I like to build my own PC and also help friends. Most PC gamers also build their own PC. Most parts come with instructions and almost all pieces fit nicely, its kinda like building Lego. I switched to Linux a couple of years back. But last month I helped a friend build a PC and when installing Windows 10 it just said "missing drivers" with no clue. Then my friend went to a computer shop and they installed Windows without any issue.
