pc gaming, black screen, crashing, driver failure?

My computer is pretty decent. an fx-850 8core/4gh, r280x and 10gb ram. here's the issue. I'll be playing a game and it will crash. screen goes black, resolution is refreshed, audio remains. sometimes I get a message "your video driver has crashed and has recovered". firs thing you should know is that some of my games don't do this at all such as darksouls 2. shadow of mordor usually does this over an hour into. Lords of the fallen usually takes half an hour but it just happened within 10 minutes. Here's the tricky part. Alien isolation did it as well but after turning down the graphics it does not do it at all. So I figure this solution could work for other games as well. no luck. Two great examples are the greenlit games "no more room in hell" and "the fifth day". both of these titles are pretty low end in graphics, but they are unplayable due to this problem. the second game never crashes however it just continues to turn black and than it actually recovers only to go black again. So in essence the problem is very complex. I have tried altering settings in AMD catalyst manager with no luck. I than did a complete reinstalled of my system and installed all of the updates available. I also tried other drivers for my card. I thought perhaps the system is overheating but that was not the case at all. Any ideas at all. please,
