Check the LIB sub-folder under Delphi. There should be a bunch of .dcu files there, including System.dcu. If there are not, you'll need to reinstall Delphi or get them from another user. If the files are there, check to see that this lib folder is included in the Library Search Path in Delphi - Library tab in Tools|Environment Options.
