Disconnect anything external and try it again, perhaps with Shift held down.
Hearing the chime repeatedly after a short while could be the Mac trying to boot, then reboot ... from a bad OS. Got another OS to boot from, maybe on DVD?
Hearing it beep in quicker succession is more like it's failing POST (bad RAM or something else internal).
