No, friend 1Gb ram is not enough for running Vista if you don't have a somewhat better graphic card. I have D101GGC which have ATi X200 onboard graphic card. But when i run any movie in VLC player vista will automatically apply basic Aero theme from the AERO and when VLC closed, back to AERO.kirtan said:yes man 1GB is the minimum requirement for the smooth operation of the vista.Even my 512MB RAM could not operate smoothly with the beta version of vista
