Is it possible to retrieve files lost after restoring my computer? I lost pictures & documents.?

There's no guarantee and if it's been written over it's gone. But there's always a chance to recover the files with file recovery software. I reccommend Recuva (pronounced "recover"), it is a freeware Windows utility to restore files that have been accidentally deleted from your computer. This includes files emptied from the Recycle bin as well as images and other files that have been deleted by user error from digital camera memory cards or MP3 players. It will even bring back files that have been deleted by bugs, crashes and viruses!

There are two kinds of people: those who have experienced data loss, and those who will. Remember the 3 rules of computing. 1) Back up 2) Back up 3) Back up.

If you have reinstalled Windows to restore your computer, the disk was reformatted and all data was lost.

Yes, data recovery software is usefull, but it must be installed before you have a crisis.
