Just finished building a pc, connected to a working monitor with a vga cable. Pc turns on (lights and fans turn on) but no display shows on monitor. The monitor recognises that it is connected to the pc as when I unplug the cable from the motherboard a window comes up on monitor saying cable is not connected. I’ve tried everything and can’t seem to find a fix and desperately need this running
 
This happened to me a while back. My issue was, unfortunately, a fried motherboard.

Your issue may be different, but in my case, everything lit up and fans spun, but nothing actually showed up on the display. Changing motherboards fixed this for me.
