Here's a list of events:
decided to switch on my computer, just like most mornings
made start-up noises, so far so normal
just about to turn on the monitor
made a noise from the CPU, sounded like it was shutting down
computer shut down (automatically)
computer started up again (automatically)
computer shut down again (automatically)
started up again (automatically)
it's fixed itself now but I'm wondering if there's something wrong or if this was a one off
