Hi. I'm new here and I need help. We have an IBM computer. Because of some problems we were having my husband put windows millennium on the computer. Unfortunately, it made our problems worse. Nothing will work right and we can't uninstall because we can't find it. We want o delete all files and put windows 98 back on. We have done this in the past and were ablt to go to run and type in format c:. Now it won't let us do that. We are not really familiar with fdisk, but tried that and still no luck. Can anyone help? We could always just get a new hard drive if we need to. Thanks for any help.
