it is serious..and it is worth it...the best method of protecting your computer from lightning is to turn it off and unplug everything from the wall...all power cables, phone lines, network connections....and just not use the machine during an electrical storm....if that's not doable (such as..if you're on vacation)...having a good surge protector (i use triplite) is the most logical home option.....you could also get a UPS (uninteruptable power supply i use APC)...that will not only protect you from lightning..but it will also keep the computer on long enough for you to properly shut it down during a power outage

Yup...unplugging is the way to go. If it's a really bad storm, I'll throw the main breaker to the house. Besides a ups, the next best item is a inductor based surge protector. I bought a couple from Brickwall. I got em on sale for $120 each. Today they are something like $170 each. Pricey but it's the last surge protector you will ever have to buy. When I bought them, they were the only products on the market that could meet military standards.....

Basically if you have a power surge, excessive power will go into everything you have that is plugged into the wall outlet. This is never good. This can probably fry every component or simply break it..

Yeah, the PSU in the pc is basically a little power trasformer and on cheapo ones especially any fluctuation in the supply results in some large effects on the power delivered to the system usually enough to break it. A surge protecting multi plug adapter is just basic kit for any PC or electronics, a UPS is a good idea in the states, as you guys get alot of lightning i saw more lightning in one storm in the US than i ever have in my whole life in scotland(to far north for lightning really). For most if you have a modern electrical system in your home the breaker will catch it before it does damage but if you have older electrics then a bit more protection is always a good idea.

Lightning can flash by power lines a few miles from your home. It doesn't have to hit the lines. All it has to do is pass fairly close to a power line. It will induce a voltage charge in that line and it will seek out the path of least resistance. If my main breaker is open, this represents a lot of resistance and the charge should continue down the line.....

I have two of the ones in the second link. I never had a surge so I wouldn't know if it would do it's job. So far, though, it has been great.
