Save Data if possible.

Use Restore System; Restore Computer to Factory "New" Condition.. Sont Vaios have a Key Prompt which you hold down while booting and the Replacement Software already on a Sector of the Hard Drive. Check THe Manuel for this OR CALL SONY CUSTOMER SERVICE AND JUST GIVE THEM THE MODEL NUMBER AND ASK THEM WHICH BUTTON YOU PUSH ETC TO RESTORE THE COMPUTER TO "FACTORY CONDITION"
