    Sounds like you've got a poltergeist. You need to take it to a store and have someone check out the all of the power cabling, clearly it's not a software issue. Could be overheating too, as a matter of fact that's where I'd start since it sounds like it has a delay powering back on. One way or another, it sounds like you need to pay a visit to a computer shop near by.


    I am competent (sp) enough to fix it just not enough to figure out what is wrong. Why would it just start overheating? I just dont have the resources to start buying and replacing parts. Computer shop wants $50 just to look at it.

    I haven't got a clue why it would start overheating, but newer computers let's say are programmed to power-off at CPU temperatures that could damage them, so maybe if you provided more information on what kind of computer it is it'd be easier to at least guesstimate where the problem might be.

    So, just apply the deduction method: a) power cord b) power supply c) wiring from power supply to motherboard c) power button (yeah, I even had one of those, was shorting and power cycling at will) d) heat

    My bet is on heat and some bad contact somewhere.

    I doubt it is a temp issue. I had this recently and it turned out to be the surge strip. Get a new one! Everytime the printer would cycle, it would create enough of a blip to scram the computer and cause a spontaneous restart.

    could it be dirty[?] might be the heating problem . do a little brain surgery and check for dust

    I think the place to start is with dirt, as jwb suggests.

    When I work on the guts of a computer, I always wear close fitting surgical gloves.

    UNPLUG THE COMPUTER, then:

    1) remove the case, ground yourself to the metal frame inside with a piece of wire (I just strip some extension cord and wrap it around my
    wrist and the metal frame) and blow the interior boards off with canned air.

    2) inspect the boards and wiring for any wires that look like maybe they aren't connected.

    3) gently shake all the obvious wire connections and re-seat them.

    4) reseat the PCBs - oops - Printed Circuit Boards.

    5) Identify the CPU - main computer chip - if it has a little bitty fan on it, using a non-conductive probe, like a pencil, see if you can get the blades to turn.

    6) While the case is off, re-connect the power cord and turn it on.

    Use it for a few days with the case off to see if it fails again.

    If you have any further questions, you can call me at 503-843-2020, or email me with your phone number and I'll call you - www.ThunderboltRanch@msn.com

    Please let us know how it works out.

    Best of luck.

    I had a similiar problem of overheating with my laptop.


    I found out that the fan/ power-supply vent was blocked not allowing it to release the heat. I solved the problem of proping it up a bit on cardborad remembering to not block the vent. volia! problem solved.

    Or perhaps yours just has too much dust in it. That would also cause it to turn off for no reason.

    Sounds like a broken power supply wire or a bad connection. I would pull and clean all of the connections, especially the power wires to the mother board. If that doesn't do it, I would replace the power supply.

    I have blew all the dust out of it already.
    It is over the airvent so I wouldnt think that it is getting hot.
    The side of it has been off for about a week thinking that it might still be getting hot but it still does it.

    When it does shut off most of the time it just starts right back up.When it done it the other day, I grabbed the power cord where it plugs into the computer, and wiggled it around and it turned on and off repeatedly until I stopped.

    There you go. Didn't GB's help after all :)

    1- loose powercord attaching to the computer.
    2- Loose connection to wall outlet.
    3- bad cord between computer and outlet.

    Simple things first. Get complicated when all else fails.
