Start with that ^^ power is a bitch. and make sure the cable you use ( 
between power supply and pi ) is thick enough. It's amazing how much a 
good cable counts. I had an issue once, the power supply was juicy 
enough but the cable was thin and a bit too long. The voltage drop made 
the whole system unstable. Problem solved by replacing the cable that 
came with the power supply with a thicker one.
