Clicking noise from my Macbook Pro

I just purchased a 15" Macbook Pro a couple days ago. All seems to be working great except for one issue. When I move my laptop even slightly, I get a clicking noise from the right side of my laptop. I could even be shifting my body a little bit to get more comfortable while its on my computer is on my lap and it will be sensitive enough to make this noise.

This is my first Macbook, but not my first laptop and I've never had this issue before which leads me to believe that this is weird.

I suspect it could be the hard drive?

When I'm watching a video off my hard drive and I shift around a little bit, I'll get the clicking noise and the video will skip.

Thanks, any advice would be great!
