It might be a couple of things bad powersupply or power button incorrect ram module or hard drive settings ,if not then lastly have a bad motherboard which we all hate. you said you have a a green light on motherboard? Did you upgrade or install any new ram ,harddrives etc check make sure they are seated properly in their sockets and free from dust check connection on the ram module make sure it shinny brass color if not you can use an eraser to clean them. If you have upgraded check make sure the ram is compatible to your machine sometimes the wrong ram install can cause no power up problem. Do you have four green lights in the back of machine? Dell new desktop has 4 green light in back of the unit . if all four light are green then system is ok but one out of the four light are orange then you have a problem. You can go onto dell web sight for your machine to check out these lights codes. I hope this help you out some.

So the computer will not post! Try these steps.
So basically you cannot get the pc to POST. Meaning you have just a black screen when you power on the pc, right?
First off, did you attempt to update BIOS before this happened. 90% of the time this is caused by a corrupt bios.
If you did not try to update BIOS before the problem started then try these troubleshooting steps.
1. Full power down. Unplug the power cord from the Power supply. Then hold down the pc power button.
Try to boot the pc.
2. Open the case and reseat the graphics card, hard drive, and RAM.
3. Take out one of the RAM sticks if there is 2 or more. Swap the RAM sticks in different RAM slots.
4. Set the Cmos jumper to clear. Power up the pc. Power down the PC. Set the Cmos jumper back to normal position, power up the PC.
5. Unplug and replug all the power supply cables.
6. Check the powersupply function. Either by a powersupply voltage checker, put the powersupply in a different pc, or try a different powersupply in the problem computer.
That covers almost everything,,
If still nothing then possibly bad Motherboard or CPU.
