Chris, Here is what I have done (prior to receiving your most recent email) ... I tried upgrading the nvidia drivers but could not because I had a very old card. I purchased a newer one (GeForce GTX 660), installed it, rebooted, upgraded the nvidia drivers to 346.96, rebooted and found the problem to be gone. Is there anything else you would like me to run at this point that might be helpful?
