I have windowq vista business 32 bits and a graphics card "Mobile Intel 4 Series Express Chipset Family".
Its driver was released the september 2008, so I want to upgrade it thanks to the intel website (http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&ProductFamily=Graphics&ProductLine=Laptop+graphics+controllers&ProductProduct=Mobile+Intel%c2%ae+4+Series+Express+Chipset+Family).
I tried the two last drivers but I received a message "The driver is not validated for this computer" and the installation stops.
Somebody has an idea???
