I got a computer, and I want to delete everyting off it. Is there a way to do that like in one go so I don't have to do everything individually?

Thanks.

You can reboot the hard drive which means you need to install windows again. Put the windows disk into the disk drive and when it says something like "press f8 to run setup* find the boot option and change the primary boot devide to your CD Drive. Then restart the computer and follow the instructions to wipe your hard drive and reinstall windows.
