Happening during cold boots and games leads me to believe it could be a power supply issue. It's common for lower quality ones to go out after a few years. If you are over clocking anything (Ram, cpu, gpu) you could try resetting those to the default values and see if you can replicate the issue.

Nothing is being overclocked ( I think ).

Also after a restart, it works fine for the rest of the day.
