I have an old computer that I am wanting to reformat or cleanup for my kids. It will only be used for games. I have a good graphics card do I dont need any advice there. This is my problem. I use to have windows 98se on it, My neighbor who worked for Dell brought me a few years ago some type of disc that upgraded to XP. It say Reinstallation on it. Anyways I have my CD's from 98se but I dont have the code to re-enter when I reinstall it. So any help to do the following would be great. I want either A) remove XP and put back 98, since most of the games were bought for that OS. or just clean up/reformat what I have without wiping out the hard drive. I can buy more games if I need to I just want to get it done. The computer just has junk on it I dont want on there anymore. Note I have gone thru and did the add/remove of some programs but there has to be a better way.
