How To Check If Lightning Damaged Your PC

When your PC doesn't boot and you suspect that a lightning caused it, here's how to check it up.

First, unplug the computer, open it up, and have a look. Have a sniff, too. An unusual smell may lead you to the damaged piece.

It's probably the power supply. That's where the electrical spike would come in, and it's thus the most likely component to be damaged. Luckily, power supplies are relatively cheap and easy to replace--some cost less than $40. Of course, if you have to replace your power supply, you should get one that will cover your needs.

Take a good look at the motherboard, as well. Look for swollen, blistered, or charred areas. Replacing the motherboard is considerably more difficult, and effectively means replacing the computer.

If the power supply and motherboard don't seem harmed, remove the RAM modules and examine them for damage. They're relatively cheap and easy to replace.
