As the diagnostic lights are not lite and there are no 'Beeps', sounds like a bad motherboard.
If you are comfortable working around computers, you could try the following:
Note: The only 100% method of testing a PSU, is to install a know working power supply.
Unplug the cord from the power supply, hold the power button in for about 15/20 seconds, open the case, unplug the 24-pin power connector from the motherboard and jump the Green wire to one of the Black wires, reconnect the power cord and power the system, if power supply's fan and the hard drive runs, then the PSU should be good.
Note: Do not remove any wires from the plug, use a small piece of wire or a paper clip as a jumper.
Power supply checks out and the system still does not work, again remove the power cord, hold the power button in for several seconds to discharge the residue power, reconnect the 24-pin connector to the motherboard.
Remove all the PCI cards, the video card [if applicable], memory, all peripherals, disconnect the data and power cables to all the drives, check that the front panel cable is connected to motherboard, with nothing else connected to the system, reconnect the power cable and power the system on.
If you do not get any beep codes and/or there is no change in the diagnostic lights, then it would appear that the motherboard has died.
While the case is open, check the motherboard for capacitors with bulging tops or are leaking, the tops should be perfectly flat.
thanks a lot for the lil test i learn something new i guess i have to buy u new mother board u have any one in mind u think i should buy or a up grade or better one
As the Precision 380 supports a BTX motherboard and as both the case and motherboard have proprietary features, the only motherboard that would fit the case would be another Precision 380 MoBo,.

Is the Yellow power LED, blinking or solid?
Are there any 'Beeps'?
For more info, check the reading of the four diagnostic lights on the front panel
