or orange light? I have a Dell Dimension 4600 PC tower and it has been working fine since I bought it in 2003. These past couple of weeks it has been working strangely. Whenever I go to turn it on the lights flash and the fan starts but then they all stop and a orange or green light starts flashing. Then I can't do anything. The power button doesn't work and nothing is on. I'm usually able to finally get it to work after pulling the power and starting over a few times. I'm really nervous this could do damage to the computer so does anyone know how I can stop this?
