Question about Dell Dimension 5100 (D51L1) PC Desktop
Turned off the machine after a tornado warning in our area. Everything else works power wise in the house but my Dell. There is a green light on inside the case.
Most likely the power supply have failed. Although the system is getting some power to the Motherboard (Flea power indication on motherboard) there are at least 5 different voltages the power supply provides for the system. Losing any one can cause a no power situation like you describe.
A standard ATX power supply should resolve (It is the 1st item I'd replace, both because it is the 1st point of failure and the cheapest to replace)
Here is one ATX power supply:

Update, My (kids) Dell 9100 has a 24 pin ATX supply. PIN 8 (PWR_OK) has 5 volts. All other pins have voltages as per pinout with the exception of pin 20 (-5 volts). There is no wire from the supply for that pin.

Swimmom626Did this solve your problem??
I am getting the same thing.
I have tested the switch and the Motorboard on the Switch, also the IDE Cable that connectes the switch to the Motherboard. And of course the Power Supply.
I am thinking it is time to change the Main Motherboard??
