This process is called "booting up." It takes only a couple of minutes, but it's the most important minute of your computer's working day. Unless the hardware and software communicate properly, nothing else on your PC will work. The first two minutes after you switch on are vital to the performance of your computer. Here's what happens after you press the power button:-

-- The sound you will hear is the turning of the fan. This takes care of the temperature inside the system. Do not cover the vents on your computer because it will caused overheating. The first task the computer performs when you switch it on is the power on self test routine. This check the important components such as the hard disk and detects any serious disk errors. When the self test is done you normally will hear a beep.

-- The computer then reads the Basic Input/Output System to communicate with memory, the hard disk and the monitor. This will also send simple messages to the screen and will look up the computers settings and the date and time. It also start each component while you see the memory counting up on the screen.

-- The operating system is then read from the hard disk and loaded in the Read Only Memory. Your PC will read special configuration files, such as the country your computer is located in which this allows it to use the correct language and time settings. At this time the starting Windows screen is displayed if you're using Windows.

-- At this point, it will play a sound when it's done loading and initiating itself. It reads a sound file from the hard disk and directs the sound output to the speakers. This is done to test the speakers and test that the operating system is working properly.

The Desktop is then displayed ready for you to use. Every command you input into your computer either by moving and clicking the mouse or by keystroke on your keyboard passes through the Random Access Memory which is the memory used by your computer temporarily to store the files and programs you are working on.
