Content Creator in need of a new Tool.

Some years ago, my mother bought a computer for her job. It was really good, had a nice performance, but then my dog pulled from a cable and it fell on the floor. It was a Dell Inspiron. I've been trying to save up some money, but where i live it is hard to make public work. And it does not help that I am only 17. I couldnt get a serious job. This computer is so slow, it doesnt let me even open simple apps anymore. I'd love to create content, because im really into videomaking. I really have a gift, and would love to use it to make people laugh and feel happy I know it is not a Huge deal, like others in this site, but I would so much appreciate. Sorry for my english by the way.
