GP4 CTD problem - im stumped, need help.

Hi all, everytime i play GP4 and try to race in either a practice, qualify or quicklaps session, it CTD.

i have zero idea on whats causing it. any ideas? anyone who had this problem before me?

several problems can cause this.

did you try a reinstall?

i have this wierd problem out of the blue these days where my gp4 or any game just freezes... any idea why?

Please both of you write your PC specs.
