[Q] S3 Mini with latest CM 11 suddenly won't boot up topic

Hi guys, I've been using this rom for a weeks now without any problems until this. I left my phone to charge overnight and turned the charger off when I woke up. I didn't touch my phone until after I got home from school and it's suddenly like this. The power button does nothing, I don't think the 3 buttons do anything. I'm stuck. I created an account just for this. I hope someone will be able to help! I also enabled Battery Doctor's cpu management when the screen is off if it changes anything. Thank You!
