+1 ^, Windows already told you what you need to do, you need to logon as an admin level account to make changes in msconfig, and also to install the drivers. If you did not setup your PC, ask whoever did for help with getting on an account that can make system changes. You can also try to logon the computer with an account called "Administrator", try no password or something like "password". Many OEM systems do not set an administrator account password by default.
