PC stuck in a boot loop – stable on BIOs screen

So, here are some things I’ve tried:

Reseated CPU, RAM, PSU cables, CPU fan cable

Moved RAM to different slots, tried it with 1 ram stick and switched them

Reset CMOS

Removed SSD

Removed GPU

With or without the SSD it will constantly reboot, and when I tried to access the Windows setup on a USB it will show the windows logo for a few seconds and continue looping.

Mobo has no error lights or codes

I can sit in the BIOs screen without any shutdowns

Any advice is appreciated 👍
