I have a Compaq 7000z series computer that must be about 4 years old. it has a 1.1 GHz athalon processor and 256 mb pc133 RAM. this setup is getting quite slow with games and an almost full hard drive. I'm a broke kid, and my mom says itll be at least a year before she'll pay for a new computer, but says that she'll pay $200 for ugrades on our old one. I have been thinking about getting an extra RAM card but dont know a whole lot about inner computer workings. my question is, would more RAM be the best way to speed up the computer, and can i use a DDR ram card with my current pc133 card? also, would i need any other hardware such as cooling to support a new card? any advice on what would be a better upgrade or what would be a good card to buy would be appreciated.
