I hate to sound too stupid, but can Windows 2000 or Windows XP be installed on a pc that came with Windows 98.  I am suddenly finding that Windows 98 is practically obsolete for all the music jukeboxes and download services such as MusicMatch and iTunes.

Since I use my computer mainly for my business and have all my files, etc. on it, I need to keep it for business purposes.  However, if I can't upgrade to a newer version of windows I may have to get a new computer just for my "fun stuff" such as games and music.  I would hate to do that since I play in between working some days to let off stress, but if I could upgrade I would like to.

Thanks.
