Why does my computer freeze up when updating the preview window in cycles with gpu compute? Whenever I update a material with the rendered preview window open my entire computer freezes up and requires a reboot. This only occurs in cycles when using gpu compute. I have linked to a video showing how this occurs only with gpu compute. I can also link to the .blend is necessary.

Thanks for any help or ideas!

After further research I have found that amd gps are not completely compatible with blender cycles, could this be the reason for the crash?

Go to the User preference and check for 2 things.


Is the correct Graphics card listed in the Compute Device section?
Is CUDA enabled or if your GPU actually support CUDA?


UPDATED ANSWER
Yes there is a limitation on the support for AMD GPU unfortunately, at the
moment it's pro nvidia. Feb 2016.
