Moniter wont display anything

so i upgraded my pc only by putting in new fans, rgb ram heatsinks, led lights, new case and thats it.

Everything on my computer works fine, the fans move, the cpu fan moves, led lights on, case power on, gpu working; everything works. However, when i plug in my vga with dvi-d adapter to my moniter it doesnt show display on moniter. I even tried connecting my vga cable from the moniter to the mobo and nothing...

Strangely if i disconnect the vga from the moniter, it says no vga detected... but if i connect the vga to the gpu or mobo port, it then turns on the moniter and the moniter says “Entering power saving mode” then it cuts off.

-keep in mind my hdd was wiped because i was going to upgrade my pc and mobo previosly but i think my mobo wasnt updated with the latest ryzen bios because my moniter also wouldnt boot in to bios or display anything (much like whats going on now) so i switched back to my old cpu, which is giving me the problem now. I also switched the mobo battery and reset CMOS but nothing...

all help is appreciated
