Combat Arms keeps crashing when I play?

When I play Combat Arms it starts up fine and I can go through the menus fine but when I enter a game it will play for a little bit but then it was freeze, a blue screen comes up with words on it (it goes away too fast for me to read it) and then it reboots as if I restarted my computer but the laptop doesn't shut off. What's wrong? Please help I love Combat Arms and want to be able to play!
