1) Disconnect the Power cables on the back of the unit and press and hold the power button on the unit for 30 seconds then remove the Side panel disconnect the Hard drive & Memory in case you have 2 or more sticks then try 1 stick at a time connect the Hard drive and see if you can get any display.
2) If that does not works then remove the CMOS battery which looks like a coin wait for few seconds then insert it back on again please note the + symbol should be on top side.
