Because computers are run by operators, User Error is the most common cause of computer malfunction. When the user is at the computer, he or she may add or delete certain files. Or he/she may remove or exchange certain hardware features.

A large percentage of computer malfunctions are due to environmental factors such as power surges caused by lightning, resulting in over-voltage.
Another cause for failure may be room temperature being too high or low, as well as dust, dirt, or sunlight. If you're in business and heavily dependent on your computers, such factors as room temperature, sunlight and protection against power surges is of the utmost importance and simply cannot be overlooked.
