Hi everyone,
I bought the ASRock b450m pro4 two days ago. However, i'm experiencing some issues. I can't get the motherboard to post.
There's no indication that anything is wrong besides the fans not spinning. I read that some motherboards won't do anything (including spinning fans?) when there's no CPU installed, which is the case here. My CPU, the AMD Ryzen 7 2700 will arrive in a couple of days. Does anyone know if that is the case for this specific motherboard? I was also struggling to figure out how to connect the system panel connectors.
Here's what I tried:
* Jump started the PSU, that worked
* Removed the RAM sticks
* Plugged all power cables, including the cpu power cable, into the motherboard
* Tried to jump start the motherboard using a screwdriver
* Removing the battery from the motherboard and putting it back in
* Getting the motherboard out of the case to make sure nothing is shortening it
I also checked for visible damages, but the top and bottom seems to be completely intact. Not sure what else to try here. Any help would be seriously appreciated.

So you are trying to run your motherboard without a CPU in it? Perhaps just wait for your processor .. install it .. and then see what it does.
