WoW Driver help.

I recently had some computer trouble and had to reinstall windows along with WoW and everything else I use. To get everything to work properly, I've had to download a few drivers and programs to make things work. To get to the point, I need to know what all is needed to run World of Warcraft. It always worked fine on my computer before. I just don't know what all I had that was making it work. Thank you for your time.

Games usually depend on the latest video and sound card drivers. You'll also need DirectX 9.0c and you can update it HERE (http://www.microsoft.com/downloads/details.aspx?FamilyID=2da43d38-db71-4c1b-bc6a-9b6652cd92a3&DisplayLang=en).
