Nvidia control panel not working.

I just replaced my 7800GTX with an 8800GTS, and have tried the 158.22 and 162.18 drivers.

When I have ntune installed, the control panel opens but it only shows the performance and stability groups, and does not show the manage 3D settings or TV and Video groups.

When ntune is not installed, the control panel does not open at all.

I used driver cleaner to remove my old drivers, and tried two different drivers and it still doesn't work.

The NVidia settings icon appears in the taskbar, and can be used to change some basic settings, but it doesn't seem to be working correctly either. For example, it doesn't show all of the antialiasing options.

Any ideas about what I'm doing wrong or how to fix it?

I uninstalled the drivers again and installed using the cd that came with the card. (it installed 158.22)

Now I can open the nv control panel, but it is completely blank.

When I install off of the cd, it adds some extra tabs to the Windows display properties. They are for information, adjusting the clock speed of the card and a few other things, but there are no 3D settings. Since it adds tabs here does it not work with nv control panel?

It also installed some kind of Dynamic Overclocking Technology, which my antimalware software says is a virus.

There was a post on nV forums that suggested that the installer does not register certain DLLs. I don't have time to find the link right now, and although I have the same problem, it didn't bother me enough yet to try out the suggested solution. But if you find it and try it, please do let us know.

This is a problem I have on my computer as well since installing a 8800 GTS. Ntune, etc all result in hard lockups. I uninstalled all of it and now use RivaTuner. In the Nvidia release notes, there are a bunch of problems listed with the 8800 series cards which Nvidia has yet to address. The 7800 GTX which I used to have didn't cause any problems, so I think its something to do with the 8800 series in particular

I have similar problems with the control panel that nrn9520 has. If the control panel does open without locking the computer, the adjustment lines and 3D settings are grayed out, stating that i need to install Ntune, etc. But if I do that, then its back to hard lockups. Nvidia really needs to fix this.

To anyone with parts missing make sure you go under adavaced view and check all the boxes you want.

Mine had it all right off the bat....but crashes with some game profiles. if i select COH(city of heroes. the cp crashes every time...so i cant change settings. but the in game settings are ok)

I saw you on a different thread looking for an answer. I struggled some more with my Nvidia cards, seeing that both my and my son's computers use them. I finally have decided that the problem is with Nvidia. Whether its specifically the drivers or a problem in the cards themselves which they haven't fixed, I don't know. I have noted that both my son and I have AMD K8 CPUs and the Nvidia release notes say that there are specific problems with AMD K8 CPUs. For that reason, I'm hoping that ATI comes out with a very good card when I upgrade, as I'm getting tired of the Nvidia battle. Never had these problems with my old X1900 XTX card.

Yeah right, "What is the meaning of life?" if I ever find out, I'll write a book and make a lot of money. That question is right up there with trying to understand a woman, which can't be done.
