New Ryzen Build Issues, Please Help!!!

[Brock Walker]

My pc shuts down randomly while playing games. first freezing, then the game will come back for a few minutes, then the computer will shut down. None of the parts I’ve RMA’d have helped the issue, i recently put the power setting to high performance, and i can get a few hours of gameplay now, but the same issue still occurs, also when it shuts down the lights on the motherboard are still on and the cpu error light is illuminated. Should I RMA the cpu next or could it be something else? And no there are no overheating issues, nothing is overclocked (besides the GPU, it has a slight OC from factory). Ive been at this for 5 months, I purchased everything new, and I just want it working properly

Here is what I've tried so far:
-ran with a single stick of ram -tried either 8gb stick
-checked drivers, all were updated
-CHKDSK -no issues found
-sfc /scannow -found corrupt files -DISM- the restore operation was completed successfully
-checked all connections to the psu and motherboard
-cleaned off original thermal paste, and applied a silver based paste
BIOS has been Updated
-voltages all seem good
-temperatures aren't reaching high enough levels to shut the pc down
-changed power settings and fan curve on
Gpu
-upped the fan curve for my case fans, CPU cooler and my gpu fans
-had my GPU RMA’d
-had my motherboard RMD’d
-adjusted the power settings to high performance mode.

Errors in Event Viewer
-Certificate for local system with Thumbprint is about to expire
-Error ID 3 genericroaming error
-Windows Kernel event ID 41 error "The system has rebooted without cleanly shutting down first"

Here is my build: - AMD Ryzen 5 1600 - Gigabyte GA-AB350-Gaming 3 - Corsair Vengeance LPX (2 x 8gb) - Zotac GeForce GTX 1060 AMP - EVGA Supernova G3 650w 80+ gold - Samsung 850 EVO-series 250gb SSD - Western Digital Caviar Blue 1tb

So the computer completely shuts off, fans and everything? Sounds like a weird hardware issue. I'd be very surprised if it wasn't either the cpu or the motherboard that's at fault. I'm not familiar with any cpus that work for a few hours then suddenly shut the computer off, so more than likely it's the motherboard i'd say.

When you RMA'd the motherboard, are you sure they didn't send you back the same board claiming it was fine?

Get a different motherboard, preferably one that's known to be working but honestly any new motherboard should suffice. It's incredibly unlikely that two motherboards would give you this same problem. If the problem persists on a new motherboard, it's probably the cpu.

I checked the serial number and it was the same board that was sent back, so I decided to buy an asrock killer sli, my pc is working great now. Thank you
