How to install new drivers/delete old driver remnants

Without modded inf: (the driver lists your graphic card as a supported model)

Download the correct driver for your OS (XP/Vista/7, 32bit/64bit).

1. Uninstall your current driver through the control panel. (http://img42.imageshack.us/img42/2499/nvidiauninstall1d.gif and http://img195.imageshack.us/img195/8803/nvidiauninstall2.gif)
2. Restart and boot into safe mode (F8). (http://www.computerhope.com/issues/chsafe.htm)
3. Run Driver Sweeper and maybe even CCleaner. (http://www.guru3d.com/news/guru3d-driver-sweeper-205--released/ and http://www.ccleaner.com/)
4. Restart and boot to the regular desktop.
5. Install the new driver.
6. Restart.




With modded inf: (the driver does not list your graphic card as a supported model)

Download both the driver and the modded inf for your OS (XP/Vista/7, 32bit/64bit).
(Modded infs can be found here: http://forums.laptopvideo2go.com/forum/123-nvidia-drivers-and-tools/)

5. Decompress the downloaded driver and copy the modded inf into that folder.
6. Run the setup.exe you can find in that folder.
7. Restart.



Alternatively you could just install the new driver on top of the old one, but in rare cases this can cause problems because of old driver remnants.

In case you're getting an error message when you try to install the driver, decompress it with a free tool like 7-Zip (http://www.7-zip.org/), move the PhsyX and 3D Vision installers from the folder and just start the setup.exe in the decompressed driver folder. After the driver installation finished you can install PhysX and/or 3DVision without a problem. PhysX installations are incremental, meaning that you can just install the new version on top of the old one.

Also: should you not be able to get any temperature readings with the 19x.xx driver series use this fix posted by Unwinder:

In case you want to thoroughly get rid of previous driver remnants and Windows 7 keeps installing a previous driver version try this guide posted by Squall Leonhart:
