Question unexpected system chrashes

[TheRaffster]

Hi,

I built my first pc a while ago and it usually works fine. Every once in a while, however, it freezes up entirely (usually black screen and fast spinning fans) and I have to force a shut down and restart it. Can you help me out? I've tried many things:

1. Uninstalled programms that I thought were the issues but I am now convinced it is random
2. used different software to detect problems (none found)
3. did 2 ram checks (windows and memtest86)
4. updated drivers (manually and with driver booster 7)

My specs are:
Gigabyte X470 Aorus Gaming 5 Wifi
AMD Ryzen 7 2700X (AMD50 Gold Edition)
AMD Radeon RX 5700 from msi
G.Skill Ripjaws V Series 2x 8GB DDR4 3600 (F4)
Intel 660p Series M.2 1TB PCIe NVMe SSD with os
2tb refurbished hdd from WD
psu: CX650M from corsair
NZXT H500i case

I think it only freezes on low loads, I have usually no problems gaming, but it's a real pain while working. On startup, all 4 warning lights on my motherboard turn on.
I initially installed my RAM incorrectly, but it's in the right slots now. The event viewer tells me I have event 41 as critical error (Kernel-power).

Any help is appreciated, thanks

At what speed are you running the RAM?

 

[TheRaffster]

2133 for both I believe

That is not good for a Ryzen 2700X. Start by going in the BIOS and turning on your XMP/DOCP profile and set the speed to 3200MHz. Let's see if it's RAM instability.

What are you temperatures at idle and load on the CPU and GPU?

Did you install the X470 Chipset drivers from AMD's website?

Using latest GPU drivers?

In BIOS I only have two choices for RAM speed profile1 (3600 MHz which the system won't start on and manually sets back after a few restarts) and the 2100MHz that it reset back to now. It also set back to an older bios. I had f50 and it reset to f30. Should i change that again?

I have installed the chipset drivers from AMD's website and I am using the latest GPU driver.

Idle CPU and GPU temperatures are between 40 and 50°C. Do you have a suggestion for benchmark programms?

update: I managed to change the memory speed to 3200MHz. Will updating the bios mess with that setting?

give full name and model of ram also unplug the hdd from system and see if it report kernel power .

This is how it was sold:
G.SKILL Ripjaws V Series 16GB (2 x 8GB) 288-Pin DDR4 SDRAM DDR4 3600 (PC4 28800) Desktop Memory Model F4-3600C19D-16GVRB

Okay I'll try to go without hdd for a while
