My PC shuts down when I close GW.

When it boots back up, it tells me that it has recovered from a serious error. When I send an error report, it gives me this:

How can I fix this?

try going to nvidia.com and upgrading to the 77.77 drivers. If these don't fix your problem you can also try installing the 71.89 which were the last good drivers prior to the 77.77's.
