System restore

Please help I accidently restored my pc to the original state when it first came in the box, I've lost all my documents, files etc. Is there anyway I can restore it back?!? I haven't made any back-ups. It all started because I scanned a memory card then Norton insisted I restart my pc. After all these random files were on my desktop so I decided to restore before the restart but it seems to have restored everything brand new.

Look for and pick a new Restore point,,, look in your Restore for more ..dates before the one you have choosen and currently use.
