Hi. I bought a dell xps 13 today and used the cd provided to re-install windows 7. |Unfortunately this removed all my drivers. I read some of the threads and found out that i should install them again one by one, and in a certain order, but i don't know how i should do that considering my ultrabook can't connect to the internet, doesn't have a cd drive (i used an external one, which i now can't use because the usb drive doesn't work). Help is appreciated. 
Re-Installed Windows 7; no drivers.
