sorry :crying:I'm going to start charging per tech post here. 2002 is I think the service pack date. If you added more memory into it, then it should be reflected already. If you have an external hard drive, your main drives are usually labeled C (C drive.) If you have an external HD hooked up, you can open it up and it's usually labeled E or sometimes even F depending on how many things you have hooked up to the computer. If right click on the letter (like C) it will show you how much memory you used or is free.
Windows XP 2002 means the version/edition you have most likely. So it is possible that you bought that computer in 2002 but its also possible to have bought a computer yesterday with WinXP 2002 installed.
so with that info the conclusion is ....My computer IS old?!!!??
