Cant boot (black screen) after changing Infinity fabric frequency to "Auto"

[Slide]

Just finished building my PC, press the power button and, finally ! I just create life ! I went in the BIOS, activated EXPO profile clicked "save and exit", everything worked perfectly. Then I went in the BIOS again set the infinity fabric frequency to "auto" and everything is broken now (only thing working is fans but a little faster than before, temps were fine tho). I'm not really sure its related but everything was fine before. Hope you guys will be able to help me and I thank everyone in advance (+ sorry for bad english).

My system :

CPU : AMD Ryzen 7600x

RAM : Corsair 32gb 6000mhz 36-36-36-76

GC : Sapphire Pulse Radeon RX 6700

MB : Gigabyte B650M Gaming X

PSU : EVGA 750W 80+ Gold

if your pc doesnt boot then try reset cmos so bios settings will be reverted and you can boot
