So I recently built up a new computer, and I can't get it to post. I have a new mobo, memory, and CPU. Using my old GPU, PSU and HDD, so I know those work. I can get 1 long, 2 short beeps when I only have CPU in the mobo and HDD plugged in. But when I plug the RAM back in, I get nothing. No beeps at all. I've spent the better part of the day building this all together, and yes, I've already breadborded it. I couldn't figure out the problem there. Maybe I didn't do something right? Any help would be great.

New Components:
ASUS Z170-A mother board
16gb of G.Skillz RAM at 2400mhz (2x8gb)
Cooler Master Evo 212 heat sink
Intel i5-7500 CPU
NZXT H440 case (if you wanted to know)

Old Components:
Gigabyte R9 390 GPU
Seagate 1tb HDD
Corsair CX600 PSU
***all of these worked earlier today on my old build***
