What causes computer motherboards to burn out?

Answer hi: most times it is either a bad power supply fan or either a CPU fan ,and sometimes a power surge,also they get dirty inside . Heat and dust are a killer to any computer. I do hope this helps someone.

Ron it also happen due to ESD (Electro static discharge).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
