Cannot install drivers

Question

I have just formatted my computer and now I cannot install some of the onboard drivers. The drivers which cannot be installed are: sm bus controller,Pci device and ethernet drivers. I have tried to download and install the drivers from their website (asrock) but with no succes. When i try to install the onboard ethernet driver it shows a "cannot find proper NIC"-error. There are no errors when I run the other setups but the drivers are not installed. Anybody who have had the same problem or know what to do?

thank you
