Thanks for your responses guys, I found out what kind of RAM I need. I need "DDR PC3200", I'm going to buy it from Crucial. My uncle told me to go there and check my PC with the scan and then buy from there. He says that they don't send you bogus stuff and they're reliable and that he's been using them for a while, so I'll buy it from there, seeing as my uncle makes and puts together PCs for a living, lol.
