New graduate and can not find a position...any advice??

Hi,
I recently moved to Columbus Ohio from Bethlehem Pennsylvania where I went to school. I had a position waiting for me after graduation but I had to move for personal reasons. Since March I have been applying through HR and sending out my resume...and I have had no call backs at all!!
If anyone has any advice please let me know
Thank you
Angela
