Acer Spin 5 black screen and fan at full speed. What to do?

I have the following problem, my Acer Spin 5 laptop, which I bought this spring, is not working. The laptop screen is black and the ventilation is running at full speed. I don't know what to do because the laptop does not react to being switched on and off. I hope someone of you can help me. I would need it for school tomorrow.

That could be due to the processor. Well, I think they have to take it in for repairs. Or use the guarantee if the computer is still within the guarantee period.
