Sort of clammed up a bit though, when he saw the screen. I had opened a command prompt and expanded it full screen.
I asked him what he thought it was and should I be worried
Nice guy though, he suggested that my PC had a "hardware fault" causing a "faulty display"which he offered to diagnose for me for a fee of £35. Wasn't that nice of him
I still remember the days when a black, or even green, screen with a C prompt was all you saw after boot-up. You could do exactly what you wanted and so very fast and WITHOUT all the different error messages you get with a GUI.
