In lesson 1 we'll go over all of the components of the computer and the tools needed to assemble them. Make sure you watch all of the build a computer video lessons before attempting to assemble your computer.
Let’s go over the components we’ll be installing.
First we have the hard drives. We’ll be installing 2 SATA hard drives, each with connections for data and power cables.
- A SATA DVD recordable drive with connections for data and power cables
- 2, PCI Express 2.0 16x video cards, a PCI wireless network card and a PCI Express 1x sound card
- 3, 1GB DDR3 Ram sticks
- Processor with heat sink and fan
- The motherboard
- The computers case
- The power supply
- An extra case cooling fan
- Serial ATA data cables for the 2 hard drives and DVD recordable drive
- A power strip with surge protection.
The tools we’ll need
- A Phillips or plus screw driver
- A flat head or minus screw driver
- A power screw driver is optional
- Needle nose pliers for getting into tight spaces or to retrieve dropped screws
- And a parts container to hold the small screws while you’re working and to store extras
Using a Power Screw Driver
When using a power screw driver be careful not to over tighten the screws. It’s easy to strip the threads which can ruin the part. If you do strip the threads try using another screw with bigger threads in the hole.
To reduce the likelihood of this happening, hold the power driver very loosely, so when the screw is tight, the driver will slip in your hand. Under no circumstances use a power drill with a screw driver adapter.
Types of Screws
Inside the case you’ll find a bag of screws. You can use the parts container to separate the different sizes and types of screws to make finding them later a little easier.
There are two basic types of screws: screws with little threads and screws with big threads. The screws with little threads are used on DVD and Blu-ray drives. The screws with big threads are used on the motherboard, hard drives and add-on cards. There are exceptions, but the general rule is if a screw doesn’t fit in a hole, try the other kind of screw.
Front Panel Connections
There are several cables coming from the front panel that control the power and reset buttons and also light up the hard drive activity light. Some cases also come with cables for a sleep button, power light and case speaker. There are USB, Firewire and Audio cables coming from the front panel as well. We will connect these cables to the motherboard in lesson 3.
