so basicly as the tile says. im playing the game and then all of a suden it goes to a black scream with "receving". i cant do anything. cant exit ect ect. i have to end the prosses. comp specs are: core 2 duo E6850@3.00 GHZ( i know its not the best.) 2GB ram with a GeForce 8800GTS. i have no computer knowlage. just like to play games to kill my time up at camp. is it just my comp shitting out? what would i have to upgrade( on a buget, all my spair money goes into building my race truck)
