The problem is your power button needs to be replaced or you can buy a new pc box on ebay for cheap.

Computer wont turn on


Make sure the tower is getting power. There will be a green light on the back of the tower where the power cord goes. Make sure the cord is snug and that it is securely plugged in to your power source - I'm hoping it is a power surge strip and in which case, make sure the surge strip didn't get unplugged or turned off. If you have it plugged directly in to the wall then make sure that outlet has power by plugging something else in to it that you know works. After doing all of this, make check to see if there is a light on the back of your pc. If not, unplug the power from the back of the tower, wait 30 seconds at least, and then plug it back in. Hit the power button on the front just once, if it doesn't power up, press and hold the button in for a 2 seconds and release. If that doesn't work, your power supply may have gone bad. That happens from time to time. Good luck, hope this helps!

I recently moved, my computer tower was working fine before i moved it, and now it doesn't even turn on. i've tried different plugs and when i looked inside it, a green light is on, so it is apparently...


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.

My vostro 200 slim tower wont turn on PLZ READ FULL


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!

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.
