Temperamental system instability messageon the post screen

On start up your BIOS didnt like some setting or response from other hardware in your pc, as such it then rebooted again and displayed this message so your aware that it wasnt stable last start up.

Nothing to do with windows.
 
any tips on how to troubleshoot this though/ ideas what it might be
It usually means its borderline on something, Ie it didn't like start up voltage for cpu etc

I presume your system is overclocked?

Not a massive area of my expertise im afraid.

try running the system for a few days stock and see if the message goes away?

I have found on some older over clocked system this message once ina blue moon appears but then can usually just be ignored, but yours sounds quite regular.
 
Yeah it's a overclocked ryzen 1500 chip

I could take it back to scan but it's fairly far away so it's a pain in the ass. The built system isn't exactly light either so I don't really want to carry it back. They'll probably blame the other components I didn't buy from them anyway.

I did notice the cpu core voltage was fluctuating by 10mv constantly. Is this normal?

I'm suspecting an over optimisticly rated psu.

Occassionally I would have it randomly shutdown itself cleanly( i.e. the screen shows windows is shutdown) . IT's not windows update thats doing it since it says am up to date.

It's not over heating because everytime it does that, when I turn it back on immediately after the cpu die temp is only 40 degrees c. I have been monitoring it, never seen it go alarmingly high.

Also more often then not when it does randomly shtudown, it struggles to tun back on i.e. it switches on then switch off immediately but it evetually does power on.

I have a cosair 580w psu connected to the following

1 ssd
1 500 gb hdd
3 fans inc the cpu fan
an asus GTX1050 gfx card

Is the psu big enough/ what do oc'ers generally use for a psu?
Which rail does the cpu core voltage come from? i.e. 3.3v or 5v?
