Reload Asus hybrid graphics driver

Does anyone know how to reload the nVidia hybrid graphics driver for a UL80Vt laptop. I contacted Asus and they instructed me to reinstall the driver, reboot and resave the default bios. I loaded the driver from the CD that came with the pc, rebooted, entered the bios, set the default and saved. However, Windows 7 64 still reports that it cannot load the driver (code 31). This means that I am left with using the Intel graphics driver. Any help resolving this would be greatly appreciated.

I've since tried to install the nVidia driver in safe mode. After booting, the nVidia driver is not active and I get the following when checking its status in device manager:

I could really use some help on this as ASUS has such terrible support.

 

Bump....Looking for help on reloading nVidia hybrid graphics driver.

 

Maybe you can try:

ASUSTeK Computer Inc. -Support- Drivers and Download UL80VT
Here is a Hybrid Forceware 186.88 driver under Windows 7 64bit. Probably the same that's on your CD.

Go to Device Manager, expand "Display adapters" and right-click each device and click 'Uninstall' and tick 'Delete the driver software for this device'.

Restart when asked, and do it for both video cards.

After that, go back there and right-click and click 'Update driver software', then click 'Browse my computer for driver software', 'Let me pick...' and now click 'Standard VGA Graphics Adapter'.

Do this for both graphics cards and restart if asked.

At this time, in Device Manager, both graphics cards should be called 'Standard VGA Graphics Adapter'.

Now, try install the driver.

 

namaiki... Thanks for the quick response. One question though. I took a look at Display Adapters in Device Manager and noticed something very strange. The only adapter showing is for the onboard Intel graphics. But, the driver details show it with the date and version of the nVidia driver. Do I need to reinstall the onboard graphics also? Will the procedure you've outlined handle that?

 

After you uninstall the Intel graphics driver and restart, the other graphics adapter should hopefully appear.

 

namaiki...I followed the procedure you outlined. I was able to remove and reinstall the nVidia drivers. However, once I reboot, I get the same status I've been getting for a while now.

This is driving me absolutely nuts. Do you think this may be a hardware failure? I'm still running with the original BIOS. Could that be the problem?

 

Can anyone else help on this? The last attempt involved using namaiki's advice and the VGA patch from the ASUS web site. It's my understanding that the VGA patch is used to remove prior registry entries when the graphics drivers are removed. Using this tool did not help. I'm still stuck with the Intel graphics adapter. Windows will either complain about the nVidia adapter (code 31), or, not see it at all.
