Hiya Tammy
You need to install all drivers for your version of that motherboard
does the board have more letters after it "K8N ***"?
More letters or number should be present, you need these to clarify your exact model so you can search on the Asus website just to make sure.
You need to install All system drivers which will be available in several different packages to download
Here is a link for the model you posted
