Before Powering Up

Before powering up the system, it's helpful to go through and verify whether all the components have been properly installed and that there are no connectors unplugged. You can also tidy up some of the cables in the casing as it will help to improve airflow within that confined space. Here's what the system should look like:-

If you've followed all the steps, you should have all these I/O connectivities lined up behind.

Here is a checklist of items to perform before powering up:-

  • Check the AC voltage switch on your power supply before connecting it to the mains. Never assume that the power supply has been set correctly to operate in your local AC voltage. Always double check this item, or you could damage the entire system due to incorrect operating voltage. Once you've done that, connect the power cable from the mains to your power supply. Remember to turn on the power switch on your power supply (if there is one). Users often forget to flip the switch before attempting to power up.

  • You should have a monitor ready, all connected and turned on. If you have an analog monitor, connect the cable to the VGA connector (the blue connector) on the graphics card. Those with a digital flat panel monitor with DVI support should use an appropriate DVI cable to achieve the best display quality.

  • Connect your mouse and keyboard to the PS/2 ports located at the rear I/O panel. The mouse connector is colored green while the keyboard connector is colored purple.

  • If you have speakers, follow the output diagrams and plug them into the provided audio jacks accordingly. There won't be any audio output at your first boot. You'll get proper audio only after Windows and the audio drivers have been installed.

    Once you've done all that, press the power switch located on the front panel of the chassis.

    The system glowing with life...
