Hello, a brief introduction is necessary here. I'm a system/server engineer, web designer, tech admin and several other things. I built my own pc, wired my network and so on, I dare to say I'm not exactly the average user, so I beg you not to give me "restart everything" "you messed up" "unplug" "remove customization" "reinstall" kind of answers :) Posting here is already outrageous for me, as I never ever needed help with any of this in like 20 years. Now that being said, I have a fully functional freshly built custom pc. I don't like to talk about parts often but the relevant bits are 1200w platinum psu (way more than enough, with no stability issues whatsoever) and Gigabyte Z690 UD AX DDR5 motherboard.Issue at hand - pc restarts after being instructed to shut down, with the following conditions:
- Click shutdown in Windows, let it do the procedure, pc shuts completely down and restarts roughly 1 second later.
- Click the power button once, let it do the procedure, pc shuts completely down and restarts roughly 1 second later.
- Within Windows, hold power button for 5 seconds, pc shuts completely down and does not restart.
- Before Windows boot, hold or press power button, pc shuts completely down and does not restart.
- Within Linux booted from USB key, if I click on shutdown, pc shuts completely down and does not restart (which is the relevant bit that makes me say this is not a BIOS issue or hardware).
What I already tried to fiddle with, as per many other topics about this:
- Enable/Disable Fast Boot
- Enable/Disable Secure Boot
- Pc does not crash in any way (so no crash events) but power on after crash and power on after ac loss are both disabled from the bios
- Dummy load setting in bios on auto or disabled makes no difference
- Unplugging my network cable makes no difference
- Unplugging my devices (albeit not all of them at once) made no difference either, but wouldn't make sense given it does shut down with everything plugged in from Linux
- S3 state is disabled from BIOS, so it's not that either
- None of my devices are set to turn the pc on currently, and again given it doesn't happen when I turn it off from Linux it's not a factor
- I don't have any remote control or anything weird going on
- EDIT, ADD: Checked the registry, no pending reboots for anything, and even then surely not so many times
- No viruses
- Last but not least - the OS is not funky/broken either, I cloned it yesterday on the NVMe drive that I'm using now, but previously I was on an SSD drive that used to be in my previous computer and I had simply transfered it over to the new pc. My old pc did not have this restarting issue so it is NOT a custom program or something that I configured to turn the pc on.
Please do not tell me to update my drivers, been there done that, everything is fully up to date given it's been installed for a week.
Please do not tell me to update my BIOS, been there done that, or it wouldn't have started in the first place as the cpu wasn't supported with the older BIOS version :)
Now, before I lose what's left of my sanity, does anyone have a clue about what I might have forgotten about? I'd appreciate it immensely. Thanks.
P.S.: no overclock, ever, anywhere. Just in case you thought I pushed something too much that made it to restart. Nope :)
P.P.S.: I've been told to ask here by a moderator on the official forum, here: 99aa2fa7-9f8a-4058-8d18-c152992d0d41
