PC won't display anything. And no lights on keyboard or mouse

[Outspending]

I just built a brand new PC. And it turns on but doesn't display anything.

 

Specs:

Motherboard: B450M 

CPU: Ryzen 5 4600g

GPU: GT 1030

PSU: 600W

 

Can anyone help please..

 

I've tried to put 1 ram stick in one at a time.

Checked all connections.

 

But still nothing

Try connecting the HDMI/VGA/DVI/DP to the motherboard instead of the GPU, see if the CPU and board are functioning. If yes, double check the GPU, psu connection, reseat the GPU.

The b450m says it's compatible with ryzen 4000 gen if I update bios but I can't flash it. And I took it out of the box. Can I return it?

Why can't you update the bios?

Well I can't get a display. And I can't flash bios onto that motherboard I don't think. I've tried to google it but everytime it's the wrong board

Might be helpful to others if you mention which board model you have?

Is there anyway to fix this? I rlly don't want to spend another $200 on a cpu

Frankly speaking I have no clue about this, though people seems to say that you need a boot kit from AMD which is a cheap AMD CPU just to setup the BIOS. Might want to post another thread for this specifically.
