Computer technology changes so fast and usually the computer we use lags far behind. New programs use up a lot of memories and buying a new computer everytime Intel rolls out a new processor gets so expensive. I found a website called www.easyasmypc.com that will help you solve that problem without causing a lot of money. Having had the experience of building my own computer, I can tell you that it is very easy.
They have custom build pc kits, these kits include all you need to build your own computer. The instructions are written in plain English, not in a hard-to-understand technical jargon. It also has illustrations which show step-by-step instructions. You just need a screwdriver and the Easy As My PC Kit to build your own computer. Easyasmypc.com also has kits to increase your computer's memory or RAM or even replace your old CPU.
