Hello, my Dell won't turn on. The green LEd on the Motherboard is on, but NOTHING happens when I hit the front panel power switch. I checked the switch with am ohm meter, but it is okay. The PC is just dead apart fro that litle green LED on the motherboard.

I am assuming you are trying to power up an installed motherboard, based on the category selection. You say that you have power connected. That means that you have connected the 20 (24) pin main connector and the 4 or 8 pin CPU power connector to the motherboard. Have you connected the front panels controls to the motherboard header? There are connections for the power switch, power LED, HDD LED, reset switch (optional). They must be connected in order for the motherboard to start. THe HDD and Power LED connections are polarity-based, so if you hook them upo backwards, their respective LED will not light. The HDD LED plug is usually red and white with the red being on the positive (+) terminal. The Power LED plug is usually green and white with the green wire going to the positive terminal. The power switch and reset switch wires can be connected either way as they are not polarized.
Faulty motherboard or power supply. Best guess is a fault in motherboard causing excess current and it then shuts down. Try unplugging all peripherals except for graphics card, including the drives. If still nothing, try a different graphics card, different power supply. If still nothing, try a different m/board.
the front panel header configuration of that particular motherboard.
6-8 (red) is your power sw 2-4 (green) is your power LED 1-3 (yellow) is your HDD LED 5-7 (purple) is your reset sw black is not connected
The motherboard should go into a custom case no problem.
