AMD seem to have recently moved to an even more confusing site, (sites.amd.com) which does not make clear what to download and install if you do NOT have integrated graphics, nor which motherboard chipset they support.
What/where to download latest drivers for 790FX, and also 890FX?
More aboutwhere chipset drivers hidden
What motherboard make and model do you have? You will need to hit the manufacturers web site rather than amd.com...
Gigabyte; I know their download site, but the drivers there are often not up to date.
