I have a Nvidia Geforce4 420 Go 32m (a 32 mb grapics card for my laptop). It says the detonator version is: 47.12, but isn't there a 61.77 version released at nvidia.com? If so... I'm asking on how I can upgrade my graphics card driver to the newest one. And also... can my graphics card be updated (I've heard my card is a little different... probably because its from the "Go" series for laptops). Thanks in advance!
