Random restarts (but maybe not on other OS?)

Update.

With the GPU removed, it ran 24/7 for about a week without restarting.

Two days ago, I put the GPU back, with these changes:

  • Disconnected/reseated GPU power cables at PSU end, and of course paid much attention when seating all other GPU connections
  • Flipped PSU switch from ECO to AUTO

The first (reseating) isn’t a “change” per se, but of course may be important if I’d missed something loose before.

The second, changing the PSU mode…

I have found search results where people have said taking their PSU out of ECO mode solved a rebooting problem, but in the same posts other people saying it shouldn’t matter.

Supposedly ECO only affects fan but not power delivery. But it is an easy thing to test, so I flipped it and will let it run in AUTO for a while.

I have never heard the PSU fan kick in while in ECO mode. In AUTO, it seems to run all the time. (The fan is louder than all my other case fans, despite being marketed as “quiet.” But it’s not terrible.)

If it runs a week like this, I may try flipping back to ECO and see if the restarts resume.

Two days without restarting so far. I’ll be back.

Well, I didn’t wait a week to flip it back to ECO, as it was too noisy for me and had been running fine. It’s not rebooted since I flipped it back (and not since I had removed and then reinstalled the GPU.)

So it seems the moral of the story is “Always check/reseat connections even if you are ‘sure’ they are OK.”

In my case, the cables between the PSU and GPU, and GPU riser cable. ricklinux had mentioned reseating RAM but I didn’t do that. (But I did run memtest86+ for over 9 hours with no errors.)

I’m calling it done. I appreciate all the replies, but I’m not sure if any individual one is exactly “the solution.”

Personally, I think @z580c’s suggestion came closest to helping isolate where the issue existed. Glad to hear you’ve had success though! :sunglasses: :+1:

FYI this isn’t over, still restarting, not sure what to try next, maybe see if I can get all new PSU/GPU cables, maybe I bent some a bent some a bit much in my zeal for “cable management” (i.e. “making it pretty” lol.) Other than that, no idea, already on the latest BIOS with Intel’s “fix” so it’s either not that, or already damaged. But, I’ve never read of spontaneous reboots being a symptom of that problem.
