If Your Computer Turns on But Nothing happens

When you try to turn on your computer & you hear the fans running & the LEDs lighting, but nothing else happens. That means your power supply unit is working properly. The keyboard & mouse would also light up. Follow the following steps. 

• Unplug your computer from the wall. 
• Hold on to the power button for 10 seconds. 
• Release the power button & replug your computer back into the wall. 
• Turn your computer on again. 

If your computer has any leftover power Then this should purge it. It should fix the issue & your power supply would be fine like before. 

However, if you find that your computer is not turning on at all, not even the fans or LEDs. These are some things you can do to diagnose the problem.

Checking the Main Power Source

Check the outlet where the computer is plugged into. Test if it’s working fine for other electronic components like phone chargers. If it does work then that means the power is working fine, your computer has some problems.

You can do the same thing by connecting the computer main plug to any other power outlet. 

Check Internally

Now as you know the issue is within the computer, you need to see if there are any components that are working with the power on. Open the side panel carefully & while the computer is unplugged. 

Check the fans carefully, try giving them a boost with a stick. If nothing happens, there is likely something wrong with your Power Supply Unit (PSU). The mouse & keyboard should also light up if there is a hint of power coming from the PSU. 

Your fans are directly connected to the PSU. If the motherboard is damaged but the PSU is okay, then the LEDs & fans should have worked. If you are a computer nerd, then you can try checking each item if it works properly. 

But to that, you need a second computer to see the items one by one. Many don’t have a 2nd PC to test every item. That’s why now the best option is to go to your local computer shop & check what the problem is.
