I had the same problem. Drive would not boot up correctly, i could reformat and reinstall snow leopard but when i would try to reboot, nothing. I bought a new hard drive and it didn't work either. After taking everything to the Apple Store, they said that lots of the macbook pros from 2009, the hard drive cable/ribbon were just going bad and they replaced the cable for free.
