M1ABD went off the air at around 1700 Hours on Thursday (26 February 2015). I managed to fit a trip up the hill in on Friday morning.
I found the computer was locked up. There did not seem to be any other problems at all. The only way I could re-start the computer was by switching off the Electricity and turning it back on again. The computer burst back into life and started working normally.
I am starting to think this is some sort of software problem. It is difficult to know what could be causing it though, as the computer on has Windows XP and UI-View32 loaded on it.
Time will tell I suppose.
