MacBook Freeze, then Question Mark Folder and now it Won't Turn On?

So I was working on my perfectly fine macbook pro when suddenly it froze. Nothing was working and the cursor wasn’t moving. I pressed the power button for 10 seconds but it refused to restart. So I closed the lid and opened it again and I was greeted by a black screen which eventually turned into a question mark folder and then it shut itself down. I tried to power it up again using the power button and it just won’t power up. No matter what I try. Magsafe shows it was yellow for charging initially since it was a little less than full and now it’s green but it still won’t power on. I even checked to see if the fan was working when I pressed the power button but it isn’t.

Any help is appreciated. I had important work documents I was working on when it died. I had them saved though.
