The motherboard is the most complex component in the whole computer (from the user's point of view) becouse everithing connects to it one way or another and the settings that determine the functionalyty of the system are made on it.

You need the motherboard manual. If you don't have such documentation it's imperative to get it. Try to find out the motherboard's manufacturer and model. It is usualy written down in paint somewhere on the printed circuit board with larger fonts. If that doesn't work out, locate two large chips (the chipset) and search in google for " documentation manual guide layout" it should return relevant results. There is no way to guess the functions of jumpers.

On this specific motherboard, we have:

Now that we have gone thru the motherboard connectors, proceed to make the jumper settings according to your processor specifications; adjust RAM speed and voltage.

Fitting the motherboard in the case. In theory, you should now have your motherboard with the CPU, fan and RAM modules mounted on it plus all the jumper settings made. The trick is that you fit those first becouse inside the case it's a tight area where you can't move your hands easily. First remove the tins of the case (usualy take off the outer screws in the back side). Inside the case there should be a thin board with some plastic round things to suport your motherboard. Your skills should get you thru that. Now connect the AT or ATX suply and leave it like that. Take care of unwanted cords and plugs, you don't want to have any short circuits. DO NOT PLUG IT IN!!
