Welcome to ask.:fedora:edora @snapak

Could you please give us more info’s as :

inxi -Fzx in terminal and post the output as </> Preformatted text here.

It is also a good idea when you start reading here > #start-here

I have to guess, because of missing info,s.
You might have a monitor who is not supporting 144hz.
Try while booting to press Esc or Shift and select the rescue/low resolution mode to boot and then change the refresh rate back to the lower value.
