GT5034 has power, blue light on power button, no beep, no boot, sounds like fan running hard. Hard drive light is on for a while and both CD drives green lights flicker. Nothing comes up on the monitor. HD light goes out. CD drive green lights stop flickering. No boot up and fan continues to run. Must hold power button to power down.
