The "no signal" means that the PC is not providing a signal (usually because it has not booted)
The "no signal" message comes from the monitor itself, not the PC.
You usually get one single beep on a successful boot. Is that happening?
Also, when the PC has booted, the Caps Lock light on the keyboard should toggle On and Off with each key press. If that does not happen, the PC has not actually booted.
Fans running etc do not necessarily mean the PC has booted.
