The front panel header brings bad luck.
The front panel header brings bad luck.
I'm not sure what it could be at all. Why isn't there a short inside the front panel header? That seems unlikely, but it's the only part that makes sense. It's been working well for the last 30 minutes, so maybe it fixed itself or just stopped again. I don't feel confident about it.
Refers to the motherboard rather than the visible front panel. The connector on the front panel. However, this is extremely improbable.
You're referring to the front panel headers on the motherboard. Given that everything seems fine otherwise, you might consider re-soldering the pins just to be safe. There could have been another issue beyond what's visible, but it appears normal. I checked a quick benchmark and the performance was within expectations, and shutdowns aren't linked to any specific tasks. It does seem to occur in the UEFI as well. Could a faulty BIOS chip be responsible for this behavior?
