    Your CPU inside your computer case, has a metal cooling Heatsink on it, and on top of that usually sits the CPU fan

    Between the CPU and the Heatsink is a paste called thermal paste (actually there are a few names!) This thermal paste can be purchased from computer retail stores, or even online, the best of the best compound is Arctic Silver

    Anyway, by cleaning the old thermal paste from the CPU (ideally using "isoprophyl alcohol") you then re-paste the CPU and then re-mount the Heatsink and fan

    Actually this is all discussed in the link above
    If you are unsure on doing this, at least follow the "No Post" link

    If qualified technicians have told you the motherboard is bad (after testing it I hope)
    Then that's that

    But many times these technicians don't thoroughly test the board (which would take hours!)

    To test the board, they must fully remove it from the case, then plug in a new CPU and new Ram (for testing purposes only, and to eliminate those parts too)
    Plus they must remove all dust, and then at last test it. (Hours later!)

    Unless they viewed the Motherboard, and saw that the Capacitors (we call them "caps") were faulty (ie balooning up in physical size) which would take about 10mins, to prove the Motherboard was bad

    Incredible

    I would have said it's free, ie I didn't fix it (nor did they)
    Possibly why I'm very poor !

    Anyway, if you are brave enough, remove the side cover (we are talking PC aren't we?) Make sure all power is off, and don't touch anything inside (due to anti-static issues ONLY)

    And then check the CPU fan is not full of dust
    And check the "caps" are not curved upwards (linguistics?? What's the word I'm looking for?) The caps should be flat on top (there are many caps)

    Domed

    Does that sound like the best word?

    The caps should not be domed

    I always thought it was "domed" ... hang on MS Word 2007 might help with synonyms



    "domed" is correct :)

    Anyway, did you look?
