MacBook won't boot on Yosemite after force power off

Macbook suddenly froze while I was using Google Chrome so I waited for 15 minutes hoping it would un-freeze. After 15 minutes, I decided to force the power off by pressing and holding the Power button. When I tried to turn it on again, I heard the chime, but the screen remained white, and the hard drive started making clicking noises. Model identifier: MacBook6,1 OS X 10.10 Yosemite
