MacBook Pro will not boot - have replaced hard drive and problem persists

Macbook Pro Mid 2010

4gb ram, 2.4 GHz Intel core 2 duo

Originally when I received a folder with a flashing question mark upon startup, I assumed I had a failed hard drive. I went ahead and installed a new 500GB hard drive in my machine and installed OS X Snow Leopard. I upgraded to OS X Mavericks, and I had everything running properly. The next day, I went to startup and my Mac would not boot again. The dreaded folder and question mark were back.

I'm wondering what else could be causing this problem? Is it something I can diagnose and repair myself or will I be better off taking it into someone at this point?

Thank you!

You can try replacing the hard drive cable...

Have you tried resetting the PRAM and SMC?

Does the hard drive boot when connected externally?

I will try resetting those items and see if that helps at all. I might try getting a USB enclosure and see if I can boot externally. Hard drive cable could certainly be a possibility, I will keep that in mind! Thanks for the suggestions !
