Dealing with a Dell Dimension 4700 - everytime I touch the heat sink
the computer makes a beeping noise - then I get a black screen.

Any ideas what It could be ?

    That most likely means the heatsink isn't seated properly, and when you touch it you are displacing it more. The Heatsink should allways sit very snuggly and tightly on the CPU to make sure the heat is dissipated properly. Id remove the heatsink, clean it's surface and also that of the CPU very thoroughly, then add just a tiny amount of thermal transfer paste, and then clamp the heatsink firmly into position.

    I agree with Rindi, but I'm curious as to why you're touching the heatsink while the computer's running.

    it should not beep in the scenario described; therefore i assume there is someting touching the heatsink - so check it for touching parts.

    Or--> a loose pin on the CPU. Bad CPU socket on the motherboard.

    I agree that it shouldn't beep, but I'm still curious why somebody would be poking around inside the case when it's powered on. I've done it before myself, but it was because I was troubleshooting something else. Is that the case here? If so, it might be related to this problem, so it would be good to know. :)

    To look for overheating parts.
    A very common diagnostic technique.

    That's exactly what I was thinking. What prompted this in the first place? Knowing the symptoms that made Jetsonx open up the PC and start prodding around might help us understand why it beeps when the heatsink is touched.
