You will need to format your harddrive but this will delete
EVERYTHING so make sure you have backed up everything you need.
I'm working a little blind now it's been a long time since I have done a win98 machine.
Download this from
bootdisk.com run it making sure you have a floppy in your drive, once you have done that just to test it reboot the machine with the floppy in (I can't test it as I don't have a floppy drive in my computer) once it has booted in to DOS check to see if your CD drive is working, put your win98 cd in the drive and type d: or it might be e: press return, type dir then return see if it lists the cd contents.
Hopefull that is all ok if it is come back and I will talk you through the rest
