Hi, well then, $15 is a good price for tuition fee. But do keep in mind that Presario is not standard. But not in a bad sense. I was lucky to learn how to build a PC in a factory, a cowboy outfit. So, I had access to all sort of components. This was back at the "486" days. Just to make a point, the largest hard disk at those days was only 20 Mb or even smaller!!! Not even 100Mb and their size, like a brick! Hugh. Sorry, digressed. You don't need to know everything in detail but you need to know what is going on inside the box. But the first thing you need to learn is to EARTH yourself, i.e. avoid building statics electricity on your side. I was not electronically trained, but I always keep one word in my head if I come into new territory in computer, LOGIC. I don't know the detail of how a computer works electronically. I have also noticed that as CPU advances in technology, the major components inside of the computer are more susceptible to damage by statics. With that in mind, and armed yourself with some good videos from Youtube, you can learn what plugs into what and how. And sometime, why in that order. By the way, just let to you know. What I learnt in the factory could not be found in any university (I was studying a Master in computing at that time). So, to sum up, to learn, keep the word "logic" in your mind. To build, earth yourself before touching any computer components. Good luck. And it is fun to have something to think about. It makes one feel "alive" and "useful".
