My house seems to have an invisible target for lightening on it. I have had to replace my modem 3 times in about 6 years. The first 2 times it was still under warranty, so a service tech came to my house. This last time I was on my own.
I called the Quality Computer Systems shop because it was the only computer fixer-shop I knew of, to be honest. The owner was incredible helpful and replaced my modem quickly. I had my computer back in a couple of days.
