Dual monitor setup - both monitors randomly go blank, come on again and freeze.

I run arch linux with dual monitor setup. Just day ago I started to have issues with my monitors. They would turn blank, not power off, and display ‘no connection’ message and come back on again. They would do this several times and then freeze. The system isnt frozen, only the monitors because sound still works fine. I tried updating drivers but that didn’t help. I have no idea what could be causing this issue.

Here is the nvidia bug logger log: http://pastebin.com/ShDt1fWU
