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?
