Disk utility can't find HDD

Hello,

I was playing music on my macbook 13" early 2011 and all of a sudden it stopped playing. After I logged in to my account on my mac the screen froze so I decided to do a reboot. After I tried to restart all I got as a folder with a question mark in it. I did my research and did many attempts on fixing it but disk utility just couln't find my macintosh HD. After reading lots about this problem on the web I installed a new (empty) HDD but still disk utitlity wasn't able to find it so I could not install OSX.

Can anybody help me, is it the HDD or something else and how can I solve this problem?

Thanks in advance!
