Can some one help me ?

Check the monitor plug that goes to the computer for bent pins. Try another monitor. Disconnect all devices from the computer except the keyboard and monitor. Make sure the display adapter is fully seated. Look along the side where it plugs-in. Reseat the memory, and disconnect all drive cables from the motherboard. Try another power supply.
