I’ve just installed the new power supply for the server. It had crashed 3 times in the time it took the package to arrive. So – I’m going to let it run for a while and see what happens. I’m confident that this will solve the problem – after all: my server has more than a few power-hungry parts in it. If it lasts over a week [I think 5 days is the record], then I’m going to claim victory over the reboot issue.
