I was using my laptop last night, and this morning when I opened it, my keyboard and mouse were completely frozen. I wasn't sure what was wrong, so I restarted it and now the computer won't boot up. When I restart it, it goes to these black screens (seen below) and nothing works. It looks like a bluetooth track pad but I don't have one connected and never did . I can see the mouse cursor on the screen, but I'm unable to move it. My computer is a Macbook Pro and I purchased it in 2015. Thanks ahead of time for anyone who can help ! Also, not sure if it makes a difference but the only button that works is the power button.
