Q: I need help. Mackbook Pro startup stuck.

My Macbook Pro is not starting up the system after I press the on/off button. Sometimes it loads and then I get instantly the gray screen and stuck, sometimes he makes reboot all alone. I don't know what to do? I changed HDD drive cause maybe broken some bad sectors. Nothing. I remove the memory one by one and start him separate. Nothing. Same problem. Maybe is from the operating system. Anybody have some suggestions? My system is purchased in 2012 December.

MacBook Pro, OS X Mountain Lion (10.8.5)
