Good morning everyone. Yesterday I built a new PC, connected it to my monitor and the monitor shows "no signal detected". When I plug the monitor to my old laptop, it works perfectly fine. The new PC has still no OS installed as I was planning to install PopOS. I connected it using HDMI-HDMI cable. I even tried to connect the new PC to a tv, still without success. There's no dedicated graphic card, so there's no vga slot. Everything seems to be connected fine. The fans start spinning, lights go on. What could be the issue here?
 
Guys, when you look at debug LEDs on a motherboard, should they be on or off? I.e. when they are on it means there's a problem or when they are off?
Debug LEDs just run threw the boot process and then go off if there stuck on a light it indicates a problem.

Then I messed up the build. The CPU and DRAM are on. I hope I didn't bend the CPU pins...
 
The pins seem fine. I took the cooler off, get rid of one RAM stick. Still the same issue. I think the CPU is getting the power since it's getting hot after turning the pc on.
Try a stick of memory in each slot but wait 5 minutes to boot each time as the motherboard will be trying to train the memory.

This is common on Ryzen.

IT'S ALIVE!!! Thank you soooooo much, folks! I need to run some errands, but when I'm back in the afternoon, I'll attempt to install the system.

Once, again, huge THANK YOU to all of you!
mickyflinn, you were right, I guess at first the RAMs weren't pinned properly and later I just wasn't patient enough.
