If I select to format my c drive will this wipe out everything, If so how do I reinstall what it needs to start fresh, what IM trying to accomplish is to get rid of all the unnecessary files and programs that were once installed an now not needed to run the computer , there is a lot of garbage in there that's jamming up and slowing down my lap top, the biggest problem is MY CD ROM don't work because its drivers aren't working and IM not on line because I don't have the adapter cable for the Ethernet to usb. so what I do have to work with is a floppy drive and a Sony flash micro vault and my good PC that's it.
