Physical Damage

Dropping your computer's case can warp and crack the motherboard. If the board is bent or scratched during installation, this can also cause it to fail.


A computer case that has insufficient cooling or is in a hot environment can overheat. This can cause the motherboard to warp and some of the parts to melt.

Electrical Surge

A lightning storm can hit an electrical pole and cause a surge of power to flow through your residence's electrical system. The surge can burn and melt a computer that's not equipped with a surge protector.

Temperature Fluctuation

A rapid change in temperature can cause the internal components of a computer to permanently warp, rendering them inoperable. This happens a lot with laptops: People leave their laptops in their cars during a heatwave or snowstorm, then they bring their laptops into a climate-controlled environment.

Faulty Power Supply

A damaged or improperly manufactured power supply can send too much electricity to a motherboard, frying its components.
