Hello everyone, haven’t posted on the forums much lately since what little free time I have had I spend playing games with the wife. At least until a few days ago.
I have a Ryzen 3900x system that is randomly shutting off with no error code in windows reliability monitor. It does it while gaming, rendering and even idle on the desktop. It has even shut off in the BIOS.
Nothing is overclocked other than my Memory because I want stability with this system.
My current config.
AMD R9 3900x with Noctua NH-U14s
G.Skill 2x16gb 3600mhz CL16
Asrock B550 PG Velocita
2x Samsung 970 EVO Plus 1tb
Titan Xp with EVGA CLC cooler
Fractal Define R5 case with 3 Noctua A12 fans.
EVGA G3 1000w PSU
I have also tried the following and used the following parts to try and diagnose the issue.
Disabling XMP and running at 2133mhz
Manually setting ram speed and timings
Used a set of Crucial 2x16gb 3200mhz Ballistix AT
Tried using my wife’s MSI Ventus GTX 1660
Disabled ECO and enabled eco mode on my power supply
Directly plugged PSU into wall outlet instead of my surge protector
Changed the power cable on the PSU
PBO was enabled for the first day I had the system and it has been disabled since. My single core clocks suffered and it got a little hot for my taste.
I have stress tested the system using several methods. Memory tests can run for hours with no errors.
This has started in the past 3 days. I have had the Asrock Motherboard since June 19th and previously had an Asus X570 Tuf Plus motherboard that I got an RMA refund after it started having trouble posting. The asus motherboard was 100% stable when it finally posted but took 4-6 attempts every time I used my PC. With the Asrock board it was stable for the past month until Monday.
Bios has been the same since I updated it on day one. No new bios revisions are available except for a beta bios.
I have not had a thunderstorm in the area recently and no power issues. I usually unplug my PC when there is one.
What else can I do to determine if the CPU, Motherboard or PSU is at fault? I have run out of ideas at the moment.
