He may need to open the casing to make sure the video card is firmly in place. Turn the power off, unplug, press the power button to get rid of any extra juice. Make sure you're grounded and open the left side, computer front is facing you, and look inside.
Look where the monitor cord attaches, is the card firmly in it's slot? If it is, place the card in another slot of the same size, screw the card in place, close the casing, plug it in and see what happens. If it STILL won't run then I think the video card or the monitor may have been damaged.
If there is no video card then it may be the monitor was damaged.
