I have a MSI 785GT-E63 motherboard. Up until 2 days ago the computer worked perfectly. Now it will not power.


I thought it was the power supply so I have tried 2 new Power Supplies with the same result. When I replace the power supply and push the power button the processor fan moves briefly and then nothing. 


I have reseated the ram and the processor. I have pulled the video card. I have disconnected the hard drive and dvd. I have pressed the reset rom and power button on the motherboard. I have reconnected the cable that connects the power button to the motherboard. 


Still the same. 

What could it be?

Remove all the devices, DVD drive, HDD's, RAM, Graphics cards, etc. etc... So there is only the power supply hooked to the motherboard.


Turn it on.... Still nothing? Then the mobo is faulty.


If you get POST beeps restore the hardware items one at a time (starting with the RAM) until the symptom shows up again... the last restored device is your problem.
