It all started about a month ago. I own an EVGA GTX 660 Ti Superclocked Edition with an Intel i7 2600 processor. GPU-Z used to always detect OpenCL, CUDA, and PhysX. and all of a sudden it stopped. I first became aware of the issue after I decided to play Arkham City one day after a long time and it said it couldn't detect PhysX...I've tried testers and all say my hardware is incapable. I would do a System Restore if I could, but the last one indicates over a year ago. ->If anybody has faced this issue, and knows how to solve it, please let me know. Or, if anybody has any idea that may or may not work, please let me know. It would be appreciated. Solutions I've tried: Trying my card in another computer (it worked fine) Reseating Graphics Card in PCI-E slot Trying previous versions of NVIDIA driver ->Uninstalling using REVO, Driversweeper, and manually. Trying BETA drivers Disable Intel HD Graphics from BIOS Trying to install CUDA SDK (couldn't detect CUDA) Chatting with at least 20 NVIDIA agents which led me nowhere When I click Intel HD Graphics under drop down, all of them (Computing options) are unchecked (even DirectCompute 5.0) which is weird too.
