I would try shutting down the computer in the normal way, and turning off the monitor.
Boot up and turn the monitor back on.
If it still doesn't work, then I would check the cables and power plugs and wall plugs.
Check the mouse and keyboard cable and any other cables plugged into the computer.
The next step requires a seperate monitor or laptop.
Try unplugging the monitor and pluging in another monitor. Most laptops have a common
VGA adaptor jack or even an Svideo jack.
If the other monitor does not work, Then take to a qualified technician for repair.
It could be your power supply in the computer or video controller.

I hope this was useful and please comment if this was helpful to you.

> won't turn on

Remove the side-panel, and then press the ON button.
Do any fans start to turn? Feel any air coming out of the back of the power-supply?
Does pressing the button open/close the CD/DVD tray?
If not, then your power-supply has "blown", and must be replaced.

If the fans do turn, and the tray opens, but nothing happens on the screen,
e.g., no "splash" screen, nor any brief white-text "hardware-summary" appears,
then it's either the CPU or the motherboard which is the problem.

If you see the "splash" screen, or that "summary" screen, but Windows does not start to load, then the disk-drive either is not getting any power, or its "data" cable is not connected, or the disk-drive itself has "died".

It's time to take it to a qualified technician, for professional trouble-shooting.

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.

it seems to be an issue of a loose Hard drive connection.. you can open up a tower and re-connect the cable.

Sounds like the monitor is not getting a signal from the tower.
Do you have another monitor/LCD screen that you plug into your tower? That will tell you if the LCD is the issue or the tower.
If it is the tower that is at fault, then you need to try and figure out if your video is separate from your motherboard. Hopefully it is separate, that way you can get that replaced. If not, then it means that your video card is integrated onto your motherboard which is much expensive to get fixed.
Hope this helps.

It is possible that the power box is dead.
Or try this open your box and disconnect the power supply from the mother board and put in beck. And try and boot up.
