Random, complete shutdowns.

[Jihakuz]

Hi,

This has started to drive me crazy. My computer will completely shutdown (no BSOD just power off) and will not turn back on until it's been power cycled.

I don't have any overclocks, and it's not to do with the load on the PC. I can run Cinebench over and over with no issues, I've even had it before that it shuts down when left idling.

I have a feeling that it's my motherboard as I've heard that early Ryzen boards were always a bit jank. My specs:

Ryzen 1800X

MSI X370 SLI Plus

1x16GB Corsair Vengence LPX

MSI Armor 1070

Some silverstone modular power supply.

 

Any help in even identifying what the problem could be would be greatly appreciated!

I would first take a look at your PSU, shutdown problems can be MB but biggest culprit is a PSU bought as an afterthought or not researched properly, when really it is the heart of your whole machine.

I'm pretty sure it's not my PSU, I've swapped it out before and had the same issues. Both the one I regularly use and the one I swapped in were nice ones, not some ones I picked up on ebay for nothing lmao. Just can't remember the name of the one I have atm

What about your boot drive? Could be faulty sectors

PSU would be my go to answer but as you said tried 2 psu's, it could be a hard drive crash, or sata port died, try the drive in another port, are you on a UPS or direct to wall any issues with power to the property, brown outs and such like, the other direction to go even though it is happening when not under load is temperature, or like you said MB, have you tried factory defaults, oh and silly as it sounds see if the latest frikken windows update (if it enabled idle shutdown or some other junk).
