Could be the card.
When I bought my D3200 I picked up a PNY Pro-Elite 16GB class 10 card and at first everything was good, then the camera was having problems recording video and then still pics. Got home and tried a couple other brand cards (sandisk and Panasonic) and all worked fine, The card was bad. took it back and then the something happened twice with replacement cards.
So I say away from PNY now. Replaced it with a SanDisk 16GB Extreme Class 10 UHS-I and it works great.
