Question RAM and case lights on, monitor no signal

I built a pc from scratch starting last night at 5-6. I finished building the pc at around 9-10 and went to sleep. I woke up this morning and turned the pc on and the only things that came on were the lights for the RAM, case and motherboard. Only my top fan was running. When I went to plug the hdmi cable into my monitor the monitor said “no signal.” I looked on several websites to try to fix this problem and nobody has the same problem. PLEASE help me, I have been troubleshooting for 7 hours today.

if only one fan is spinning, then either other fans aren't connected properly, or something else isn't plugged together properly.

can you tell us your hardware please?
Need make and model of each.

Motherboard

CPU (including if you have 3rd party cooler)
GPU
Case

Extra connectors of some kind for fans or other hardware

ok.
so to clarify, you installed the cooler onto the CPU correctly I assume.
you didn't specify if the RAM you have is a dual channel kit, but with RGB I assume it is.

Make sure the RAM is in the correct slots for dual channel on your board.
Some boards it's A1+B1, and other's it's A2+B2. Refer to your motherboard manual.

Make sure you are plugging the video cable into the GPU and not the motherboard.

Double check the power connectors for motherboard, CPU, and GPU and that they are all there, and firmly plugged in.
