It is always good to give some information about the case with your question, like if there was a power out, strange noise from the computer or anything that might suggest or assist helping you.

try this:
1. Unplug the power cord
2. Press the power button several times
3. Plug the computer back in to the power outlet and try again.

If it fails, try to open the side of the computer,
Check to see if when connected to the power outlet, you can see a led on the Motherboard turning on.

It might be that your PSU is dead.

Camera wont turn on&lens wont move


Folks,

Try to assist the machine mechanism. Turn the lenses (force is no necessary) when turning on or off. This should unlock the mechanism.
Good luck!

Fixed amber light - start,shut down itself and restart itself Hello, Yesterday morning, I have installed a second screen linked to my graphic card. I tried to install a 3rd screen on the VGA motherboard, and it didn't work so I take it off. I could work on the computer with the 2 screens all day long. I left my office and the screensaver started. When I came back, I couldn't started my computer and my screen didn't light on after moving the mouse or writting on the keyboard. Then, I shut down my computer to restart it. Here is the problem. 1) The power light was fix and amber, the ventilation works. 2) 2-3 seconds later, it shuts down itself for few seconds 3) And it restarts itself. However, I still have the fix amber light and the screen is not activated. I checked the wall plug, I reduced the number of device on the trailling socket. I removed and reinstalled from the motherboard the RAM memory card and my graphic card. I tried with only one screen. But I still have the same problem. Do you have any ideas about what the problem could be: - Is the motherboard over? - Is the graphic card over? - Is the power bloc over? How could I evaluate which component is not working correctly? Thanks for your precious help. My configuration : - Intel Core 2 Quad Q8200(2,33GHz,1333MHz,4Mo) - Windows Vista - Cordon d'alimentation : Européen 2M - Carte graphique : 256Mo DDR2 ATI Radeon HD 3650 (pleine hauteur,sortie DVI/HDMI/DisplayPort,Double affichage)
