DRAM LED on - tried with brand new RAM, no dice

[flavor8]

I have an Aorus H370 motherboard, brand new. When powering up, the DRAM LED comes on, stays on, and then after 10-15s the motherboard power cycles.

 

I tried purchasing brand new RAM, with the same result, so it's not the RAM itself. I've also tried booting with no RAM - same result. I've also tried seating a single RAM card in each slot, with the same result.

 

Have I missed any steps or should I return the motherboard?

 

Thanks

Could be motherboard or the CPU may need to be reseated. If the CPU pins aren't making good contact it can still work but will register memory or other issues. I would reseat the CPU first. What are the full specs of the computer?

I have a Gigabyte GPU also, but it's not installed yet.
