The game works with no problem some days..when you turn it on the next day and you press the start button it may or may not start.....sometimes you have to use "Task manager" to stop the game..sometimes that may not even work and you have to turn off the computer.
The current problem is even with graphics at lowest possible settings you can race without a problem until the game is about to go to the podium scene...then it crashes.
Please find "Dxdiag file" attached.
