Question PC NOT GIVING SIGNAL TO MONITOR OR ACCESSORIES

[renep05]

Hey, a couple weeks ago my pc started having this problem where the actual machine turns on, but nothing shows up on the monitor and it says no signal from HDMI, also neither the keyboard or the mouse light up. In order for the pc to start working properly and actually showing up on the monitor i have to spam on and off multiple times until i get lucky. PLEASE HELP

I have tried resetting the cmos
changing the graphics card
reseating the ram
new hdmi
new monitor

Nothing to suggest without system specs.
