Not sure what you mean by "restore my computer". But you should understand that BOTH forms of Format will wipe out ALL of your data. (Well, technically not exactly that, but a Full Format may, and a Quick Format makes it extremely difficult to recover files so that you need file recovery software and a lot of time and patience to get your stuff back.) That means also the Operating System you have installed, so now you'd have to re-install. If you were going to wipe your drive clean and do a fresh Install anyway, just start from there!
