I had a similiar problem one time where when I booted up, my monitor was on the tv and the singer/tv screen was on my monitor. The only way I could fix it was cmpletely shut down, disconnect the tv and reboot - forcing windows to recognize my monitor as a monitor. Then reboot again with the tv connected (I may have had to resetup my display properties-I can't remember)
I've had a couple of similiar problems and I found that "restart"ing would not fix, but a complete shut down and reboot would.
You might give this a try, hope it helps.
I don't know why you would have lost files because of this though.
