Thanks ZW,I am sure I did that though.It needed a format anyway,there were other issues that I needed to address that a format and re-install would cure.
Anyway I am back now,drinking Gin and waiting for Steam to re-install 90 gig's worth of games.Slow isn't the word,and I am running out of Gin
Will try TvT tomorrow but I am sure it will be fine.
Chucky.
