This post will be helpful to find the suitable driver software like sound driver, video driver, chip set driver and all motherboard related softwares.      In your computer just open the comment prompt(Window key + R => cmd=> enter) and type the following command.      wmic baseboard get product,Manufacturer,version,serialnumber Step 1: Click on Start => Run Step 2: Type cmd and press OK.
