Intel graphics can be problematic. Be sure to update to the latest available driver and tell us which hardware you have.
Actually you did, and you told us you have a Nvidia GTX 660m (314.22), so do you have two graphics card in this system, and which of your reports refer to which hardware?
Also keep posting error.log (it's small no need to upload it, just put it here in a code tag (hash icon), so its easy to handle, too).
