If you are trying to enable GPU assisted Ray-traced rendering then you have to install an NVIDIA card that is on the supported list install CUDA and check the box in the preferences that says Enable Unsupported GPU. You must have the latest build of AE installed to have that option in preferences.
Adobe as announced that they are no longer developing for CUDA acceleration in After Effects and the integration of C4D in the latest builds makes this a mute point anyway.
