I did a system maintenance on one of my pcs and now they don't even boot up. I can't see the power up light even.

I checked all the power units they are fine though.

Why does this happen?

There are a lot of reasons why a computer may not boot up or power on. Of course, we will first need to check all the possible hardware parts that might be causing these issues before we start looking at other directions. Did you hear anything like beeping sounds when you tried to power on the computer?

You mentioned that you don’t even see the power light lit up. When you did system maintenance, can you describe exactly what was done?

If you had to unplug several hardware parts in doing the system maintenance to clean your computer, it is possible that you may have to check all the cables and make sure that they are plug in correctly to their respective ports. Sometimes, the power cord may have not been plugged in properly thus the computer was not able to power up at all. That is just the basic troubleshooting step and one way to isolate the issue.

If there is a beeping sound, can you tell us how many beeps were heard or if they are short staccato beeps or long ones?

Please send us the complete description of the problem so that we may continue with the rest of the troubleshooting steps to diagnose the issue further.

If you removed the parts or disassembled the computer when you did the system maintenance and now the machine is not starting not even the LED power indicator is activating, first, check the power cable connected to your CPU if it is securely connected at the back of the CPU. Next to check is the power supply cable connected to the motherboard.

See if it is plugged properly and securely to the board. Also, the motherboard normally has an LED in the middle which activates when the CPU is plugged in to the power. See if this LED is activated when you plug the cable to the power. Check the cooling fan of the power supply if it is working when you turn on the CPU.

If nothing is working, try checking the power supply to see if it is really working. You need to connect it to a working computer. Remove the power supply from your CPU then find a working computer. On that computer, disconnect the power supply cable from the motherboard then plug the power supply cable from your computer to the board.

After this, plug your power supply to the power and turn on the CPU. See if the CPU works. If the CPU starts then there’s something wrong with your computer’s motherboard. But if the CPU also doesn’t start, then the problem is with the power supply. In this case, just buy a new power supply for your computer.
