Check on the net first on a reliable pc site first as I have done in the past and they usually come up trumps. Helped me out big time when the main pc lost the internet and the other pc was ok.
Around two years ago the pc that my son was on suddenly made a noise and sparks started to fly and the pc went off that he was on. As it was such a dramtic thing to happen (for me anyway) I went to one of my neighbours who is a PC Technician to ask his advice. Turned out that the PSU blew. He said we were lucky that it didn't blow the motherboard too. I switched it off pretty quickly at the time so that I think saved it perhaps.
So it is lucky to have some people around who know what they are talking about.
