Questions and Answers
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
