Hi, my PC started to shutdown randomly, regardless if there is heavy load or no. Event log doesn't show anything except unexpected shutdown, I tried stress tests also haven't resulted in shutdown.... I've noticed that extension cord fuse was down so I replaced it with cord that has no fuse.... It was ok for about 6-8 hours.... Now it started again.... I suspect PSU, however under heavy load it should crush instantly... Any ideas?

whats the psu watt rating? check .dmp file after crash, google dump file analyzer

Tech A 2024-08-05 18:01

i got corsair rm850 gold (850w) 12900k and rtx 3080, so more power than needed I suppose ( no Christmas's tree inside ) no minidump after crash 🫠

Tech C 2024-08-05 18:02

reseat all the components

Tech A 2024-08-05 18:03

it crashed like that in bios as well, so shouldn't be OS related...

Tech B 2024-08-05 18:04

sporadic crashes could also be attributed to overheating CPU reapplying thermal paste have solved similar issues for me

Tech C 2024-08-05 18:05

thats why I said to reseat all the components. Also it could be not only CPU overheating but also the GPU.

Tech A 2024-08-05 18:11

I did a stress test and monitored the temperatures, nothing crashed and everything was in acceptable values... the pc crashes even in idle...

Tech A 2024-08-05 18:12

if I had intel 13'th or 14'th gen I would know who to blame first 😏

Tech B 2024-08-05 18:14

what if 12 gen wanted some attention and decided to join the rest

Tech A 2024-08-05 18:25

Then it's time to go back to AMD

I used amd for 15+ yrs never had an issue 😏

same CPU ?:)

Tech B 2024-08-05 18:37

☝️ this one i installed this year previous i had ryzen 7 2700x for 10 years at least and its still running my plex server

ok, restarted all components. Poured some thermal paste, let's see what happens...

Tech A 2024-08-05 19:01

PS: had fx8350, now my father is using it as his office pc. I was exploating it since 2013 till 2023

Tech D 2024-08-05 19:03

I had that cpu before, it was great since you could use your pc to play something while you fry some eggs on top of it 🍳��

Tech C 2024-08-05 19:05

ok, restarted all components. - I said "reseat", not restart.

Tech A 2024-08-05 19:24

That's what I did... Also restarted cmos ( it's 11:24 hard to read on the phone 🫠)

Tech C 2024-08-05 19:28

then the last resort is VooDoo

Tech A 2024-08-05 19:35

That was like 20+ years ago...

# Fix Random PC Shutdowns with No Event Log Errors

## Problem
A workstation with Intel 12900K CPU and RTX 3080 GPU powered by Corsair RM850 Gold PSU experienced random shutdowns during both idle and load conditions. Event logs only showed unexpected shutdown entries with no specific error codes. The system crashed even in BIOS, ruling out OS-related causes. Stress testing with temperature monitoring showed acceptable thermal values and did not trigger shutdowns. No minidump files were generated after crashes. The issue persisted after replacing a blown extension cord fuse.

## Resolution
1. **Reseat all components** - Remove and reinstall RAM, GPU, CPU, and all power connectors to ensure proper connections
2. **Reapply thermal paste** - Remove CPU cooler, clean old thermal paste, and apply fresh thermal paste to eliminate potential overheating issues
3. **Clear CMOS** - Reset BIOS settings to defaults to rule out configuration issues
4. **Check power delivery** - Verify PSU connections and consider testing with a different power supply if shutdowns continue
5. **Monitor temperatures** during normal use, not just stress tests, as sporadic overheating can occur outside of synthetic loads

Note: If the issue persists after these steps, the PSU may need replacement despite adequate wattage rating.
