Cable not connected - monitor message, restarting the PC then it works fine

[raul_is_forfree]

Hello to all of you. I'm new here so I'll try to give you the exact details about my issue.
I have recently added a WD 240GB M.2 SSD to my PC, installed the OS on it and when I'm turning my PC on it says 'Cable not connected' on my monitor, which is actually connected. If I'm restarting my system from reset button it works just fine.
My build is the following
CPU: AMD Ryzen 1500X
MB: MSI B350 PC Mate
SSD/HDD: WD GREEN 240 GB M.2 and Seagate Barracuda 2 TB HDD
GPU: Sapphire RX 570 4GB
RAM: Crucial 2x8 GB DDR4 2400 MHz
Monitor: Acer RQ220H 21.5" connected with HDMI
Is this issue related from the GPU or from the SSD?
My BIOS version is the latest from MSI site
And the EZ_DEBUG LEDs are turned off when screen is with that message

Did you hook up the PCIe cable from the PSU to the GPU? Typically that is what that error message means. Make sure it is plugged all the way in on the GPU and the PSU if you have a modular PSU.

Yes everything it is plugged in order. The only thing is that after I reset the PC it boots normally. Just at first boot is showing that message

Try clearing the CMOS. Remove the battery from the mobo for about 10 seconds. It is round and about the size of a quarter. That will reset the bios. Typically it is used if you changed a setting and cant get the system to boot. So there may be something there that needs to be reset.

ok, I'll try doing that and I will come with the result

Unfortunately reseting the CMOS doesn't help
