PC fully shuts down, then powers itself back on at exactly 7:11 AM every day. I’m losing my mind.

I’m posting this because I genuinely feel like I’m going insane and I’m hoping someone here has seen this exact thing before.

My PC is fully shut down at night, but it keeps turning itself back on at exactly 7:11 AM. Not sleep, not hibernate, not “maybe I forgot it on.” I mean a real shutdown. Then every morning, like clockwork, it powers itself back on by itself.

What makes this extra weird is that it’s happening at the same exact time every day, which makes me feel like this has to be some firmware / motherboard / BIOS thing, but I still can’t find the cause.

System:

•   AMD Ryzen 9 9950X3D

•   ASUS TUF GAMING X870-PLUS WIFI

•   Windows 11

•   AM5 system

What I’ve already checked / tried:

•   Fast Startup is off / unavailable

•   Hibernation is off

•   Hybrid Sleep is unavailable

•   BIOS APM settings checked:

•   Power On By RTC = Disabled

•   Power On By PCI-E = Disabled

•   Restore AC Power Loss = Power Off

•   Disabled “Allow this device to wake the computer” on the Ethernet adapter

•   Checked Task Scheduler

•   powercfg /waketimers shows nothing

•   Disabled OBS scheduled tasks I originally suspected

•   I just enabled ErP Ready (S4+S5) in BIOS as my latest test, but I haven’t confirmed yet whether that stops the issue

I also checked Event Viewer and the pattern is basically:

•   clean user shutdown at night

•   normal OS shutdown

•   then a clean boot again at 7:11 AM

So it doesn’t look like a crash. It looks like something is actually telling the system to power on.

A few extra details:

•   This only became noticeable once I wasn’t already awake and using the PC in the mornings

•   It has happened multiple times now, including March 26, March 30, and March 31

•   I originally suspected some OBS scheduler tasks, but even after disabling them, it still happened

•   At this point I don’t know if this is a motherboard / BIOS bug, an ASUS software thing, or some hidden firmware alarm stuck somewhere

Has anyone here had an ASUS board do this? Especially on AM5 / X870?

If you’ve seen this before, please tell me:

1.  what caused it

2.  how you found it

3.  how you fixed it

Even if your answer is “it ended up being BIOS / CMOS / Armoury Crate / AI Suite / hidden RTC alarm / board defect,” I want to hear it. I’m honestly just trying to avoid wiping Windows or RMA’ing parts blindly.

Any help would seriously mean a lot because this is one of the weirdest PC issues I’ve ever dealt with.
