As titled, I have just installed Windows 7 Pro SP1 (64bit) on my laptop and is having issue with the nvidia graphic adapter..
This laptop (Lenovo Y460) comes with Intel HD Graphic as well as Nvidia GT 425M.

The error code 43 appears on the Nvidia GT 425M when I installed both the graphics drivers.

This is the hardware id for the Nvidia 425M
PCI\VEN_10DE&DEV_0DE0&SUBSYS_396C17AA&REV_A1
PCI\VEN_10DE&DEV_0DE0&SUBSYS_396C17AA
PCI\VEN_10DE&DEV_0DE0&CC_030000
PCI\VEN_10DE&DEV_0DE0&CC_0300

Any advice?
