Seriously, depending on the source of the problem it's possible that the only thing getting power is the green light (but not as likely as some other issues).
Most times that I've seen this, it's been a bad power supply. Nearly as often it's been a bad switch on the front of the case. Do you have the skills necessary to test this? If not, I'd suggest that you get a diagnostic from a reputable repair shop.
The only other thing to do is to check the cables and power source. Plug a light into the place that you plug the computer in - to test that. Try another cord from the plug to the computer. Check all the connections inside of the case.

The on/off front panel switch feels ok, but maybe I can bypass the switch to test?
Is there a reset?

Some power supplies have a fuse inside of them - but be careful as the capacitors in there hold a large charge for a long time!

I'd suggest stripping the system of all parts that aren't necessary to start it up (being sure to have the system unplugged from the wall and that you hold onto the metal of the case to prevent static discharge). This is usually the PSU, the mobo, the CPU and it's cooler. It also means to remove the RAM, the CD/DVD drive, the hard drive, and any plug-in cards on the mobo.
If you get signs of life, then add the video card (if so equipped) and try that.
Then try the RAM (1 stick at a time)
Then the hard drive.
After that add the rest of the stuff (one-by-one)
If you don't get signs of life, then it's a problem with what's left - the case, PSU, mobo, or CPU.

Backup your stuff in case this happens again and you can't get it started.
Thanks for letting us know!
