Hi. I was previously running cuda and cublas successfully on my laptop and within the last two weeks but then something went wrong. I am running 64-bit windows 8.1 with an NVIDIA Geforce GT 640M LE GPU. Everything was previously working using Visual Studio 2010 (unsure of the GPU driver installed when working, but I could find out if explained how). Then, yesterday I tried to run a program again for the first time in about 2 weeks and it ultimately boiled down to the no CUDA-capable device detected in deviceQuery.
Here’s what I’ve tried, without any changing behavior(in order):
Uninstall/Reinstall Cuda
Clean Reinstall GPU driver (both newest and second newest drivers)
Tried running Cuda-z but no cuda-capable device detected
Tried all of the above again in varying orders (getting desperate)
Windows System Reset to a week ago (that’s the oldest reset available)
Installed MS VS 2013
Clean Reinstall of GPU driver
I have almost the exact same problems and behaviors as described here: https://devtalk.nvidia.com/default/topic/791925/windows-7-quot-no-cuda-capable-device-is-detected-quot-with-cuda-capable-gpu-installed/
but I really don’t know if I could afford to do a whole reinstall of my OS because it would take at least a few days getting all my software reinstalled and things back to normal…
I haven’t tried to physically remove the graphics card, nor do I even know how to/if I should do that because I’m not that tech savvy with GPUs and I’m 4 weeks new to CUDA.
Please let me know if you have any other suggestions.
Thanks!
Also, here’s an output from running nvidia-smi
