[QUOTE="tkobvious, post: 1610611, member: 334753"] Well, I hate to say it but I did jump the gun. The computer just stayed on a little longer than usual by chance. Lasted 35 minutes and then the screen went black. Unresponsive like before and had to restart. Fortunately, this Macs Fan Control program has helped me further pinpoint the issue. The GPU temp is going thru the roof. The Celsius temperature starts climbing the moment the computer is booted up and maxes around 128. Thus, why the fan would max out trying to cool it off. Some research tells me that GPU overheating is a common issue due to many things. Since the temperature starts out fairly normal and increases consistently, I feel the temp sensors are doing their job (unless they're somehow incorrectly multiplying their readings). I am going to tear back into it tonight and just make sure there isn't some simple reason why it's not getting enough circulation but my guess is the GPU is just shot. I will report back the findings. [/QUOTE]
