Need help making new build like new again

[d-rags]

Hey Guys listen I just finishing putting together my computer and it all works fine, however I messed up one of my registry files or something. In any case, I want to format my build to the way it would be before I installed anything in it. BTW, I dont have any of my disks besides Vista. I left my mobo disk and graphics disk in my dormitory. I am going to download the drivers and put them on my external. What steps do I have to follow in order to make this comp like new again?

Enter BIOS and change the boot order so the cd/ dvd drive is the first boot device .
Put the vista disc in the drive and reboot .
