There is a tendancy of creating Nvidia cards that aren’t directly supported by Nvidia an example of this is the Quadro FX 1500m on the Dell Precision M90 ( 2007 era ) which I believe is also available on some HP high end laptops. These cards were high performance but a bit buggy. I have seen two of the Quadro FX 2500m cards on different Precision M90 fail I believe because of heat issues. Previously I have only been able to use Dell drivers on the M90 but Dell doesn’t offer any drivers for Windows 7 on these cards.
The GPU used in these cards is the G71GLM which is also used in the Geforce Go 7900 GS, there are a set of BETA drivers available for the Geforce for Windows 7, once the initial executable ( 197.48 ) extracts its files you can edit ( default path ) C:\NVIDIA\WinVista64\IS\Display\nvdm.inf on line 136 from
