Pc not turning on and no sign of power through motherboard

[Jeffvey]

Hi, I have had an aorus b450 pro wifi mobo for about 6 months with a ryzen 3 2200g, and have just went out to buy a 3600x and some g skill trident z memory. I knew that I needed to do a bios update but when I first got it I just put it in hoping it would work but it didn’t. After switching it with the ryzen 3 again, I downloaded the f32 bios update along with the EC FW update thing so that I wouldn’t have memory issues later on. After downloading the update, I downloaded the f40 update which is supposed to allow third generation ryzen chips to be compatible. After switching back to the the 3600x again, it first brought up a black screen with the text saying to insert boot media and restart or whatever so I tried restarting the pc, hoping it would work, and the most I got was the screen flickering to the aorus loading screen (shows bios, q-flash, etc), before flickering off. I thought there was still something messed up with the ram, so I tried reinstalling my old ram to see if it would work, but it still ended up doing the same thing. I eventually concluded that I was still missing some sort of update so I reinstalled the ryzen 3, and when I connected the power supply and flipped it on, the usual aorus falcon lit on for a moment, and off (normally happens) but when I powered on, nothing happened at all. Which leads me to this moment.

sorry if this is littered with grammar errors or stupid things as I am not an avid pc enthusiast.

thanks,
