My hard drive is full of junk, too many downloads have corrupted my dll libraries and my computer is just running way to slow for a pentuim 200. therefore I want to format my hard drive and start over. I have already backed up all of the stuff I want to keep onto a zip drive, I'm just not sure what to do next. 'Format c:' - is it that easy? I want to be able to start it back up again and install things (like Win98) from a CD-rom. Has anyone done this? Any help would be much appreciated.
