You may have bad RAM: Mac computers: About startup tones - Apple Support.
As I recall, three chimes indicates a memory issue.

you mean my rams may be loose connected?
Or it went bad. Make a Genius Bar appointment and let them take a look at it. Start at http://getsupport.apple.com.
i have been using the same mac for more than 2 years and no ram issue and why now? and do u know the fix?
Take out the RAM modules and clean the contacts. Reinstall them and make certain they are well seated. If no change. make the genius bar appointment that has been suggested.
