My PC won't turn on. Any advice on what I should do.

Level 7

I tried turning on my pc and it won't boot, I'm using a Asus Rog Strix B550-f Mobo the light on the logo is on, but when I press the power button the light flickers and won't turn on. I tried renoving the battery, tried the pressing the bios fblk and the CLR_CMOS fix and it still didn't turn on. I do not have any way to test if its other components but all I can say is that everything was working fine untill today. Heres an example of my situation

Hello, @UnreqlDecision 

Thank you for providing the video. 
May I inquire about your motherboard model, whether it is the ROG STRIX B550-F GAMING (WI-FI), ROG STRIX B550-F GAMING, or ROG STRIX B550-F GAMING WIFI II?
Could you please specify the circumstances under which the boot failure occurred? For instance, was it after a BIOS update?
When facing the issue of being unable to boot, did any Q-LED indicator light up?
If so, kindly refer to the corresponding indicators in [Motherboard] ASUS motherboard troubleshooting via Q-LED indicators for troubleshooting steps.
If needed, we suggest you refer to [Motherboard] Troubleshooting - No Power/No Boot/No Display and test with minimal components to isolate the possible cause.

Thank you.
