Question Strange system crashes - - - I've never experienced anything like this ?

[L2Frame]

Hello !

I am experiencing random, strange system crashes like following:

System suddendly crashes, screen goes off and the most signficant part is, the fan of the GPU (Powercolor Radeon RX 580 Red Devil) starts spinning up and down quickly. System load doesn't really matter when it happens. Can play games for hours and nothing happens, but then, if i'm doing lazy tasks like browsing, writing etc., it crashes like described before, but as mentioned, sometimes, but rarely, happens also while gaming. Always the same symptoms like i described before - - screen goes black and GPU fan spins up/down quickly.

Now comes the strange part:

If i put a secondary, old GPU (which is not in use), into a free PCIE-Slot, the system runs and runs for weeks without a single crash ! As it can be seen in GPU-Z, PCIE-Speed goes from x16 to x8 for both cards. I could live with this "solution" but to be honest, i don't need 2 GPUs in my system and don't want to waste performance and power usage. I assume it has something to do with powermanagment and fancontrol of my GPU, but i maybe wrong.

System-Information:

MAINBOARD: Asus Prime X370-PRO (Bios v 6203 (latest))
CPU: Ryzen 2600x
GPU: Radeon RX 580 Powercolor Red Devil
RAM: 2x8GB Patreon 3200 C16 Series
PSU: Arctic Cooling 550R (very old, but rarely used)
OS: Windows 11 & openSUSE Tumbleweed (both affected by crashes)


Right now, i turned off C-States in BIOS and see if it helps....

Any suggestions on this ? Maybe someone experienced something else ? Help is very appreciated !

PSU a likely suspect.

How old is "very old"? History of heavy gaming use - correct?

Look in Reliability History/Monitor and Event Viewer for error codes, warnings, or even informational events just before or at the time of the crashes.

Increasing numbers of errors and varying errors are a sign of a faltering / failing PSU.

PSU may be nearing or at its designed in EOL (End of LIfe).

Assuming the PSU is the Arctic Cooling Fusion 550R, it was released in 2008 with a 3 year warranty. It came with 2x12V rails of 17A each. Combined 408W. It appears to have been replaced in 2012 by the very similar Arctic Cooling Fusion 550RF.
