The blue screen of death!

I got very worried last night when my computer just crashed and the screen went blue with lots of writing on it!
I hurridly informed Graeme, who pulled a face and said that it could be very bad news as these things are sometimes called the "blue screen of death"! Anyway, like the hero that he is, he delved into the bits of the computer that I'm scared of and discovered that I had a (some!) virusses (ir is it viri??) since st somepoint my anti-virus software had been told to stop working - not by me :o(
It's now de-bugged and working fine. What a hero my husband is!
