Hi guys, Found this site from a google search trying to solve my problem and you guys look like you know a lot so here's the problem: Last night a lightning strike killed my cordless phone system and power to half my house. The desktop (HP Pavillion, Windows 7) is connected to a power surge strip, and everything seems to be working fine... it's connected to the modem which then goes to a router and the laptops in the house have an internet connection. But NOT the desktop! We can't connect no matter what we do. We've gotten random error messages, but one keeps telling us that we do not have a valid IP address. But the other computers will connect, so is this even possible? We have tried turning off the modem and router and restarting them, rebooting the PC, system restore to pre-lightning strike. We don't know what else to try. Help!
