Excel charts don't display

I uninstalled Excel and re-installed it from the original Microsoft disk, no help. Still won't display charts. I then took some spreadsheets to my other computer and that machine displayed charts pefectly. So, something has happened to the Excel setup that prevents it from displaying charts. Do you have any ideas where else I could go for help. Some of the online help sites are very expensive. I don't mind paying a reasonable price for help, but $59 for a "possible" answer to ONE question seems steep to me.
