I love the tech advances in desktop computer hardware.?

I'm 19 years old and I have latley found a love for computer hardware. I dont understand the inner workings of processors, gpu's, motherboards, etc. but am very interested. I would like to go to school and research computer hardware design and trying to make hardware more powerful, efficient etc. What should I focus on in school in order to recieve a well-paying career in the field of computer hardware development, building , innovation and design? What companies would I most likely work for? Thank in advance, Kyle.
