At a guess, the current consumption of the CPU and GPU rises at that point, as X or Wayland switches to a higher resolution mode. If there's a poor contact in one of the power lines, it could cause the voltage to sag. > Bob Dunlop said > > Could be a simple loose connection, they can > > creep back and forth with time and > > temperature, > > I will investigate that. There is no graphics > card, but I check things generally. I would look in particular at the power connections to the board - the large ATX connector, and the smaller ATX12V one. If the power cables plug in to the PSU, check that end as well. > There is an old hard disk which I have been > unable to use ... > I am thinking I should disconnect the old disk, Definitely disconnect anything that's not necessary to boot, if only to rule it out. Remove the power from that old disk as well. If the connectors seem well seated and the problem remains with the old drive disconnected, my suspicion would then fall on the power supply. If you have a spare unit, it might be worth using it to power to board temporarily as an experiment. However, it could also be a marginal contact in the processor socket, or one of the memory sockets. This sounds like a temperature/expansion related problem, and they are not easy to diagnose.
