PS - I just transfered this from the Vista Forum.
Further to the statement this was just the last event in a series of events. First it got slower and slower, then when you were on any website it would keep jumping back to the sites homepage. My wife said she cleaned it regularily with CCleaner. I checked it out, ran all the usual tests, it's clean and clear.
Regarding the Internet connection problem, it was fine, then it wouldn't connect. Then it was asking for the password, when it was given it said it wasn't correct and/or it didn't recognise it. So I tried with the ethernet cable and it connected. Then I unplugged the cable and it stayed connected. Until I turned the laptop off and on again, now though it won't connnect at all without the cable.
Any theories guys. My thought is that perhaps the laptops receiver has packed up and needs replacing?
