Don't forget while you're saving up for a new computer to estimate how much you want to be spending. This will give us an idea of the dollar amount per part. You having no idea how to build a computer doesn't mean a thing! However it will cost you a little more money. When you're ready, gather parts and ideas for your PC as recommended by people here. Then, order all these parts and when you have them all in hand (oh the glorious day), take them to a Computer Outlet Store or a similar location. They'll charge you a 'service' fee or an hourly fee, but again you'll save much more money by ordering the parts yourself you'd hardly notice the difference! Good luck!
