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.

Hi ching1296, have a look at this tutorial http://www.sevenforums.com/tutorials/82137-drivers-turn-off-automatic-driver-installation.html It may solve your problem

When you say uninstall it did you use the nvidia uninstaller or just uninstall it?, also refer to my sig about removing left over files after uninstalling drivers.

 

[ching1206]

no work..
intel graphic auto installs itself...even i choose not to auto install.....
now i have 2 graphic card running both intel n 9300m..

BUT in Screen Resolution only displays "Nvidia Defualt flat panel" not
9300M GS

i cant hook up to hdmi with that graphic card as primary...

 

[ching1206]

nevermind...
9300 is gone after restart.....

OMG...

Are you sure that the primary display driver in the bios is not set to the Intel chipset graphics?

Sony vaio vgn-z555dn

HI
sony vaio has a really good feacture you can run either Intel or Nvidia video card
did you notice the button in the left Conner STAMINA SPEED, if you have pointing in STAMINA will run Intel video card, this is convenience if you want to save battery life, if you run SPEED will use the Nvida card. hope this help you thanks
