OK then I would basically do what was posted above except I have seen some motherboards that say to not power up the computer when you try to reset the bios. If it has a jumper to reset it, set the jumper to reset and leave it like that for a few min, then switch it back to the previous settings. If you don't have a reset jumper for the bios, remove the battery (its the little coin looking battery) for about 30 mins then hook it back up. Disconnect all the cables to the drives and any external devices you might have like mouse, keyboard, usb devices etc.
Take out any interface cards you might have like network or modem audio card etc. The only thing you want is the cpu, ram and video and power it up and see if you get the anything. You should at least see the system info text aka the bios screen. Then hook up the mouse and keyboard and try booting up again. If its working at this point, then install the interface cards one at a time. If it still works move on to hooking the drives back up one at a time. This is basicly the same as what was posted above but I wanted to add the warning about not powering up when the bios is in reset mode. I use to do the same until I recently read in a Asus manual to NOT power up the system while the bios jumpers are set to the reset position. He also didn't mention removing all the interface cards and unplugging and other external devices like the usb stuff and the mouse and keyboard. Not saying there is anything wrong with his response I just wanted to justify that my answer isn't the same.
Try and kill the bios. Find the jumper next to the battery on the motherboard and move it from position 1-2 to 2-3 ... press the power button a few times. then put the jumper back to normal and give it a shot.

I would disconnect the cables first before anything and attempt to boot the system.. if it boots, then start plugging hte cables one after another until you find out what's causing the machine not starting correctly.

Good luck.
