Either a failed PSU or motherboard.
Is the power button LED, Steady Blue, Blinking Blue, Steady Amber, Blinking Amber?
Are there any 'Beeps', or error messages, if there are, please post the exact text of the message?
No there are lights on the unit. All again that happen is when i plug in the power supply is that the green light on the supply starts flashing. I push and nothing happens. No lights beep or anything. I am a little embarassed because i am a dell warranty tech but can't find any tech specs on this model. If you can give me insite on the power supply with the green light flashing that would be great. No lights or beeps it is dead. Just again the green light on supply flashing when plugged in
