Typically what happens is silent corruption. Rarely, very rarely you'll get a crash, but even if a bit flips inside of program code there's no guarantee that that code will ever run again -- and if it does, the malfunction might not be obvious. Most memory is non-program data, however, and most non-program data won't cause obvious errors if corrupted. A picture that renders incorrectly, a broken model in a game, a single burst of static in a video... It's insidious precisely because it's hard to notice, and corruption never gets better over time.
