If you run Bminer and get an error saying “Failed to initialize the CUDA platform: CudaError: Could not initialize the NVML library” then there is nothing wrong with your mining hardware, the problem is in the Bminer. The reason is that newer Nvidia GPU drivers have moved the nvml.dll library that the miner uses into a new location and Bminer is looking for the NVML dynamic link library in a specific location, so even if you copy the DLL file in the same folder where the miner is it will still not work. If you are using newer Nvidia drivers you will have to copy the “nvml.dll” file from the “\Windows\System32\” folder to “\Program Files\NVIDIA Corporation\NVSMI\” and have in mind that you need to create the NVSMI folder there as it will not exist and then copy the DLL. Running Bminer after copying the library (do not move the file, or other programs might stop working properly, just copy it!) to the specified folder should eliminate the error message and the miner should start normally again.
