Lesson 10: Powering the computer on – build your own computer


In lesson 10 we’ll power the computer on, making sure that the fans are spinning and the lights on the front of the case are working.  In the Computer Setup lessons we’ll continue the steps to build your own computer.

Check Hardware Connections

Before we power the computer on we need to give all of the connections a once over.

Press down on the data cable connections on the motherboard and drives. It’s easy for them to come partially out while we’ve been working in the case.

Press down on the expansion cards as well.

Also make sure all of the power connectors are on solid.

We want to leave the cover off for now, so when we power the computer on, we can make sure that all the fans are running.

Connect the Speakers

Go around the back of the computer and plug in the speakers. Green is standard for the speaker connection on most sound cards and motherboards.

Then plug the speaker’s power cable into the outlet and power them on.

Connect the Monitor

Plug the video cable from the monitor into your video card and connect the monitors’ power cable into the outlet.

Connect the Keyboard and Mouse

For the keyboard and mouse check for a sticker which indicates the correct USB ports to connect them to.  On some motherboards only a few of the USB ports will be recognized in the BIOS.

Connect the Power to the computer

Then connect the power cable from the outlet into the power supply and flip the primary power switch to on.

Power on the Computer

Turn on the monitor and press the power button on the computer.

Look in the case to make sure that the processor cooling fan and the case fans are spinning.  With some motherboards, the CPU cooling fan will spin for a moment and stop.  The CPU fan won’t spin again until the CPU reaches a certain temperature.

All of the fans running and we can hear the hard drive spinning up. On the front of the case, we see the DVD recordable drives access light flashing.

You should also have video on your monitor, which we’ll go into in the build your own computer setup lessons.
