Assemble PC - PART 3

Install Motherboard Into Case

-Now with all that mess of installing RAM and a CPU it time to throw it in the case. (not literally) With motherboard aligned with your standoffs/motherboard spacers simply put the motherboard in. Now pay attention to the I/O shield which your ports go into. The I/O shield will tear easy so be careful. Now with motherboard in place go ahead and use the screws that came with case and screw in snug. Make sure there are no standoffs that are in wrong place and not being used. You do not want a standoff touching the circuitry on the motherboard. Take care also that none of the standoffs are on the wrong thread. If they are not screwed in on the right thread they may be at an angle to the motherboard and cause stress to it by not allowing it to sit flat.

Hook Up Connections

-With the board in place we will go ahead and install the leads to the board along with the power connector. The leads I speak of are little wires that usually run from front of the case. They will be marked with speaker, power, and so on. Look at your motherboard manual to see which ones fit on the board. There is usually a block that allows you to plug them on to. If you put them on wrong don't freak. This will not ruin anything you may not have lights working on the computer an worse case scenario is the computer wont start. There is one led that is especially important and that is the power switch. If you are using a ATX or BTX board (AT is now defunct), there is a led that will plug onto two pins. This will actually work the power button on the front of computer. Plug in led connectors now.
-Now lets plug in the power connector from the PSU. This connector is a 20 pin connector or prongs. This connector only fits one way and you cant screw it up. Simply plug into motherboard using the motherboard manual as a guide. Newer CPU's also require a 12v connector plugged into the board. All PSU's have this connector, it has 4 pins in a square shape and it usually has 2 yellow and 2 black wires from it. 

Hard Drive
-On the back of the hard disk you will see a power connector and a jumper. The jumper is to set the drive as a Master or a Slave. If you are running one Hard Drive you will want to set this as a Master. Simply take the jumper and set to the pins that note it as a master. Real simple just look at the back of drive. Pins are in a vertical fashion. Set jumper over pins and you are ready to slide that puppy in. New SATA drives don't require you to set any jumpers, and new ATA133 drives auto sense master and slave settings.

-In the case you will see most of the time a place that is marked HDD and FDD. This means Hard Drive and floppy drive. If you have a ATX minitower the hard drive will more than likely install on the bottom drive bay of the case. This is so on most modern towers. You will want to install the drive by sliding it in the bay with connectors facing the back of computer. With Hard Drive installed simply take at least four screws and snug it down.

 
Floppy
-This is about the same as Hard Drive. You will not have to worry about the jumper setting though. Simple slide the floppy in through the front of case in you desired spot. Make sure that the front of drive is flush with case. This is purely for cosmetic reason only. Tighten floppy down from the inside of case.

 
CD-ROM
-You will have a jumper on this one also. Depending on the number of hard drives, and the number of CD-ROMS you have, the master and slave setting will vary. If you have two hard disks, they will be on a different IDE channel to the CD-ROM, as each IDE channel can only support two components, so you set the CD-ROM to master. Now take drive and slide in through front of case and screw it down snug. Again make sure that the CD-ROM is nice and flush with front of case for cosmetic reasons.
