I wanted to know what I can do about my laptop making loud noises and sometimes just going out.
It overheats and switches off before it breaks due to overheating
Things are getting too hot because your laptop is not designed to play / play Fortnite.
The laptop is overwhelmed with Fortnite either you clock the cpu / gpu down or you buy a new one
Your laptop will probably get too hot and will therefore switch itself off. You should dedust them, if you know little about laptops I would have a specialist do it for you.
This could be the fan of the processor or graphics card, which somehow no longer cools properly. From then on I would strongly avoid playing and looking at what's going on with the fan. Maybe there's some dust in there that is blocking something.
