Well I just did everything that Star69 suggested. I only ran the stress test for about 15 minutes because I do not have time to do more right now but I will try again later. I did check all the connections inside my tower to make sure they are set up correctly. I don't think my power supply is too weak. It is a EVGA 750 GQ, 80+ GOLD 750W. So unless it is faulty or it's age (4 years) has degraded it that should not be the problem. However the other question is if that is the case why is it only when playing this game does this problem happen? I have crash in any other game or activity.
