So I'm having a lot of driver conflicts, and I can't figure out which ones. Its been like this for a while so I figure that if I delete everything and install everything again this could help fix the problem. So how can I delete everything on my Hard drive except my OP which is Window 7.

(This was a self made PC not a store PC so I don't have one of those recovery disks)

Thank You
