This may sound really stupid, but I dont know if im having a mother board problem or a problem that is in the system. Here is the problem, whenever I am on for more than 20 minutes or in a game such as cs,RO,MOH, my computer shuts off. After it shuts off i can't turn it back on for 10 minutes. I thought my computer was over heating so i took off the panels of my case to let more heat out, but it still shuts off. I dont know what the problem is and i can't do my term paper with this interference. Please can some one HELP!
