Answer:
Explanation:
First, you should make sure the power cable is properly connected to the pc and the wall plug. Next, you need to make sure that the power switch on the PC's power supply is turned on. If the PC still does not turn on, you may want to check if the wall plug is providing electricity. If so, the next step would be to check the inner cables connecting the power supply to the pc and make sure everything is correctly connected.
If you have tried all of this to no avail then the most likely reason is that something is broken. The possible culprits could be bad cables, broken power button, bad power supply, or failed motherboard. You would have to individually test each component to find the culprit.
