MacBook Pro won't turn on. Beeps every 5 seconds

I Have a MacBook Pro (2012), and recently updated to OSX Yosemite. While I was running a program called Reaper (which is a audio recording program similar to garage band), the macbook locked up. The only option was to shut it down. But now it won't turn back on, and beeps every 5 seconds. The power/hd light in front is in sync with the beeps.

MacBook Pro (13-inch Mid 2010), OS X Yosemite (10.10.3)

You may try to restart your computer in Safe mode by taking these steps:

- Click on the Apple sign() at the upper left corner of the Desktop, select 'Shut down' from a drop-down menu;

- Wait until your computer turns off, then press the Power button(⌽);

- Immediately after you hear the startup tone, press and hold the Shift(⇧) key. It should be held as soon as possible after the startup tone, but not before the tone;

- Release the Shift(⇧) key when you see a grey Apple sign() and the progress bar below;

This will force the system to perform several maintenance routines and load essential system software.

Once you've seen the Desktop, start a Disk Utility scan to detect and repair file system errors:

- Open Disk Utility application:

1. Click on Finder at the bottom of your Desktop;

2. Select Applications folder from Finder's left sidebar and then open Utilities folder (or press Command(⌘)-Shift(⇧)-U), double-click on Disk Utility icon;

- Choose your main hard drive from the left sidebar ('Macintosh HD', usually);

- Click on 'Verify Disc' at the bottom right corner, your Mac will perform a diagnostic test. Click on 'Repair Disk' if prompted to fix problems, or follow instructions given on the Disk Utility window;

- Once the routine finished, click on ""Verify Disc Permissions"", after it's done, click on 'Repair Disc Permissions';

- Wait until the process's finished and shut down your Mac, turn it back on in 30 seconds;

If this will not help try to

Reset SMC.
