Hi,

It seems I have a power problem with my computer. When I try to start my computer, the cable does not find any power supply. The power supply fan does not run and there is no power supplied to any other part of the computer.
 
So what can I do?

Khaled_mithun,

  • There are many suspects or probable source for your computer's power problem. 
  • First of all, you need to check you power cable. Sometimes power cable becomes faulty every time they are over stretched. Try using a new power cable and connect it to your PC.
  • If using a new power cable does not solve the problem, you have to check the next part. The Power supply. 
  • Does the fan of the power supply rotate? If yes, then It is not the culprit. If no, then you have to test the power supply stand alone. Meaning, removing the power supply from the motherboard. You have two short pins, colored Green and black. You need to use a metal paper clip, bend it to a U shape, bringing each end close to each other.
  • Look for the green colored pin of your Power Supply Unit (your PSU can be 20 or 24 pins). Insert one end of the paper clip to the green pin and look for a black colored pin and insert the other pin. Plug the power cord to the wall outlet. If the fan of the power supply unit rotates, then it means that your Power supply unit is working and if not, then you have to buy an new power supply unit.
  • You can try this steps and see the result.

Post back the result, so I can keep a track and help you more.

  • Computer fan plays important role to keep computer going. Fan does rotate and this gives your computer an indication that it's working, creates power and supplied energy to the components inside.
  • When identifying power supply issue, the power cord must be check first. Power that goes to the computer CPU going to the outlet or surge protector.
  • I once encountered power issue, as my power adapter explode when I connect my computer power cord to it. I then discover that the power cord itself is causing it and it gets hot fast.
Replacing power cord and consider the power surge protector can fix this issue
  • Replacing power cord and consider the power surge protector can fix this issue. Power adapter is cheap depending on the model. It could cause you around 5$ to 30$, better get with high quality power cord than the cheapest to expand the life span of your computer.
