Question about PC Desktops
When I press the power button, the fan runs super-fast constantly, nothing on monitor (as if no connection, tried different monitors), CD-ROM and HDD lights stay on steady. [here's a little history] A few months ago, machine would have same problem randomly while in use. It seemed that if you let it sit for 10-15 minutes, everything would be back to normal and problem wouldn't occur for days or weeks. Problem got more severe, thought it was a temperature or temperature sensor problem. Opened case and blew out dust and reseated processor and RAM, problem disappeared for about 6 months. Mother-in-law blew circuit breaker with space heater, blow dryer, TV and other random things, that's when the computer starting to refuse to start with fan running high.
Giving the fact that your fan is constantly running and you had an electrical spike you should take it in to be looked at. If it overheats then the motherboard will go and it will cost more to fix it than to buy a new one.

It is the power supply. EMachines have a long history of using cheap power supplies. I have replaced over a dozen EMachine power supplies with a 100% success rate. They are easy to replace and can be had for less than $20. Just write down the model number and take that to a computer parts store or remove the power supply and take that with you. Steve

you plug in the power cord is there any lights whatsoever on the laptop, where
the plug goes in or on the AC Adapter of the power cord?
When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the computer is trying to boot or may have booted, but the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the laptop and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.
your memory is bad or the memory slot is bad.
the Power Cord, Open the Case and remove one of the memory chips. Set the
chip aside then try rebooting the computer. If it boots, then you know
the memory chip you set aside is bad so mark an x on it with an ink pen.
If it fails to boot then move the chip to the next memory slot and try
rebooting. If it fails take the chip out and set it aside, then put the
other chip in and try booting it in both slots. If it boots, just to
verify that the chip set aside is bad, mark an x on it and put it into the open
memory chip slot and try booting.
