Check the LEDs on the front of the computer case to confirm that the computer receives power. Plug the eMachines monitor's power cable into a working AC outlet. Press the monitor's power button. Check the LEDs on the front bezel or power button of the eMachines monitor to confirm that the monitor receives power. Orange or blinking LEDs indicate low power or no signal. Green LEDs denote a working connection.. Perform a monitor self-test. Switch off the monitor. Unplug the video cable from the monitor. Press the eMachines monitor's power button. An eMachines logo, Windows logo or "no signal" message indicates that the monitor is working properly. Plug the eMachines monitor's video cable into the video port on the computer. Attach the monitor's included DVI-to-VGA adapter to the monitor's VGA cable if your computer has a DVI port (15 or 25 pin-slots with 1 side slot) in place of a VGA port (15 pin-slots, no side slot). Press the eMachines monitor's input button to change the monitor's setting to match the computer port used. Set your monitor to DVI if connected to your computer's DVI port. Set your monitor to VGA if connected to your computer's VGA port. Connect the eMachines monitor to a known working computer with a known working video cable if the problem persists. Contact Gateway, eMachines manufacturer, if the monitor issue is not resolved. Hope this helps.

A Blinking Amber or Yellow power button means that the power supply is receiving power from the source but is unable to properly distribute it to the components. This can be caused by a defective power supply or a defective motherboard. Power supply is easier and cheaper to replace.

Most computer repair shops have a tester that they can hook up to your power supply. You can also purchase one for yourself, they usually run $25-50, it may be viable to purchase one if the shop will charge that much to test.

This could still possibly be a bad power supply, even if the fans and drives spin up. If you have a spare try hooking it up.
the list of things that can cause this are:
bad power supply
bad ram
IDE error (optical or hard drive problem)
bad card (modem, video card etc.)
bad processor
bad board
The first thing i would look for in this case is blown capacitors. Those are the little things on the board that look like little soup cans, usually with silver tops. If the tops of any of them are bulging or have junk leaking out of them, you have a bad board. If you are handy with a soldering iron you can try to replace them. Not sure if radio shack still sells caps, but they are easy to find on line. I have about an %80 success rate fixing boards in this way.
If the PS change doesn't work, then try it with different sticks of RAM, if you have more than one, pulling one at a time until it starts or you've tried it with all the ram. If not ram, disconnect the ide cables from the board, these are the wide ones usually connected to the HD's and optical drives. If it still doesnt start then pull all the cards. If it doesnt start then, try swapping processor and if still no joy a new board.
