Question Weird System shutdowns

[pamdu]

Hello,

My System shuts down from time to time unexpectedly and I hope you guys could give ma an advice.

I suspect the PSU, but don't know how to verify without buying a new one first.

Specs:
OS: Debian Trixie / KDE Plasma
Processor: 24 × AMD Ryzen 9 7900X 12-Core Processor
Memory: 64GB Corsair Vengeance DDR5-5200
GPU: AMD Radeon RX 6750 XT 12GB
MainBoard: ASUS TUF Gaming X670E-Plus WIFI | AMD X670E
PSU: 1000W - Corsair RMe Series


The thing is, my System shuts down only while playing certain Video games. I never encountered the shutdowns in any other circumstances. Also, there are games like Red Dead Redemption 2 which never made my System to shut down - even tho this game uses way more GPU that any other games that I played. It does not seem to be effected by the raw voltage usage. (GPU useage was like 75% for RDR2, but shuts down occurred on Indie games)

That fact makes me question if it is in fact the PSU, but I don't have any other guess.

Things I tried:

• Checked the logs journalctl -b -> without any error entries (In case of Cooling issues)
• Made some Memorytest (I forgot which ones, guess it was memtest)
• Did run some Benchmarks -> Did no notice any suspicious things.

Not to forget, after a shutdown, the GPU LED's are still on. I cannot turn the Computer on before I manually turn off the PSU until the GPU LED's are off.

I suspect that anything in my System has Issues regarding Voltage Spikes and turns off (And RDR2 seems just to be Optimized enough because of PS3 Import?)

Do you have any Idea how I could verify that this is an PSU, or Identify if it's related to any other Device. Are there other Logs somewhere that might give me some hints?

Thanks in advance,

Pascal

Look in Reliability History/Monitor and Event Viewer.

Either one or both tools may be capturing some error codes, warnings, or informational events just before or a the time of the system shutdowns.

Start with Reliabiity History/Monitor. Much more end user friendly and the time may reveal a pattern.

Event Viewer requires more time and effort to navigate and understand.

Power down, unplug, open the case.

Clean out dust and debris.

Verify by sight and feel that all connectors, cards, RAM, jumpers, and case connections are fully and firmly in place.

Use a bright flashligh to inspect for signs of damage: bare conductor showing, melting, corrosion, browned or blackened areas, swollen components, loose or missing screws. kinked or pinched wires.

Hopefully something may just have wiggled a bit loose and some connectivity is lost causing the shutdowns.

Thanks a lot for the quick answer,

I use a Linux OS and cannot check Event Viewer or Reliability History.

I checked the Cables and could not find any that where loose, but will double check again later.
No damage to the electronics were visible.
PC is Cleaned.

As the shutdowns are not reliably reproducible, it's not possible ATM to say if that's already helped.
