Constant Re-Boots

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).
 
OK I know I might be flogging a dead horse here but I have found that when I am running AIDA64 Extreme on my PC it never re-boots… So I thought I would play Skyrim on the sneaking suspicion that when my PC is under a certain load it will behave. Well I played the game for a solid hour and it never re-booted. Could this be to do with voltages? I have noticed that when my system does re-boot sometimes the onboard EZ Debug LED CPU light stays on indicating a fail - dodgy or knackered Threadripper 1920x CPU perhaps? AIDA gives the CPU Core as 1.440V and the CPU VID as 1.225V. I haven't got a clue what these should be???

What is your core voltage at idle?

Mine sometimes goes very low but averages around 0.800v. Maybe yours does the same and reboots because it is to low.

 
@Tetras Sorry didn't check back on this thread I will give your suggestion a go but at the moment the PC takes like half an hour to boot up sometimes - deffo something wrong with either CPU or mobo. The Onboard LED CPU light stays on until the machine boots, the manual suggests that this means 'CPU is not detected or fail'. So I am not sure even voltages would do anything since this before it reached the BIOS?
