When you say 'just a moment' do you mean less than a few seconds?  If
so then it would not have got past the bios startup so it would likely
have to be a hardware issue of some sort.  I have a PC where the power
button sometimes sticks in, so the effect on startup is the same as
pressing and holding the button, so it starts up then shuts down
again.  Could this be your problem.

That shows 40 seconds of startup, presumably from the successful second startup.
