No picture on boot

[TheKingOfGaming]

I'm building a new pc, with a ryzen 2600, b350 tomahawk, 8gb of 2133mhz ram, and an r9 390x. The problem I'm having is that I don't get picture on boot, nothing shows up on my monitor. The motherboard itself is an open box one from microcenter, which is 'guaranteed' to work properly. When I turn the computer on, none of the debug leds light up. I should also mention that my case is old, and for some reason my computer only boots when i press the reset button. As a side note, the motherboard didn't come with cpu cooler standoffs anyways, so I'll probably return the motherboard at some point, but I just want to at least figure this out before I do anything. Edit* the graphics cards fan spins and so does the cpu's. It seems like it's all fine, but their isn't any picture.

I would suspect the PSU immediately, especially if nothing is lighting up.

 

Try a different unit, or try the unit you're using in a different rig to see if the results differ.

All the fans spin, and the msi logo on the graphics card lights up. The motherboards red light works as well.

The b350 mobo doesnt support r5 2600 without a bios update. Return the mobo, and get a b450 tomahawk instead, it is much better.
