Every time my computer is shut off, or the power goes out, my HP Pavilion will cease to turn on. After completing steps to get it working again, I do show a light where you plug the power to the PC, and the power light is also a white steady light. Usually, after pressing the Power button with a light, the PC will boot up. Now it does nothing at all except I can press the CD button and it will open. Other that that, no response from the pc. I need some help!!
