recovery problem

i am trying to do a format on my pc to try to get it back to factory settings but the problems is when, i try to wipe the hard drive all i get is a personal recovery and it brings it all back to the point in which the wife did a personal recovey, i have tried a few times to do a format but it takes more memory and brings it all back ,i was wondering if a super recovery would do it but there are no discs with the pc its, all build in so am kinda scared to do it ,its just i want rid of this partition so that i can at anytime bring it back to factory settings am really needing some advice so any would be great
