I recently faced a problem with my system unit. I was using my PC during a thunderstorm and was just about to turn in off, when I saw a fireball like spark emerge from the internet line and my PC shut down completely. Now am I unable to turn it on. Can anyone help me please?

Thunderstorm damaged my PC- how to fix

Hello. It is most likely your power supply that was affected during the storm. All you have to do is unscrew the frame. There will be other components plugged into the supply so simply unplug and remember where they were plugged in. With care, dislocate the power supply source and find an exact replica at a local electronics store.

Thunderstorm damaged my PC- how to fix

Hi James!

 

I know how frustrating this situation is but let’s check first the basic parts.

 

 

If there’s a fluctuation of electric current the part of your tower (CPU is inside) that will be greatly affected will be the power supply. Try to dismantle your tower and check the power supply. Try to look inside power supply. If there’s any short circuit you’ll see some of the parts inside power supply will turn to black or “burnt.” Inside our house we can use from 110 volts up to 220 – 250 volts. 

 

 

Lightning can reach thousands of volts per struck. You can go to any computer repair shop and they can test if only the power supply is affected. If they will simulate it with a compatible power supply and that doesn't work. You know the answer to this.

That sounds more like the power supply is busted. You need to check first if there is power in your CPU. Plug the CPU to the power and turn it on. Now, see if the LED power indicator on the CPU activates. If there is no reaction on the power indicator and it remains off, you need a replacement for your power supply.

Bring your CPU to a computer shop and have the power supply checked. If they verify that the power supply is damaged, you need to replace it. Ask them to replace the power supply if they have one available. On the other hand, if there is no problem with the power supply but the CPU doesn’t turn on, it means the motherboard is damaged.

Unfortunately, in this case, you have to purchase a new motherboard. That fireball-like spark from the internet line must have damaged parts of the motherboard. When buying a new motherboard, go for the same socket model and memory slot type so you can still use your processor and memory modules.
