Hello-
Welcome to FixYa, the world's largest product support community.
Most of the time if a Desktop computer turns on but you see nothing on the screen,
It may be an issue w/ the monitor or it's cable connection.
Please verify that the monitor cable is connected to the correct port. By default the Dell™ Inspiron™ 530 only comes w/ a VGA monitor port (built-in graphics adapter) at the back unless you installed a discrete graphics adapter on the computer.
If the monitor is connected to the correct port then you might consider running a monitor Power-on Self Test (P.O.S.T).
How to do a Monitor Power-on Self Test (P.O.S.T)1. Unplug the monitor's data cable, this is the cable that goes to the back of your computer tower.
If you are using an old monitor most likely you have a VGA monitor. Unplug the VGA cable.
2. Make sure the monitor's power cable is plugged in.
3. Turn the computer on.
