Although this had intel and amd involved, i dont think its worthy of that thread because they are sooooo old!!! My dad has two old computers at his house, about 5 years old. I had a look at them and this is what i gather they have. Computer number 1. - 64mb RAM - Pentium 2 (II)processor. - 15gb harddrive - Windows millenium edition. Computer number 2. - 128mb RAM. (two 64's) - AMD Duron processor. - 4 gb harddrive!!! - Windows Millenium edition. Im gonna use 1 of these as a project comp, for a bit of practice of getting to know the hardware of computers. Right now i have no idea what im on about, i can just about swap over a memory card/stick thingy (RAM thing) to the other. Do i have to install this on the comp when i swap it over\or anything? Now, processors!!!! I've already said im a rookie at this so please be patient lol! Which one is the better out of the two? I've never even heard of them. Also, can i buy a new processor like pentium 4, and put it in whichever computer i choose to keep as the main? How much is a p4? Do i have to change everything else aprt from RAM and hardrive? Is it really complicated to change the processor? If so can you give a diagram or anything, or try to explain how? So basically im looking to firstly get new memory (RAM) to put in whichever you lot choose is the bet comp at the moment, and a new harddrive. Then im gonna get a p4 or athalon processor for that comp, if i can afford it wen you tell me how much they are. Then im gonna install windows xp on it, cause i detest W2k!! Sorry this is a really unorganised and impossible post, please just try oyur best to help! EDIT: Crap i jsut saw the sticky called computer bulding, but still, i think this is a bit to complivated to put in one thread dedicated to alot of people. Billy.
