Someone gave me an eMachine tower. It turns on but I do not get anything on the screen. Everything seems to be in working order. It is only aboy 6 months old. Anyone have any ideas?

Any beeps?

Anything on the screen at all? Such as the message: "No Signal Input"?

Does the monitor LED go on? Does it go Amber? Green?

Is your graphics onboard or a Graphics card?

Are you familiar with opening computers?
