|"I want to restore my laptop to factory settings"|
From what I could find, Ctrl+F11 is what you need, but you have to press the keys at the correct time. You also need to have the recovery partition. If you deleted it, you can't do the restore. I assume you never created the recovery disks?
"I am now downloading a driver repair kit from a site"
Driver programs are usually scams, you're most likely downloading an infection. Drivers should be downloaded from the Dell website.
