HELP - PC Wont POST

[redhammer]

I have been going nuts trying to figure out why I can't get my PC to POST. I have slowly swapped out part after part thinking it would fix it to only to find that it still won't POST after replacing every part..

 

What am I missing? I've built multiple computers before so this isn't my first, just the first time I've had such a problem. 

 

- CPU: AMD Ryzen 5 3600

- Motherboard: MSI MPG B550 GAMING PLUS

- RAM: Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz

- PSU: Corsair CX750M 750 Watt 

- GPU: PowerColor Red Devil AMD Radeon RX 5700 XT

 

I have been trying to strictly get it to POST with just the mobo, cpu, ram, and psu so there is nothing else attached (not even the case). I can't for the life of me figure out what is going on. Like I mentioned, I've swapped the motherboard, cpu, and ram for new parts thinking one of those was DOA but nothing worked. I also tried using a different power supply that I know works to see if it was my current PSU, but it sill did not POST. I've literally replaced everything so I'm at a loss at what to do next? Could there be a compatibility issue that I'm missing?

Are you certain the mobo supports your CPU out of the box?

You can't post without a graphics card. That cpu does not have integrated graphics.

I am having a similar issue with my B550 but i have DRAM LED error on mobo, does yours have that as well?
