Being a five year old PC, you may wanna check the specs on the cpu it has, most likely its a pentium you can upgrade it to a faster one (check the type of socket the mainboard has to determine which one is right for you). I bought my dell pc in the early part of 2002. It has a Pentium 4 2ghz. I'm thinking about upgrading it to a faster processor,with more cache etc. You can also drop in a few exta MB of RAM in there. 4BG's the limit. If you're into gaming you might want to upgrade you Video Card also (dont forget the RAM). There are prolly other little tweaks you can do to spice up things a little. Good luck.
