My PC turns on and everything is fine all the fans are running, but i get black screen which says dvi no signal, theres no power to keyboard or mouse as well, except to my usb soundcard. I tried taking GPU out and pluged monitor in, reset the BIOS , tried to switch RAMS. Sometimes PC starts but it takes like 10 restarts or so. Could it be CPU or MOBO, thinking about RAM. I got SSD and HDD but i think if theres a problem on any of these drives my PC screen would show me anyways. Im running out on options here, please help ://
