Happened to me today. I took my graphics card off, Took all cables off , did a vacuum inside my CPU , plugged every thing back in.
Still no display.
Then i took off my GPU again made sure it fit firmly and nothing was loose.
Also make sure your VGA screws are tight both connecting GPU and monitor.

Hope this helped.
