Computer doesn’t detect RAM or GPU

[mclovinbright58]

So I built a computer not to long ago and it was working fine. After a few months it crashed on me and my motherboard is telling me it that it does not detect RAM or my GPU. I’ve replaced the motherboard,upgraded my 550 watt power supply to a 750 watt, and replaced my processor. The issue still exists! I can’t figure this out and I need help. I’ve tried resetting the cmos in all sorts of ways but nothing happens.
Processor: intel i5 7600k
CPU Cooler: Corsair h100i v2
Motherboard: msi z270 gaming m5
RAM: Corsair dominator platinum 2x8GB
Power supply: EVGA 750 watt gq
GPU: EVGA GTX 1070
Storage: Samsung 960 evo 250GB And Western Digital 1TB hard drive
OS: Windows 10 64 bit

Remove the RAM and the GPU and power up your computer. Motherboards will produce a beep code similar to the POST beep if it detects that no RAM is installed. But unlike the POST beep, RAM error beep code is characterized by long and repetitive beeps. So if you hear this kind of beep after powering up your motherboard, we could deduce that the motherboard is not dead and it is actually the RAM that is causing the problem. Another way to rule out a RAM-related defect is to try and reset the RAM stick in other memory slots if possible and try another working RAM.

Ok. So when I take out the ram and leave in the GPU it detects no gpu. But whenever I leave the ram in, it detects no ram or GPU. Whenever I take out both, it only detects no gpu
