Update. I monitored GPU using Furmark and noted via GPU Z that once my GPU reaches 70-73 degress my pc restarts. I have a 500W PSU. So I am really leaning towards my PSU can't handle it.

I didn't realize how close I had the side fans next to my desk, it was basically pushing the hot air back inside of the case from the GPU. I will continue to monitor and update if I get another crash.

This has been happening for about 2 months now. Whenever I am in a game or watchign a stream the PC completely turns off, not a traditional shut down and immediately restarts. Please let me know if...
