Laptop is lagging and making strange noises?

I have a problem with my laptop. I was talking to my friends when my laptop stopped and started making strange noises. You can't turn it off either, I've tried everything.

Take out the battery (if not soldered)

otherwise press the on switch until the notebook switches off

Thank you for your help. We already tried it, the only problem is that the battery is installed in such a way that it is very difficult to remove it. And the keyboard / mouse completely stops working
