New PC builder boot issues

[IKright]

I just built my computer and the light is on, CPU fan is spinning, but there is no video signal.

I am using an integrated graphics card

My components:

Ryzen 5 5600 G  cpu

Asus prime B550M-A csm mobo

G.Skill Ripjaws V 16gb (2x8gb) ram

Western Digital Black SN750 SSD

Seagate BarraCuda 1tb harddrive

EVGA Supernova 650W 80Gold PSU

I am aware that the 650 watts is probably overkill, I got it to be efficent and modular. I have installed everything and have turned the computer on using the screwdriver method, which prompts the fan to spin, light to come on, and hard disk to spin. Any idea what is going wrong? I think it might be about bios issues but I do not know how to do that..? I can add pictures if anyone is willing to try to help me troubleshoot. Thank you

Reseat CPU/RAM, ensure enough mounting pressure for CPU fans, reset CMOS. Try only using SSD and 1 stick of RAM first. Ensure RAM is in correct slot configuration too

Done; no signal still. I might be resetting the CMOS wrong though because the instructions are a bit strange. What is "enough" mounting pressure? I am usng the stock cooler that comes with the 5600G

Update, seems to be a bios issue, where the mobo and cpu are unable to talk to each other. Looks like I need to get an older cpu to update the bios, then put the 5600 back in and it will work. would use BIOS flashing but I do not think my mobo has that sadly
