How do I reformat the drive? (again I’m computer illiterate)
Stick the XP OS disk in and follow directions.
stick your XP cd in the drive and set the bios to boot off the drive.
Fair warning: you’re gonna lose everything you had on the disk but at least you’ll have a clean install.
Folks that suggest you use AV to clean it now mean well, but it’s always been best to just clobber the thing, reinstall all software, install AV, and install imaging. Build the image and the next time you goof, just rebuild from the image. It’ll be just like you left it.
