download 169.28 that seems to be working best for the other users. after extracting the file replace the original inf in the extracted folder with the inf you downloaded from this site. Then install

The 169.28 version drivers are not good for this video card! I tried them because I have the same laptop and video card as the poster of this topic! I have tried allot version already and none seem to work properly! If someone can be so kind to help us with this, then I would be most gratefull.

I have been using the following driver versions on an Aspire 7520G (8400M G):

- 156.83 (indicated on this site as latest 32bit XP driver)

- 169.04 + inf (28/10/2007

- 169.09 + inf (12/11/2007

- 169.21 + inf

I did not try 64bit version of XP as some of the Apps I use have issues with this (also the reason why I downgraded to XP from Vista.

simply remove any nvidia driver first (!)

reboot, and install the drivers from this awesome site (replacing the inf file before starting the install ofcourse)

3DMark05 results (default settings after driver install - no overclocking):

- 169.09 = 1611

- 169.04 = 1610

- 169.04 = 2058 (overclocking 500/500)

- 156.83 = 1957 (!)

it appears that the 156.83 is the driver which works best on my configuration - this could be different for yours ofcourse.

hardware: Acer Aspire 7520G - 2Gb - 2x160Gb - 8400M G 512Mb (reported by nVidia Config)

I have a huge problem with my brand new Samsung 305T (30") though - but will make a separate post on it..

Just go back to Vista if XP is giving so much trouble. It is more responsive and looks prettier.
