How do you replace the mother board in a computer?

Basically you have to strip down the motherboard in the tower by removing the modem, video card, etc. You will need to swap the processor and the heat sink and anything else the new mother board does not come with. you will need to disconect all of the wires that are attached to the motherboard and then remove the screws, which will probably be upwards of 15. Once removed everything goes back together just as it was removed.
