Did you check your monitor cable by switching it out or replugging it in?

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.

The three beeps could possibly be some sort of error code. Try looking up your computer's model number and checking the manufacturer's site for any documented issues.
