Anyone ever have this display problem? Monitors go black/restart every 5 seconds.

Not sure what's going on! PC was running fine last night. Today, the monitors restart on me every 5 seconds. They go black and turn right on again. Rinse and repeat.

It looks like the monitors are stuck at a refresh rate of 60 or else I would change. I reinstalled GPU/monitor drivers. That did not help. I do use an older video card - a GTX 650 boost. I was told to turn off G-sync. I haven't tried that yet. Any advice would be awesome. Thx in advance.
