Go crazy means to lose your mind, and in conversation it can also mean to get wildly excited or furious. In the first sense it is almost always an exaggeration: people use it to complain about boredom, waiting or noise, not to talk about illness. The second sense describes a strong reaction: fans after a goal, or a dad who spots a scratch on his new car.

Become is the usual verb for a change of state, so become crazy can look logical. But when a state changes suddenly, and usually for the worse, English uses go: go crazy, go bad, go blind. Become crazy sounds unnatural, so become was changed to go.
Go crazy is about losing your own mind, while drive someone crazy means making another person lose theirs: His constant phone calls are driving me crazy. In British English people often say mad instead of crazy: I'll go mad if it rains all week.
