I'm running out of ideas and fast with this problem. When I turn my laptop on it displays the usual 'Compaq' logo, however after this it doesn't seem to get to the 'Windows' welcome screen. I just have a completely black screen. At this point I am not able to type anything or use any of the F keys. As soon as I then hit the power button it instantly turns itself off, I have done the hard drive and memory tests in the system configuration section on boot up and both of these pass fine. I am not able to use system recovery as when I try this on start up it takes me to the same black screen. I'm not sure whether I'm dealing with a virus, or whether I have burnt the CPU as it has had an intermittent over heating problem for the last few months. Or whether it is refusing to boot because of a dodgey fan?
