I'm running into a strange problem with my PC where it refuses to shutdown properly. I recently reinstalled my motherboard—I've switched between a B650 Tomahawk and an X870E Aorus Elite X3D several times. After swapping back to the X3D, the PC shut down cleanly once but started rebooting right after that. I tried pulling USB devices and messing with the power button, but nothing worked until I reseated the 24-pin and 8-pin CPU cables, which somehow fixed the issue. I've never seen anything like this before and I'm trying to understand what might have caused it. Has anyone else experienced similar issues?

Why are you switching motherboards so frequently? Also, do you reinstall Windows with each switch? Is the B650 still working okay?
I build a lot of PCs for friends and family, so I pass on motherboards at a cheaper price. I initially planned to stick with the X870E Aorus Pro, but it had some noticeable coil whine. The Aorus X3D lineup seemed better priced with more features, like no GPU lane sharing when using two NVMe drives. The B650 seems fine now, but I still can't figure out why reseating those cables fixed the shutdown issue.
