Freeze on boot / startup

[diggi5]

Hello!

 

Specs:

Gigabyte Z690 UD DDR4

i9 13900K

BIOS Version F22

 

Problem:

CPU Upgrade - Motherboard (BIOS), I switched to the "Gaming" mode which disables all E-Cores and only leaves on the P-Cores, currently i'm trying to switch back to the "Default" mode which is 8 P-Cores and 16 E-Cores but everytime I try to save and exit the bios it freezes at this point (reference image). https://imgur.com/a/vU2IXqs

 

I tried turning on/off XMP, turning on/off Secure boot and turning on/off Fast boot.

I also reinstalled Windows off of a USB Stick but to no avail.

 

If any of you need more information please ask, i'm absolutely out of ideas on what to do.

Start with removing the CMOS chip to completely reset BIOS, try again. If no workey, I'm to start MemTesting.
