I have extra NVidia drivers, after installing AMD Catalyst drivers and changing the GPU.

I got an HD 7850 a while ago, installed the drivers, and forgot to uninstall the NVidia drivers for my old graphics card. I have tried using the programs and features window for uninstalling all the NVidia stuff, but it didn't open any uninstallers. Is there an NVidia driver uninstaller I can download or something? I would love to get rid of these extra drivers, because I want to make sure that I'm using the right drivers for my graphics card.

P.S. The GeForce experience taskbar symbol loads on startup, but I can't open Geforce Experience or the control panel for NVidia. For GeForce Experience it just crashes with an error, and for the control panel it just tells me I don't have an NVidia graphics card.

Thanks so much! I still have NVIDIA PerfHUD 64 bit and NVIDIA PerfSDK, and the NVIDIA Control panel in the control panel, but all the drivers are gone! What's the point of these two things, and can I get rid of them? Programs and Features still isn't letting me do that... I'll just get the Nvidia Physx somehow. I don't think I have any games that use it, but just to be safe I will.

Wait... I have to download an NVidia thing although I have and AMD product? Why do I need Physx? Wouldn't it not work with my AMD graphics card?

You should be able to delete them manually: http://www.overclock.net/t/1150443/how-to-remove-your-nvidia-gpu-drivers

PHYSX - You would NOT be downloading that, or anything from NVidia when using an AMD card. Some games use PhysX via the CPU but that's all part of the game code so not something you need worry about.

UNINSTALL:
The above link might help, but I'd also try INSTALLING the most recent NVidia drivers, check all features, then reboot and go back to uninstall and remove everything you can find. Reboot when prompted.

Having said that, I've never tried to install drivers for a card that isn't installed so it might not work.

Other:
Remove the NVIDIA subfolder on the C-drive (C:\NVidia). This is a backup of any NVidia driver you installed and can take up a lot of space (about 250MB per driver set). I had four sets due to updates and was over 1GB used.

The DDU removes anything Nvidia related, so if he has any game installed that needs to use Physx(software) he will need to download the stand alone version for his games to work properly again. http://www.nvidia.com/object/physx-9.13.1220-driver.html

Here is the issue he could possibly run into once everything nvidia driver related is removed. http://www.overclock.net/t/1292172/solved-physxloader-dll-missing-but-im-using-a-amd-video-card Keep in mind this will happen with any game that was using software Physx after he uses the DDU.

PS: What would be the purpose of installing the Nvidia driver again if he has an AMD in there right now. That could cause more harm than good honestly. The program we recommended is fully backed by the team at Guru3D so it will be fine. The program was designed for instances such as this.
