So I am using a GTX 650, got it about a year ago. Today I was just playing a game in the main screen, then randomly in the middle of play, the 2nd screen goes dark. I closed the game and (I had the screens expanded not duplicated) tried to move my mouse over there and click to see if it comes back (which I never had to do before, normally as long as the main screen is on, so is the 2nd). The power button is still green like it is getting signal, but it is black. If I turn the monitor off then back on, the screen works correctly for about 5 seconds before going dark again. (the power button is still green, not orange like sleep mode). I don't know what they are specifically called, but the 2nd monitor uses a blue ended cord while the main uses a white. I checked all connections to the monitor and PC and nothing changed, restarted the system to no avail too. It still shows up in device list and windows says it is working properly.
It is bugging me as I use the 2nd screen a lot and its making me worry that my graphics card may be dying, but its only a year old and has never been overclocked. any help would be appreciated.
