Correct process for switching graphics cards

Recommended Posts

I currently have a 2GB Nvidia GeForce GTX 770 GPU installed in my PC. However, God decided this weekend that it was time for an upgrade, and so I am now in the possession of a very nice 6GB GeForce GTX 980Ti :cool: That being the case, I would like to know the correct procedure to replace my old card with the new one. I suspect that I need to do the following....

  • Download the latest set of Nvidia graphics drivers
  • Uninstall my current graphics drivers
  • Shutdown the PC
  • Remove the old GTX 770 card
  • Fit the new GTX 980Ti card
  • Reboot the PC (in safe mode?) so that the OS detects the new card
  • Install the new graphics drivers

Is that correct? I fso, do I need to uninstall the old graphics drivers with that DDU (Display Driver Uninstall) utility?

Hi Christopher,

Looks good to me. I would use DDU to uninstall the old drivers. Don't think you'll need safe mode.

Remember too that Prepar3d.cfg has graphics entries so renaming that and letting P3D generate a new one would be advisable.

Enjoy your new card. 👍

Yes, you really should use DDU in Safe Mode to clean everything related to your 770.  Safe Mode insures all the registry entries for the old card are deleted.  DDU in Safe Mode really does a great job cleaning the registry!

  • Make sure you have the 980Ti's manufacturer's drivers.  They should be installed after you first install the new GPU.  Then, if you wish, you can clean the manufacturer's drivers and install an appropriate version of nVidia's drivers.
  • DDU has an option to clean the old drivers in Safe Mode and then shut the computer down so the new GPU can be installed.  Easy peasy!

No need to reboot the computer in Safe Mode for the first boot with the new GPU.  Definitely disconnect the computer from the Internet... MS loves making our driver choices for us when they are allowed. :laugh:  Install the GPU manufacturer's drivers, then reboot, and then tweak the driver settings using nVidia Control Panel or nVidiaProfileInspector.

Have fun!

Greg

I have Windows 7 at the moment, so I do not need to worry. As for the drivers for the 980Ti, I will be installing the latest Nvidia drivers from the website. I do not have the DVD that came with the card, but I am reasonably certain that installing those specific drivers is not required.

On a side note, I am now intending to upgrade most of my PC at the same time. I had a fair bit of luck over the Cosford weekend, and I want to take advantage of the situation :wink:
