Older models than yours have a history of failures of the discrete graphics chip. Your model does not.

If this is a one-off problem, ignore it. If it is getting to be a serious problem, you could replace the mainboard.

You could also use the older hobbyist hacks to disable the Discrete GPU entirely. This eliminates the ability to use an external display, and limits high-powered graphics to the Integrated graphics chip only.
