Blender stuck in Cycles render I am new to Blender. My model doesn't have subsurf modifier or any materials. In Blender Render my model renders properly, but in Cycles Render blender stuck. I have no idea why this is happening.

My model link: https://drive.google.com/open?id=1ucDpaQ2jrebaJRdSSQLY0wbUsF11_Yi9
This is what I get from your file, cycles render, after a few seconds.

Maybe some driver/graphic card problem?

Hope it can help your troubleshooting.
