There can be a lot of problems with computers, and one of them is the case of your computer not switching on at all. There can be multiple possible reasons behind this problem, and I am going to list a few of them. Some of them are even too obvious for people to realize that this might be the problem:
� Did you make sure that you pressed all of the power switches �On� or �1�, so that your computer is receiving power in the first place.
� Is your computer�s power supply working?
� Your computer might have been overheating, and your CPU or other components might be damaged.
� Some of the cables might be loose.
