Anyone knows why my power trips even at the slightest lightning strike?

During one normal thunderstorm, it can trip for up to 5-10 times. My neighbour's power doesn't get tripped, while mine does.

Anyone can troubleshoot what component in the electrical system is faulty? It's very annoying when it trips when I'm doing something important on the computer. I want to fix this frequent tripping problem, I don't want to buy a UPS.

Thanks.
