Constant Re-Boots

[Tetras]

OK I am still holding off replacing any hardware on this PC since I am convinced that the problem is something simple. I am pretty sure that the problem is down to the mobo/CPU and I read that sometimes the CPU might not be getting enough current and is re-booting? The problem does seem to be like something is shorting out. Is this some thing to do with 'AMD Cool n' Quiet' being enabled and 'Global C-states Control' set to Auto? This is slightly beyond my knowledge but is it worth a try? Also setting the voltage to the CPU to 1.35 from the default - defintely don't know what I am doing here…

There have been Ryzen CPUs on the forums that couldn't run stable at idle and disabling C-States or a positive curve fixed it, but ultimately they had to be sent back to AMD and I don't think they developed the fault (i.e. it was like that out of the box).
