Whenever I try to open any games either a) the game quits and says there was a fatal error in your graphics driver (this does not happen much after updating drivers), or b) the monitor sleeps, and when I turn it on, it says no signal, so I have to completely restart my PC. It is not the monitor or the connecting cable, because it works completely fine when I am not playing games. I'm wondering if it has something to do with the graphics card and its output? (my video card is a Radeon R9 200 series, as mentioned above).
