Reading through the forums, I know that this has come up on multiple occasions but I am not sure how to troubleshoot. I have windows 7, nvidia graphics card (660 Ti) with current drivers (347.88) and still receive this error. I appended the log below. Thanks in advance for whatever advice you can offer.
