OK, this is really starting to get on my nerves. As the title says, recently, FSX started shutting down after a period of time. I have done some research on the mater but have not been able to find a solution. I have a brand new video card so I do not think that is causing the problem. I have checked the temps and they seem to be within normal parameters, so if anyone has had the same problem and knows of a fix please let me know. Any and all ideas will be greatfully accepted.
