Heya Lebron,
Just going with the fact that you heard clicking says to me your hard drive is failing. Next time you boot up, hit F8 over and over till you get the boot options. Then hit the option that says disable reboot on system failure. That will cause it to stay on the blue screen next time it fails during startup. Note then what the blue screen says.
From that model number, it looks like you have a Western Digital hard drive. I would go to their website and download their hard drive diagnostic tool and run it. It should be free and it will test the integrity of the hard drive.
See what happens from there
