Hello.
I have just put together a new pc.
I think i have done it correct.
When i try to start up it lights up the motherboard and the fans start. It do not get any picture on the screen.
The HDMI cable is connected to the RX 590. I have not tried to connect the HDMI cable on the motherboard output.
I have not tried to reset the bios on the board.
I have not uptdate any bios on the board.
The screen is working (use it with my old pc with HDMI cable now).
I tried to install Windows 10 Pro on the M.2 SSD card (no other HDD is connected)
I have 2 cd/bluray drives connected on Sata cables to the board. These 2 drives is the only thing that is old in the pc. All the other components is new.
Anyone have any idea what is wrong?

With regards

With your system breadboarded, with only the the CPU, motherboard, one stick of ram, GPU and the SSD see if you get any display on your screen.

Due to your processor lacking any iGPU, you won't get display from the motherboard's onboard display connectors. Do you know if you've got the latest BIOS update on that motherbaord? You should've gone for a B450 chipset board since that'd have been cheaper(for most people worldwide).

Try and source another PSU from a friend or neighbor that has at least 650W of power for the entire system and is made by a reputable brand.

Hello.
Have tried with an old (but working) CPU 750w and it is the same.
The motherboard lights up and the fans spins but it slow down the fans after some seconds, but the lights is still on on the motheroard.
I have tried to reset the CMOS and take out the M.2 drive. Have also take out one of the ram and tried it on all the 4 places on the board.
Have let a computerstore have a look at the pc and they think that it is faulty motherboard or the CPU.
What du you think? Should i return the board and CPU?
With regards.

you might have to borrow a 1000 series ryzen to test it
ram can also cause a mobo not to post so test a different ram as well
good luck
