Black screen but music still goes on

Hi! I have issue with my ACER PC (Linux OS) when I leave him be for a while. I work on Word document while listening to a radio or a YouTube channel. Once I leave, I do not close anything. However, upon return, I am greeted with black screen but music still goes on. Shortkeys do not work and need to hard-boot it to make it work again. What might be the solution for this?
