Sound driver missing

The only driver I need left to install is my sound driver. But I cannot find out which driver I need. I bought this motherboard:

I am using the onboard sound card. But I'm not too good with soundcards, so I don't know what I need. Can someone help?

 

I also forgot to mention that I am on Spring Break, and I left the CD with all the drivers back at the dorms, so I don't have the disk with the needed drivers. :cry

 

Nevermind guys. I found the drivers I needed. Sorry for all the posts

 

u also forgot to mention what os ur using
