you need to install the motherboard drivers from the motherboard manufacturers site. as well as the gfx, sound and Ethernet.
you will find the gfx drivers at either nvidia or amd sites.
the sound and Ethernet should be in the same place as the motherboard drivers. unless you have a dedicated sound card.
if you have a lappy then there may not be any drivers for that lappy and that o.s as some manufacturers deliberately withhold then forcing you to buy a new laptop to upgrade the o.s.
