I have tried a bunch of different ones, but they have ads and things that interrupt it; and you have to pay to get the version without them. I have seen computers that come with an aquarium screen saver, same version as mine, but mine doesn't have one. So where can I get a free one without ads? I have tried Freeze.com and Screensavers.com and those free versions have ads. I have windows X.P! And it's NOT there!
