Also, it makes no sense that you can boot and run and not see the drives in say Explorer.

Hey I just built my first pc a couple days ago and everything seems to be working so far except my hard drive isn't showing up when I go to "my computer". My friend put windows 7 on it for me and he couldn't install all of the drivers because we didn't have internet at the time and place of the build. So I was just wondering where I can find the driver I need to install, to get my hard drive connected. Thanks.
