"Sooner or later you will need to know the manufacturer and exact model of your motherboard, especially if you do plan to upgrade your computer, since the upgrade capabilities of your computer are set by the motherboard model you have. You will need to know this information if you need to perform a BIOS upgrade or download your motherboard manual or drivers. A BIOS upgrade is needed to make your computer to recognize a new CPU, and the manual is necessary if you want to check how much RAM your computer is able to recognize, for example."
