Desktop 590-POO4 I3
Working in Excel and screen went black and now screen shows power light and "no signal." Tried to push pc power button and no light or fan noise. Unplugged pc and when it is plugged in I can hear a faint noise inside (not the fan). Checked all connections and power supplies. Attached monitor to another pc and monitor works there. I think it has power because I can hear some quiet constant noise, just no power or light. Thanks for any thoughts.

@babywinston -- something inside your computer has failed.
Since you don't seem to be a computer technician, it is time to take your computer to a qualified computer-technician for trouble-shooting, such as trying a different power-supply.
