Should I be worried?
In this hot weather I am turning the computer off occasionally instead of the usual once on stays on all day. The temperature software soon indicates 30º and the fan blows hard.
Just powered up and the desktop appeared as normal, it was populated with icons as was the taskbar. Sudenly they all vanished and only the desktop remained. It did this about six times as I sat and watched, then I switched off and left it for a few minutes. This time it's as per normal.
A one-off glitch? Or something saying goodbye?
