It's not something we like to think about, but your computer will fail if you keep it long enough. It may be a simple problem, such as the floppy drive not reading the disk to a major system crash.
Because operators run computers, User Error is the most common cause of computer malfunction. When the user is at the computer, they may add or delete specific files. Or they may remove or exchange certain hardware features.
