i bought a new pc last week, i3, 4 gb ram 1tb harddisk, 2gb nvidia gtx 650 ti. when i play battlefield 3 and some other games runs smooth on high/ultra but sometimes the games crash. i can't understand what's causing this problem. i updated the graphic drivers, have direct x 11 installed, can't think of anything else that could cause this problem. i have another pc and it has gtx 620 on it battelfeild 3 has never crashed even on high with lower fps. plz help
