radeon 9550 problems and sims 2

[nandy]

hi i'm new here, i recently purchased the sims2 ( 4 discs) and i installed it, i also installed the no cd crack which enables me to run the game without cd, the problem is when i run the game it would bring me as far as the tutorial ( the man standing in the room) and a blue screen will show and the computer reboots, i installed the latest drivers but i keep getting this vpu recover message and it says something about not obeying driver commands.

PLEASE SOMEONE HELP ME!!!!!!!!!!!!!!!!!
