32-bit operating system may not be able to use the driver after the installation of some hardware can not use the driver to drive normally.

In addition, you are reminded to use as little domestic optimization software as possible, and carry out the so-called "optimization" or "garbage cleaning", which can easily disable the boot operation of the driver or directly delete the driver by mistake, resulting in problems in the operation of the machine.
