Best Answer

What happens is that when you press the power button it sends an electronic signal to the motherboard, the motherboard is designed to start the power-up routine when this signal is received so first it activates, then the BIOS becomes active and starts the various components of your computer. Once everything is started is displays the BIOS screen and then the Hard Drive is spun up and windows starts loading.
