Also on the drivers page there was not anything for Vista.....
The A60 series is very old… it looks like only Win XP was supported… the new systems like Vista or Win 7 are not officially supported and therefore the Vista/Win 7 drivers are not available for this series.
In such case you will need to search the display driver at your own hand.
I think your notebook supports an ATI graphic card but I’m not quite sure what is the name of this GPU card.
Therefore could install some hardware diagnostic parts like Everest Home Edit or SANDRA soft to get details about your GPU chip.
But also DXDIAG should contain the graphic chip name.
Having the details of your GPU, you could search for Vista driver.
