Sony Z laptop weird 9300 M driver

hey guys.
i've encounter a really weird problem...

i have a Sony Z555DN laptop
with 9300M GS Video card...
running Win 7 Ult.

downloaded the driver from Sony's website.
install...works perfectly fine, in Device Manager it reconigze it...
after restart the driver is gone.....

in device manager.
under display adapter>
Mobile Intel(R) 4 series Express Chipset Family.

after i install the 9300 driver it will display both drivers.
thats fine,
then i tried disable the intel express
still fine

only everytime i restart my laptop the 9300 is gone,
only shows mobile intel 4


Help, without that driver i cant hook up to HDMI ...
