Is it possible to upgrade the drivers? The NVIDIA drivers are at Forceware 81.98, whereas my laptop's Forceware is at 78.51. I tried uninstalling the drivers that came with my laptop, then installing the GeForce drivers (from the NVIDIA website) for Windows XP, but it said that it couldn't find any hardware that supports the drivers. The only other drivers I can find for the GO series is the 7800... So... is it possible to upgrade my video card? Thanks.
