Display trouble- won't centre, black border- Lenovo c200?

Hello. I have a Lenovo 3000 C20 and there is a problem with my display. I cannot get it to centre, there is a thick black border on the left hand side and along the top. It affects the whole system, for example, I cannot see the clock. I have tried doing a system restore and for some reason it was unable to restore from any of the check points. I have tried adjusting the settings on display properties but that did not work either. I have also reinstalled the graphics card.

Please can you help me?? It is driving me crazy!
