Dell INF & NVidia Driver?

Complete shot in the dark here.

My dell 9400 laptop with Nvidia 7800 gets really hot when I manually install driver 91.31 using the nvidia download and laptopvideo2go inf. When I roll back to my old dell 78.59 driver the fan kicks in big time and cools the GPU down. Is it remotely feasible to use the 78.59 inf file from the dell driver download with nvidia 91.31? I'm guessing the settings in that inf would more accurately represent my setup. I guess some adaptation would be required of course. But would it be a complete rewrite or just some minor alterations?

AFAIR Dell released a 84.xx driver for your graphic card... use it. It's the best driver you could get for your laptop.

The 91.3x only add some SLI features and some extra PureVideo filtering enhacement. Since I doubt you need either of those... stick with Dell official driver.

Yeah, thanks for that. I was looking at

http://support.dell.com/support/downloads/...=WW1&osl=EN

the website for my dell drivers. I went to video adapter tab and opened both nvidia graphics tabs 7800 & 7900 GS. If you go and look, the 7800 driver is v.78.59 & the 7900 GS is v.84.69. But if you look in the inf file for the 7900 GS driver, at the bottom it supports the Go 7800. That should be the driver for first link.

Another thing I noticed the inf files here use NVIDIA_G70.DEV_0098.1 = "NVIDIA GeForce Go 7800 " while Dell use NVIDIA_G70.DEV_0098.2 = "NVIDIA GeForce Go 7800". The end of the first string the .1 and the .2, I have no idea what they mean. But I was wondering why dell would be different?

1 and 2 are different SUBSYS_IDs for each DEV_ID... which may even need different INF settings for example one may need AddReg = AdaptiveClkEnable_AddReg and the other one _NOT_.
