Question: My mother in law has given me her old computer and I wanted to know if there is a way to completely wipe the computer clean and restart it as if it were new?
Answer: To wipe the computer clean and start over you need the Operating System install CD. Place that in the approppriate drive and boot from there. The install process should ask if you want to reformat the hard drive before installing, simply reply YES and the drive will be wiped clean. Finish installing the operating system to get the computer working again with nothing on it except for the operating system. You can then install whatever application programs you require.
