External Monitor goes black using mini-display port to dvi cable

I am exeriencing an issue with my new MacBook Pro(summer 2012). When connected to an external monitor, using the mini display port to DVI cable, after a period of time all of a sudden my screen will flicker and go to black. Sometimes I just get a screen of snow. I have to then power down the Macbook, disconnect the mini diplay port, boot the Macbook back up and then plug the mini diplay port back into the laptop. It may work for a while then the issue happens again.


I called Apple and they recommend I take it into an Apple store. Problem is an Apple store is 2 hours away and I am not sure they will be able to replicate the problem, since it doesn't happen right away. I know it's not a monitor issue, since I have switched out the monitors and the issue still occurs. I have reformated the HDD many times. Still not sure what is causing the issue. Any thoughts?
