Re: My computer won't start up
It could be that your motherboard has decided to give up and die. Before we stick to that idea though, try unplugging your monitor and plugging it back in (just in case).
Also I know you dusted, but make sure you remove most if not all of the dust from on and around the motherboard area.
Have you had any other problems like this or has this been a once off?
Whoever appeals to the law against his fellow man is either a fool or a coward. Whoever cannot take care of himself without that law is both. For a wounded man shall say to his assailant, "If I Die, You are forgiven. If I Live, I will kill you." Such is the Rule of Honor.
