Well, it depends on what would you like to do on your PC. How much RAM do you have inside? If you're 'round 64 MB, try Damn Small Linux (www.damnsmalllinux.org
). It is a lightweight distro with amazing performance and you have the applications for your common daily needs - word processor, spreadsheet, PDF viewer, web browser, e-mail client and so on. There are also some "light" distros, like Puppy or Vector for example.
