Crashes during Salome

During installation of Caelinux, I use the guided option, it erases the entire disk, so I do not know whether a swap partition is installed or not. Second, I have 4GB of Ram in my desktop computer, so I think that is fairly enough. Currently I am not in my own town, in the weekend I will reinstall Caelinux and hopefully with a swap partition. Anyway, thanks for the replies.
