Make internet explorer my default browser again

What do you mean "died" and "got it up again"? Did you re-image it (wipe the drive and brought it back to factory defaults)? If you did, your favorites are gone, they are stored in your local hard-drive in the user profile directory which gets deleted if you format the drive to do a restore.

You can try using a file recovery program, Recuva is a good free one, run that and see if it will pick up anything. You are looking for a Favorites folder in the your use directory if it gives you any results.
