This morning there was a pretty intense thunderstorm over my house, my wife was home and said one particular thunder clap shook the house. My faithful old pc was plugged in but turned off. I have gone to use it this evening and found it cannot connect to the router. Inspecting the network cord in the back of the pc shows no network activity light and Win 7 keeps saying a cord is unplugged. Plugging the cord into my laptop and it works fine. The wifi also works. I can only assume the sound or vibration has damaged it? Its a old pc (Asus P5QPro mb) and its been to many lans and bumpy car rides over the years but I've never had this problem before. The usb plugs all seem ok so I might buy a usb wireless dongle for the short term. Just wondering has anyone else had this happen?
