Seagate Barracuda 3TB won't power up

I had purchased this as a portable external hard drive. It's a Seagate Expansion 3TB Desktop External Hard Drive and was purchased back in late 2014. I went to use it today and it won't power up. I have tried to figure this out but I am a tech dummy. There are very important files I need on this. Is there a way to recover the data? An adapter to buy if I get to the card? A different way to recover that I can do myself?
