Hi folks, I replaced my AMD 7970 with a nVidia GTX 770 mainly because with nVidia I always got faster video conversion speeds (my previous card was a GTX560).

I uninstalled the AMD drivers completely and later cleaned it up using DDU (Display Driver Uninstaller), then I did a fresh install of nVidia drivers.

All video conversion apps that I've tried so far can't detect the nVidia GTX card and say that CUDA is NOT available.

I'm trying to avoid re-installing Windows due to the amount of apps that I will need to re-install and reconfigure and wondered if any of you guys could give me a hint on it.

Does your motherboard have integrated graphics? If so, try pulling the card and running driver uninstaller again. Run it for NVidia and then when done run it again for AMD, with no cards installed, IF you have an onboard adapter. Then slap the card back in and reinstall the drivers.

You might also want to try installing the drivers from the card manufacturer instead of the NVidia website or visa versa if all else fails. Sometimes the OEM has a slightly different driver version or a driver that's been tweaked.

Hi there, I figured out the problem, the latest nvidia drivers broke CUDA support on many apps, I installed an older version (337.88) and acceleration got detected on all apps now.

Solved, thanks!
