computer help: HOw do I delete all files and programs form my Dell computer? - Help.com

if you are really worried, get a program that fills the entire hard drive with zeros and then format the had drive afterwards.

with a hammer

Microwave is my favorite.

But if you want to format (remove everything including the Operating System), well ummm that depends on what operating system you are using, XP, Vista?

Skimpily format ur drives if u like to completely washout ur computer

it depends on whether or not you want to completely wipe the hd or not!

Do you want just your files gone/deleted ? then just create a new administrator account login using that and delete your account and your profile folder from c:\documents and settings\(me)
