Question GPU blinks when pressing power button but computer doesn’t start at all ?

Apr 30, 2022
Yesterday I reset my pc like 7 times trying to turn on secure boot in bios to play valorant. After playing for a few hours in secure boot, I shut it down and went to bed. Now when I try pressing the power button the gpu blinks and then nothing happens at all. I’m so lost and what I should do bc I tried some things online and nothing worked. I put a screwdriver to the cmos pins and waited 5 min, still nothing. I also put a new cmos battery in.
I have:

b450 Tomahawk Max MOBO
EVGA 500 BQ,
Radeon 5600 XT
