I turn on my desktop computer and it starts for a second with the fans then stops. The mother board has a steady orange light on it. I tried a new larger power supply and and had the same issues. I unplugged all components and replugged them in and still nothing. I ruled out the power supply, connections....any further suggestions? I'm thinking in may be the motherboard or the chip not cooling properly, but have a lot of fans in the case (6) and have have a coolant fan in there as well...so thinking that the motherboard might need replaced and rebuilt. Any suggestions would be great!!
