Question "no Input Signal" When Turning On The Pc (on Monitor)

Hello.

I am fairly new to building PC's.
I got the ASRock B450M Steel Legend MOBO and wanted to now:
BIOS version P2.90 supports the AMD Ryzen 5 3600.

If I turn on my (newly) built PC, fans are spinning, LED seems to be working and you can hear it turning on, I get a blackscreen and can't get into the BIOS, "No Signal Input" it says on the monitor.

- I know that the monitor works 100% because I checked it with my other PC
- I checked the HDMI connector
- I checked the PCIE connector that connects the PSU to the GPU (Nvidia GeForce RTX 2060)
- I checked the DIMM slots if the RAM is correctly placed into the MOBO
- I checked if the GPU is correctly placed into the PCIE x16 slo

- HDMI is plugged into the GPU port

I am wondering what's causing the issue then. Someone someone suggested that I try to connect the GPU to the monitor via a DVI cabel because of "secure boot".

If somebody has got any suggestions on what to do to get into the BIOS, I would gladly appreciate it.

Thanks.

It may not have bios 2.9 loaded on the motherboard. Take it back to the dealer you bought it from and ask them to flash it for you. Or is there a sticker on the bios chip that says what version it is ?

Okay so I may have found the problem.

I literally tested everything, every cable, the GPU, the MoBo HDMI port, BIOS reset 2x, switched RAM slots, switched with my other RAM, tested another PSU and then I looked at the CPU.

While I may have found the issue, it's still a bad outcome either way.
One pin is missing on the CPU. One single pin. I don't know how that was even possible but I must have destroyed it by accident.

There are some "useless" grounding pins on the CPU right? So there is a chance, that it isn't this pin that's causing the issue. But it seems weird to me that everything else seems to be working, fans, LED and it does make sounds while turning it on. So it could be the issue, but it doesn't have to be.

What options do I have? Order a new CPU ?

That one pin can very well cause your problem. You could try warranty if you are sure you did not break it off. They might not accept it, but.....
