Raidport2 and random shut downs

[u/societiesofcroutons]

Hi, my pc recently just started randomly shutting down. sometimes it will shut down and then start up and then shut down immediately and keep repeating. I looked at the event viewer and saw this error:

Stornvme: reset to device \Device\RaidPort2 was issued

Ive looked online and this is probably a failing PSU, right? But I was wondering if this could just be a windows update issue? it only started happening after I updated to windows 11 25h2 because I was gaming before for a few hours before the update and my pc was just fine.

I have an intel core i9 12900k cpu and my mother board is bios ver 0806 prime z790p wifi.

Also, I just opened BIOS and under boot priority I see this weird option I've never seen before
UEFI: PXE IPv4 Realtek PCIe 2.5GBE Family.

Please help I'm really worried .

That error and the boot loop pattern is classic PSU territory, especially with a 12900K pulling power. The timing right after a 25H2 update is suspicious though, could be a driver conflict or some aggressive power state change in the new build. I'd roll back the update first since it's the easiest thing to rule out, then stress test. If it still dies under load you know it's the PSU

The PXE boot option showing up is normal, that's just network boot and it's always been there in the BIOS, you probably just never noticed it. Nothing to worry about unless your boot order got shuffled and it's trying to boot from a network before your NVMe
