Could you please tell me why my PC powers up and boots when I switch it on at the mains plug on the wall rather than the switch on the front of the PC?
I can switch it on from the front button, providing I haven't cut the power to the power supply IE switching it off from the three pin plug on the wall.
If switched on from the wall then the front button on the PC becomes superfluous, all I have to do is switch it on at the mains plug and the PC will boot up.
Surely this can't be right?

Yes that's the PC doing it's job. The small surge of power that goes into the PC tells it to go into 'recovery mode' as if the power had been interrupted. So it turns on and scans itself to try and recover what you were doing before the power was cut.

You should be powering down the PC by shutting it down in the start menu though.
