nVidia 9300M GS Win7 x64 drivers for the VGN-z540?

Hello,

Has anyone installed Windows 7 x 64 on your VGN-z540 laptop? I tried nvidia's web site, guru3d, sony etc. but I can't can't find drivers that Windows 7 will accept on my 540 laptop. Every other piece of hardware works including the intel video it natively detected. I can't seem to get it to recognize the nvidia driver. The driver won't install from setup. I can manually try to force it by selecting the device, update drivers, select manually but it says it wasn't the right driver even though it is the 64 bit driver for nvidia and it has the 9300m GS listed many many times in the list.

THanks - it looks like that is a step in the right direction but I still have something wrong on my laptop. After installing that and rebooting, I have an exclamation point in device manager next to both my intel onboard and nvidia driver. If I disable my nvidia and reboot my intel works correctly. If I disable my intel and enable my nvidia and reboot, I have the exclamation point still my display is messed up as it uses a generic driver.

 

What is your bios version?

 

I downloaded the latest one from Sony - http://esupport.sony.com/US/perl/swu-download.pl?mdl=VGNZ540&upd_id=5268&os_id=49 it ran fine. It says my bios is current.

Maybe it is because my stamina / speed switch probably isn't functional along with my other function keys for sound, video etc.

 

You probably need R4044M3 BIOS.
