Hi Brendan,
Perhaps a power supply issue.
Power supplies can do weird things. It could also be that you have added things over time to your PC and the power supply is at its limit with the power.
Perhaps when you first turn power on, some devices power up and reduce the initial load so when you then turn on PC, the rest powers up.
How many watts is your power supply and do you power lots of devices including external USB's.
Not exactly sure what you mean by holding the power button down on as normally it's just a quick press and you let go, you should never actually have to hold the power button down.
On all modern PC power supplies, if you hold the power button in for 6 seconds, the power supply will switch off.
Hope that helps.
Cheers,
Damien.
