body: <p>I have installed cuda.7.0.28 into my laptop. I tried to run one of the sample file. I ran deviceQuery project and got this message: </p>
  
  <pre><code>cudaGetDeviceCount returned 38
  -&gt; no CUDA-capable device is detected
  Result = FAIL
  </code></pre>
  
  <p>Then, I ran nvidia-smi.exe file and got this message:</p>

  <p>As you see, it is written that "Not Supported". What should I do?</p>
