Hi Andy,
I will admit it is a mystery. There is nothing wrong with the power supply, all the voltages are normal as read from the bios health screen as well as the fact it is an Antec 600W supplying about 300W.
I do think the main problem is the mother board - it is 2001 vintage as are the CPU, memory and other cards with the exception of the video card which is 2004 vintage.
The initial 175Hz 'tone' lasts for 1.3 seconds, presumably because they know the rather indifferent nature of rural French power lines
Yes I do know single and three phase power formulae having one of my degrees as an electrical engineer. Twenty years ago the nominal single phase voltage was 220v giving a 380v three phase this has since been increased to a nominal 230v (actually it is higher) with something approaching 415v three phase.
In the new year I have updating all the computers as a project. What motherboards we will use I haven't decided yet but they will be AMD CPUs and graphics cards. If anyone wants to throw in a recommendation I would be pleased to have a look at it.
