First off. If it is completely random, its most likely a driver problem(from the videocard or another video related driver... note some programs have video drivers, especially the ... webcam ones ...)
Next is is happening at a timed interval? Is your windows installation legal and activated?
If all of the previous questions are, No video driver problems, and yes activated. Call Microsoft. Or your 3rd party hardware manufactures.
Otherwise, look to other software solutions(use a live boot cd' and see how long it is stable.)
Also, try using only 10.11 drivers.
