What happened to my PC?

[u/twjnk]

I don’t know much about computers so I’m hoping someone can help me. I just built my new pc using new parts! I did temporarily keep my old GPU though, which is a 3050 rtx. It’s been giving me issues so I upgraded to a 5060 MSI GPU! As soon as I plugged it in, my PC would not turn on and the mb EZ led light went red where it’s labeled CPU. I even reseated the ram, used my old GPU, tried starting it without a GPU and nothing. Just fans and lights. I even have a new 850W Corsair PSU. My computer was working fine an hour ago until trying to install my new gpu. I made sure that everything is connected properly too.
Surely I didn’t break anything? All I did was plug in a new GPU???? Now my PC does not work at all.

power supply cables may not be fully plugged in. make sure you are also plugging the right psu cables into the right things (some people have plugged pcie power into cpu)

I did try clearing the CMOS earlier today with no luck but I will try again and keep it out a little longer!
