If you are not getting a Blue error screen when the computer randomly shuts down, it is more than likely an overheating issue, bad cpu, or motherboard. I also would suspect RAM (memory) but that usually gives an error screen (Blue Screen of Death) before shutting down. Also, when it shuts down, does it reboot on its own or do you need to manually turn the computer back on?
If you noticed, thread starter have been banned, just guessing that his attitude was the cause.
I have suggested him more than once to monitor CPU and GPU temps, as was suspicious about overheating. He stated that CPU temps were in limits. Perhaps I've should been more organized with suggestions, what to do, but it's over now ….
