Do you hear a whirring sound when you press your power button? Is that sound located toward the back of your computer? If so your power supply may be ok and your motherboard has failed. If you do not hear a whirring noise then your power supply has failed and you'll need a new unit. Take it in to a repair shop or replace it yourself.

    Ok well as odd as that sounds it's a good sign. You'll still need to have a hardware repair but it should cost between $70-$140 depending on the size of your computer. You only need to have your power supply replaced and it sounds like your motherboard should be fine.

Hi. My Emachines PC is having major problems. At first it wouldn't start, when you pressed the button on the middle of the computer it would light up, then read no signal, and shut off. When I unplugged it...


try this...
  • Unplug the power cord.
  • Remove the battery and hold the power button for 30 to 60 seconds.
  • Re-connect the power and attempt a boot.
  • Shut down, put the battery back in and you're good to go.

Dell PC will not boot


Hi Doug, Please try to boot your pc in safemode. To get in safe please press F8 and hode while booting your computer. If it will boot to your desktop. Its like your driver was corrupted. Try to uninstall your drivers and try to boot again. If your problem still persist its like your windows system files was corrupted. You can try to fix it by booting to your windows installation cd, you have options their to repair your windows. Let me know if its your problem still unsolved. Goodluck

Aux power led light is amber on dimension E521


I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

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 laptop 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 computer 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 your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

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.

Maybe your memory is bad or the memory slot is bad.

Remove 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.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.


Below are links and info I found from Dell's Website based on your model.

Getting power but wont boot up or anything


pull out everything in the computer except what's required to boot...so any pci cards or video cards (if you have onboard video). you can also try pulling out the ram (while unpowered AND unplugged) and then booting to hear beeps...if you pull the ram out and the computer doesnt make a sound, its probably a bad motherboard and needs to be replaced. if you hear beeps, try replacing the ram or disconnecting other parts...like harddrives, optical drives, modems and what not.
