Hey guys,

When I render it the screen stays black and remains black until it's finished.

When I set the viewport shading to rendered, it seems to work fine but stops usually around the 8 second mark. And the black and grey checkers remain.

I'm trying to render using the Cycles Render.
The compute device is set to "CUDA" and my graphics card is a Geforce GTX 670.

Under the render tab the settings are as follows:
Display: Image editor
Feature Set: Supported (have tried experimental, too)
Device: GPU Compute.

I also have the latest Nvidia drivers for my card installed. I also installed the CUDA driver for my card, but nothing helps.

Please, if you have any ideas on what could be causing this please let me know.

Thank-you,
Jack
