CPU system restore issue

I restored my computer because it would no longer "notice" my printer out of no where. I know I am supposed to back up before restoring, but forgot to. Long story short, my finance's important files were on the computer and he was ticked (to say the least). I prayed over and over that they would just come back long enough for me to back them up.. :) silly, I know.. that would be merely impossible from what I understand. Funny thing (honest story) THEY DID COME BACK.. I backed them up.. and quite strangely, now everytime we restart our computer (and sometimes it restarts itself) it changes back and forth from the "before restore" to the "after restore" points on its own. We obviously want it to STAY at the original point so we don't have to download our stuff everytime it changes back. This is pretty much a weekly thing. How can I do this? Please help before he gets even more mad!! Thank you so much! By the way, I am an acquiring PC troubleshooter.. haha.. for real though.. I really want to learn. Please, please, please help!
