New Build Randomly Restarting Without Any Blue Screen

Recommended Posts

Posted · Original PosterOP

Hi and thanks in advance for any help. I just built my first system using a mix of new parts and some that I had already. The system is occasionally restarting without any blue screen. Event viewer just shows the critical power event without any bug check codes or sleep in progress timestamps. The screen just goes black and then it reboots. This can occur when nothing is happening (idle) and under load. CPU temperatures during each of the three reboots that have happened thus far have been 65, 71, and  48. I've also ensured that the CPU cooler is mounted tightly and securely and I believe it's good because Prime95 temperatures don't exceed 88 C. Regular loads don't exceed 78 C. The Windows installation is fresh as well and I've installed all chipset drivers and updated the BIOS to the latest revision. As a starting point I'm running Memtest 86 but so far no problems have been found and I'm on the 4th pass. My gut says it's the power supply, but I really don't know. Here's my system specs:

 

Old parts:

 

- EVGA GTX 1060 3GB

- Western Digital Blue 1TB SSD (non-M.2. Data drive)

- PNY 250 GB SSD (non-M.2. This is the boot drive. Windows freshly installed from scratch)

 

New Parts:

 

- Ryzen 5 3600 @ stock with stock cooler

- 32 GB G. Skill Ripjaws 3600MHz C16 (2 DIMMS populated in slots 2 and 4 per the motherboard instructions. Profile enabled in BIOS)

- ASRock B550M Pro4

- NZXT C750 80+ Gold PSU

- Cooler Master Masterbox Q300L

 

OS:

 

- Windows 10 Pro 1909

Run a memory diagnostic to check for memory errors. You can do this by searching Windows Memory Diagnostic in the Start Menu and running that utility. It'll restart the computer and run a memory test.

As I stated above I am already running Memtest 86 and I'm on pass 4 currently with no errors. Should I also run the Windows Memory Diagnostic once that's done? I have Memtest 86 set to run 5 passes.

I'm still struggling with this and banging my head against a wall. Does anyone have any idea which component might cause this? Should I just return and replace all of the new parts? I understand it's rare to be the CPU, so maybe just the motherboard, PSU, and RAM?
