Hey everyone. I have been having problems recently with a newly built computer. I have ran a couple games on it before and i always seem after a good 30 mins of play the screen freezes and the computer locks up. I can't Ctrl + Alt +Del or anything except reset the computer. I am posting this in hopes of receiving some feedback on some troubleshooting tips on how to diagnose this problem. I want to apologize in advance if this has been incorrectly fourmly posted. I am going to post all my comp specs. I have ran a memtest and everything came back fine, I have ran 3Dmark and got a score of 8k. I really dont' know what could be wrong. Any feedback in appreciated.
