Is your cpu a prebuilt one?(dell or some company)
A pre build one . most part of my cpu is asus brand sir..
personally i would reimstall my OS and deal with the prob. and the data will be saved in a folder called windows.old.
But if you dont want to do that i suggest you wait for a reply
PS- i have never used the CD that comes with prebuilt systems,So i dont know much about their content
an dmostly you best bet would be using system restore.
Genrally this is the procedure - go to system restore and select an option (date) to which your system will be restored(this works for any settings change inly and does not remove programs)
OR you could go into the win 7 setup AND THEN choose the repair option inside
