A solution to this issue has been discovered. First I forgot to include the existence of a third hard drive 500 GB SATA HDD that once unplugged from the system no longer causes the system from rebooting. The power supply (P/S) is a 680 Watt so I would think it would be able to handle it. I have been running the game just fine for a few weeks now with no issues since then.
