I just bought DDR1 512mb Ram, plus the existing 256mb Ram, so total is 767mb Ram. My laptop is Celeron 1.40mhz speed of processor, do you the specification like this can run Windows Vista smoothly? After I have tried, I think so far so good. I cannot say it perform very prefect but acceptable, this only I install the Home Basic package instead ultimate version ones.
Windows Vista is good but it can hog your CPU and Memory.*`-
