It generally happens when i'm playing a game, mainly age of empires 3, but after playing for about 30 minutes it will close and say there is an error and so i lose all the progress i've made since saving. I tried about a week ago to reinstall xp professional but that didn't solve the problem so now i have no clue what do to because i don't even know where to start to solve this. Any help you guys can offer would be amazing.
