I've searched through the forums and haven't found a problem similar to mine. Every minute or so on the far right hand side of my monitor a black line that's about an inch wide and goes from the top of my monitor down to the bottom flickers in and out for about 2-3 seconds. I've tried everything from switching the resolution between my three choices and lowering the graphics but nothing has worked so far. I'm using the Nvidia Geforce 560 TI (not sure if that matters.)
Anyone have any ideas on what I can do to stop this? It isn't game breaking but it sure gets annoying after 30 minutes or so of it happening.

I take it no one knows how to solve this problem?
