Why does Rendering in Premiere Pro CC 2015 crashes whole system?

I don't know if this is hardware or software problem because I've pretty good configuration and the system is crashing due to CPU overheating.

For hardware, I've 16gigs RAM and an AMD FX 8320. That should be enough to do this job.

I'm rendering a 3-4 minutes of video in H.264 in YouTube 1080p quality. The video clips I'm working on are shot in 1080p @ 30fps. The rendering process upto half-way. Somewhere between 50-60% it shuts down the PC abruptly.

What I've already tried doing

• Cleaning media cache database
• Changing the renderer to Software Only from GPU Acceleration (CUDA).

I would like to add that I haven't tried exporting via Adobe Media Encoder because I'm not able to install it at this point.

Can anybody help me resolve my problem?
