Have you tried any of these steps?

Mac doesn't boot

Resolve startup issues and perform disk maintenance with Disk Utility and fsck

Troubleshooting: My computer won't turn on

A flashing question mark appears when you start your Mac​

Maybe the HDD has been damaged. If you can, boot from an external HDD with Mac OS X on to see, if that is the case.

The beep, is it a single one or a series of 3? The computer may be failing POST (Power On Self Test), and would seem to suggest an issue with the RAM. Consider re-seating or replacing the chips.
