Compaq Presario Driver probem

I have just bought a new laptop (Compaq Presario C 700) and I try to setup the drivers by mysefl. My OS is Window XP Professional and I download drivers from the HP and then I setup it but there are two driver that I cannot complete them:
1. Audio Device on High Definition Audio Bus.
2. SM Bus Controller

So, could you please help me?
