Installing an operating system may sound difficult, but you don’t have to do it alone. With any luck, there are people in your area ready to help!
Been using linux exclusively for at least 5 years, as the main OS for 10 years. The only time I remember the graphics driver breaking by itself, without me trying to do something dumb, was some 8 years ago with Ubuntu. This is not a problem anymore, with either Debian- or Arch-based distros.
