I’m new at CUDA and am stuck at the install stage. I’m using Windows 7, and have an NVIDIA GEFORCE GT 540 M for a notebook, and I installed the CUDA drivers for that (along with the GPU computing SDK, CUDA toolkit, etc). To verify everything, I went to the
C:\ProgramData\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.0\C\bin\win64\Release
and I ran bandwidthTest.exe, to see if it would work.
So here’s the fun part. When I install and update the drivers and immediately navigate to that folder and run the file, the test passes. But if I then fudge around and try running a few other files (maybe some not compatible with my particular GPU) I get the message: no CUDA capable device is detected. Then after that point, EVERY TIME I try to run bandwidthTest.exe, I get that message (no CUDA capable device is detected). This is pretty much irreversible unless I reinstall the divers and do a clean install.
Is anyone else having this issue? Is there a fix? Or maybe a general reset-to-factory-settings switch? It would be nice not to have to reinstall the drivers every time I make a mistake. Thanks!
