The following are some of the instructions that you can apply if your computer is not working:

  1. 1
    Do not panic:
    Most people get in the panic mode whenever they realize that their computer won't start. People get frustrated because they cannot access their files. One of the reasons as to why a computer won't start is the failure of a piece of hardware. In most cases, it is usually not the hard drive which stores all files.

Questions and Answers

How to check if the Power button is working correctly?

A computer may not turn on for various reasons such as:

  • Power source is not working.
  • There are some problems with the power cable.
  • The connection of the Power button to the power source is damaged.
  • There is a short circuit somewhere inside the computer.

In order to check if the Power button is working correctly, you can do these:

  • Remove the battery of your Laptop.
  • Plug the computer. There has to be a light indicator somewhere stating that the computer is plugged. If this is working, it means your computer is able to get enough power from the power source and that the power cable is also working.
  • Press the Power button and see if your computer turns on. If not and the plug indicator is on, it means that your Power button is the one that does not work correctly. You may need to open up your computer to check if the connection inside is working or not. The problem with the connection is one of the most common causes why a Power button would not work correctly. Oftentimes, especially in the case of laptops, it is because the Power button is located near the hinge and it breaks apart after a while.

The main problem of my computer?

When I press the power button my CPU didn't work and I can't see the lights on my fan, so what I did is disconnect all the cables from my computer and open it up so I test my power supply by pulling out the ATX connector which is the largest connector then I insert paperclip into the ATX connector the green wire and the black wire then I test it my power supply runs, then I reconnect my ATX connector into my motherboard and when I turned it on, nothing happens, and I guess it would be my motherboard, power supply, or the power button? That is all.

It can be

  • a faulty motherboard 20+4 connector (remember to insert all of the pins (either 20 or 24) into the motherboard);
  • a faulty CPU connector or wrongly inserted CPU 4-pin connector; make sure that you have plugged it in correctly, not upside-down, as it is possible;
  • bent pins under the CPU in the socket; shine a bright light to see if shadows are even and straighten the pins if they are not;
  • too much power drainage; your PSU must supply enough power to your components. For example, a weak 300 W PSU will not run a system with LGA 2011-3, i7, and Ge-Force Titan X in SLI;
  • a faulty CPU;
  • a faulty motherboard.

To exclude any faulty parts, use them in other systems or use other parts in your system to test them. For example, use a PSU on another working system.
