New SER8, no BIOS after first Windows update

Got a new SER8, initially BSOD repeatedly on initial Win11 install (scanned the included USB and it found Repavll trojan or something on winpe.exe)

Got it to install via official Windows install media

Installed AMD drivers, then windows update had a billion things, then reboot…

And now no BIOS at all, black screen. Tried turning it off and on a few times. Just gets really hot

Any idea what’s wrong?

Could it be that windows update downloaded a BIOS update and it’s now bricked?

It won’t even POST, there is no fan activity, it just gets really hot.

I can’t reinstall Windows as a result…
