    First, try unplugging the power supply and removing the board battery for a few seconds. If that doesn't work, you will have to search ebay for a replacement board. You might also change the power supply if it's more than 3 years old. The HP windows operating system will only work with an hp board; doesn't have to be the same model unless your neighbor didn't make back up copies of windows. Many of those boards ship from China and are used, but new is too expensive.

    Thanks oldie< Had a feeling i was gonna hear that. Replaced video card and memory this morning and didnt work. pulled battery for a full minute as well as power supply plug, i also changed power button from my hp luckily was the same bbut again didnt work. noticed slight powdery residue at cpu socket and figured it was the board. thanks again for the reply!
  3. Unfortunately, vacuum cleaners generate static when running so he most likely killed that board the second he touched the board.
    Personally I prefer to use a compressor and nozzle....but you'll want to do that outside as the dust bunnies will be flying out of that case!
    Good luck on your mother board hunt....JQ
