If you push the power button and nothing happens, start with a check list, to rule out something really simple.

Check List

  1. 1
    Don't panic
    Most people get into panic mode when they realize their computer won't start. People get frustrated because they cannot access their files. One of the reasons why a computer won't start is the failure of a piece of hardware. In most cases, it's usually not the hard drive that stores all files.

  2. 2
    Check the power
    Before start the troubleshooting process, make sure that:
    1. Every power button and switch on your computer is turned on. The power button can be found on the front of your computer or at the back.
    2. Also check the power switch on the UPS, surge protector or the power strip.
    3. Make sure there isn't a problem with the actual outlet by unplugging the computer, and trying plug something else in, and make sure it works. Don't forget to plug the computer back in after this test.
    4. Make sure that the power voltage switch has been set correctly: The input voltage of your power supply must match the correct setting for your country. It is possible that the two do not match; hence your computer won't turn on.
    5. Check for a disconnected power cable: It is possible that your computer won't turn on because it is unplugged or there's a loose power cable. It is important to verify this.

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 in your Laptop.
  • Plug in the computer. There has to be a light indicator somewhere stating that the computer is plugged in. 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 thing that isn't working correctly. You may need to open up your computer to check if the connection inside is well, connected or not. The problem with the connection is one of the most common reasons why a Power button isn't working correctly. Oftentimes, especially in the case of laptops, it's because the Power button is located near the hinge and it breaks apart after a while.

The main problem with my computer.

When I press the power button my CPU doesn'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 opened it up. I tested my power supply by pulling out the ATX connector - the largest connector, then I inserted paperclip into the ATX connector -the green wire and the black wire. Then I tested it. My power supply runs. Then I reconnect my ATX connector into my motherboard and when I turned it on, nothing happened. I guess it would be my motherboard, power supply, or the power button. That is all.

It might 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 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 the shadows are even. If the pins are bent or not completely straight - straighten them.
  • 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.

My desktop takes 20 minutes to start but if I do a restart it restarts immediately.

If I shut down my computer and then start it again I get a black screen after that I have to remove the power cable from the tower and plug it back in to get my home screen and that too after 7 minutes approx. I have tried: Don't have a clue. I think it was caused by: I don't know

Power Button doesn't do anything - how do I fix it?

Computer works fine, but over the past four days it took several attempts to get the power button to work. Thought putting it to sleep instead of shutting it down would work but hitting the space bar or the mouse isn't waking it up.
