how to install mainboard driver?

Well below are the steps that I want you to just follow and install the required drivers on the system.

First of all I want you to Right click on "my computer"
And then select the properties option
And then go on selecting e "device manager" This will display a list of the devices that are on your computer.
Now you just have to Right click on the device and click”properties".
Select the driver that you want and then update it from there itself
There you will also be asked to browse for the new driver
