I have a GTS 250 so I would junk the lot and download "310.70-desktop-win8-Windows 7-winvista-32bit-english-whql.exe" from Nvidia's website. This is the only file you'll need. I'm using 64bit but I'm sure 32bit will be the same if not let us know. Yes I junked the lot except for the control panel, and installed the driver you referred to. It offers to install Physx, and 2 other 3d drivers which I didnt do, so all ive got is control panel and 1 driver. Cant fault it
It's a lot smaller than all those packages what site is that pic from? That screenshot was from Revo Uninstaller
When you run it it will extract to a temp folder that can be deleted after installation or left for quicker reinstall if ever required. Yes I deleted the file it extracted to, but Ive got the downloaded driver file if needed.
After extraction it should automatically run the setup.exe file if not it can be found in "C:\NVIDIA\DisplayDriver\310.70\Win8_WinVista_Win7_32\English" or similar unless you changed the extraction path which it would be in your chosen folder. Yes thats where it extracted to before install
Agree and Continue on the License Agreement then if you choose Custom Install you will be listed with items similar to the pic in your opening post except the versions. Every version in your pic is outdated and all the programs/drivers are included in this one package. Dont you just love Windows update?
Checkmark the Graphic driver obviously
I would recommend the PhysX System Software ok ill reinstall and add it
Nvidia update is up to you. I did find this hard to remove once during an update and have not installed it since as I don't game and check for updates when I can be bothered. no dont like that update stuff running, ill choose when to update.
The 2 3D components are optional they are for use with 3D gaming. no, no gaming
The Nvidia Control Panel is not listed but will be installed and gives you access to change a range of settings for your graphics.
