Do the fans inside the case spin?
If so, then the computer is getting power.

If you have an older computer, with a Pentium 2 or Pentium 3 CPU, it's possible that the "slot-mount" CPU has been dislodged from its "slot" socket. Turn the computer off. Disconnect the AC power.
Make sure that the CPU is properly "seated" into its socket.

Hi,
If you are referring to the green light on the system tower and is blinking the problem could be the system is in stand by mode.

Turn off the computer by pressing on the power button on the system tower for 10 seconds.

Disconnect the black power cord at the back of the system tower and then again press the power button on the tower for 10 seconds. There would be no activity on the tower when you do this.

Reconnect the power cord and then power on the computer to see if the issue is resolved.

How's the status light of your computer monitor? is it blinking amber? and the status light of your computer tower's power button? blinking amber as well or solid green or no light at all?

1. Disconnect all the connection at the back of your computer tower
2. Press the power button of the computer tower for 15 seconds
3. Reconnect the power button and the monitor cable at the back of your computer tower and turn on the computer (if it turned on that means that one of the device plugged at the back of your computer tower is faulty)
4. If still the same problem, open up your computer tower.
5. Reseat the video card, Reseat Hard drive, Reseat Memory, Reseat CPU, Reseat power cord coming from the CPU to your computer (doing all things one-by-one to pin-point the root cause of the issue)

If none of the troubleshooting steps fixed the problem, possible that the power supply is faulty and if the power supply is faulty sometimes it goes with the motherboard.

There could be a hardware problem on the computer if the power button led light is "Orange/ or amber", if you can open the computer, try removing one memory card at a time and see if the power button will change.

My tower will not turn on


It sounds as if your power supply is having issues, I would recommend replacing it.  If your good with computers, you can test the power supply: 1. Open the computer tower. 2. Find the main plug which runs from the power supply to the motherboard. 3. There should be 16 wires. 4. Find the green wire, short it to the black wire with a paper clip. 5. If the computer seems to turn on, its your motherboard having issues and you will probably need a new computer.  If it does not turn on, your power supply has failed, and you need to replace it.
I hope this helps!

Remove the power supply after everything is unplugged and take it to your nearest electronics store. They should have a tester there. This is probably the problem.

My pc light flashes green


need to know the model # and type of computer? Remove all external devices except mouse, keyboard and monitor. If not getting any power at all, could be your power supply.
