Installing the memory

Before we install the motherboard we will install the memory. It doesn't really matter what type you have the process is similar. The memory is keyed ie it has a slot so that it can only be inserted one way. To insert the memory make sure the two latches are apart. Again note that the memory is very static sensitive, take the usual precautions earthing yourself on the case etc. Start with the lowest numbered slot on the motherboard (usually slot 0). As you push the memory into the slot. You can use a bit more gusto than you did with the processor, although don't go over the top. The levers should start to close. If the levers haven't fully closed then squeeze them both together and they should latch the memory into place.

To remove the memory, just pull the levers apart and they will automatically eject the memory.

Installing the motherboard

Now we are going to mount the motherboard in the case. Providing you have shopped correctly, your motherboard is matched to your case. You will find, probably in the little bag that came with your case some spacers that will allow you to mount the motherboard on one side of the case. It should be obvious which side, as there will be a metal plate there slightly bigger than the motherboard on which to mount it. You will find a number of plated screw holes that you can match the spacers to and there should be at least a couple of mounts on the case that you can screw a screw into. If you are having difficulty orientating your motherboard to the case remember that the PCI slots will have cards plugged into them that will point out trough the slots at the back, Also the ports (LAN, USB, PS/2, parallel etc) will all have to fit though the slot for the backpanel. All this will be covered specifically for your case in your case instructions, so read them carefully. It is important to make sure that the motherboard is not touching the case at any point as this will almost certainly short circuit something on your motherboard and render it a piece of junk. Also make sure that you do not drop screws down the back of your motherboard. The space is usually just big enough for them and they will have the same effect as touching the motherboard to the case directly.

  Now it is time to connect up some of the cables. Assuming you have an ATX case (almost all modern cases are), then we are going to connect the ATX power connector
20 pin standard ATX cable connected to motherboard.  
  The more modern motherboard / processor combinations are so power hungry that they require an auxillary power connection in addition to the standard ATX power supply. If you look on the motherboard to the left you will see an ATX power connector and a 12V ATX connector marked. These should both be plugged in using the corresponding leads from the power supply. Older motherboard/processor combinations require no aux. power.  

Fitting Cards

Fitting the sound and video cards is not difficult. Like the memory slots the PCI and AGP slots are keyed. This means that the cards can only be inserted one way. As usual taking antistatic precautions, take the graphics card from the antistatic bag and push it down into the AGP slot. Look along the length of the slot to ensure that the card is not sitting up at either end. As you have a choice of PCI slots to place your sound card, network card or other PCI slot cards in try to keep them as well spaced as possible. Chances are you AGP mounted graphics card will be running hot, some of the more expensive one even have fans. Try to avoid using the PCI slot next to it, just to encourage a cooling airflow around your case. Again follow the specific instructions that come with your motherboard and cards.
