RAM error; unable to verify stability of the ram chips. Your course of action next depends on the age of your machine. Follow Mac computers: About startup tones - Apple Support for more help.

You can run the Apple Hardware test (on your install disk #2) - run the extended test at least twice; also you can take out one of the RAM modules and test, then test the other one.

You can purchase new RAM - best place is one of the two most recommended vendors OWC (macsales.com) or Crucial.
