标题:

No Power - won't turn on

文本:

My computer just shut down and won't power back on. Won't do anything. It is like it isn't even plugged in. I have tried a different power cord. I tried holding the power button. I have unplugged everything from the usb ports.

I have opened up the computer - I am wondering where the diagnostic led lights are. I am wondering if it is the power supply board - it does look like some wiring melted - although its not black or burnt...
