There's a difference here: this is an actual shut-down, not a freeze. > Makes you wonder! Good idea to eliminate as much software as possible - > obviously suspect any new additional applications/modules/Absolutes etc Well, I tried John's suggestion and shut down more or less everything: I didn't know whether the picture could be put up here, so it's at http://www.johnwoodhouse.co.uk/Tasks.jpg You can see that more or less nothing in software terms was running and yet it still shut down. This seems to me, unless I have missed something, that it rules that out? It seems to keep coming back to the PSU: why, if power is on, does pushing the power button on the front not work? In fact, this morning I had to cycle the rear switch twice before it would come alive. Doesn't that suggest something to do with the PSU? Is Chris Evans reading and have a clue?
