Just recently my computer has been "blacking out", the sound is still running though. Every time that it happens (three times one) the two screens that are connected to the GTX 980ti go black. I have to hit the power button to turn the computer off and back on. The first time I had to reinstall the gpu driver because it was in black and wight. The two most recent times I have just had to restart the computer. I have no idea what the problem is. I have already tried swamping power supply but that has not fixed it.
