Did ATI Overdrive Auto-Tune (10.11) Screw Up My System?

I recently tried using the ATI Overdrive Auto-Tune (10.11) on my MSI GX740 and in the middle of the test my system shutdown.
I figured it was because it hit the predefined critical temp.
However, now when I try to turn my system on it only stays on for about 20-30 seconds before the system initiates what appears to be a thermal shutdown.
The fan kicks on at its highest speed as soon as my system turns on and it appears to be venting significantly more heat than is usual for the system just starting up.

Is the ATI Overdrive Auto-Tune responsible for this? If so, how? I thought it was just a software mod? If not, what do you think is going on, hardware failure?
