If you want to do a clean format, then you need the OS's boot disk. You go into DOS and type FDISK. You need to delete all current partitions and then create a new one (or multiple ones). Then, when you are sure you want to format, you type ---> format c: and <enter>. Once the formatting is done, reboot the system with the boot disc, or the bootable CD-ROM, and set it up, its that easy. If you are installing Win 9x then make sure you use the Boot disk and select "start with CD-Rom support. Then you go into the d: or whatever your default cd-rom drive is and type "setup" and <enter>. Any more questions let me know.
