Question new pc build working but monitor shows no signal

[ffdisk]

my build: https://pcpartpicker.com/user/PPPPA/saved/fWNvWZ

i built my first pc and everything seems to be working fine (case and cpu fan spinning, lights on case, mobo and gpu) but when i plug it into my monitor it says no signal. i know my monitor isnt the problem because i plugged my ps4 into it and it showed the display just fine. ive tried connecting the hdmi to the monitor through both the graphics card and the mobo and neither work, both show no signal. checked the hdmi cable too, everything seems to be good. help please!!!!!

Double check your RAM. Make sure they are in the correct slots and they are pushed all the way down, at both ends. If the computer still will not start, clear the CMOS and boot with just 1 stick of RAM.
