Why is it when you get an electrical outage in the house the PC does not turn on anymore.
If you have had this happen then it is most likely the Power Supply in your computer that is fried and just needs to be replaced.
What happens is when the electricity comes back on there is a tiny power spike. This can fry other things and not just the computer but mostly the computer because it is very sensitive to this. This is something that a surge protector can help you avoid but not 100%.
