Question No signal after upgrading CPU from Ryzen 3 2300x to Ryzen 5 3600, new motherbroad Asus prime B450-plus, with ready for ryzen 3000 on the box.

Hey, first time writing here.
I have a problem, hopefully you guys can help
I wanted to change a old CPU to a new Ryzen 5 3600. After I changed it, i turn on the pc, everthing turns on, fans and lights, but the monitor says no signal.
I tried going back to the old CPU, Ryzen 3 2300x, the same thing happened no signal on monitor.
Okay, I removed the RAM, and changed it, to some RAM from another PC I have (That works) still nothing. I tried moving the RAM around, nothing.
So I took out the battery on the motherboard, and left it out over night, just to be sure. Also no power cable was connected.
Working on it this morning, still nothing. So I went out and got a new motherboard, the Asus, prime B450-plus, hoping that was the problem.
Still no signal, with the GPU in, HDMI in the GPU, the working RAM, the new and old CPU, (both does nothing) and tried taking out the battery of the new Motherboard again and leaving out for 10 mins. PSU has also been changed to the working PC's still no signal.
I also tried two different monitors, no signal on both, but when I try the computer that are working both monitors work.
I can't even get to the bios, as the monitor shows nothing.
I am so lost, any good ideas?

Welcome to the forums, newcomer!

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model.

Which slots are the sticks of ram populating on the motherboard? As for your motherboard, what was your older board?

Thank you so much for taking the time out of your day, to explain this to me. I will add it in the main question right away.

I assume you had a monitor connected to the 1080 card for all tests, and not the graphics outputs on the motherboard rear panel?

Yes only to the 1080
