    My Quicksilver 867 shut down this morning, on it's own and the power
    button won't work right.
    I've been able to get it started a couple of times by pressing the power

    button but the machine will shut off after a few minutes., then the
    power button won't work again for a while.

    There doesn't seem to be any pattern of when it will start or not. When
    the machine does start up it boots OK and everything works fine
    softwarewise, but then it just shuts off.

    Before I replace the power supply, has anyone had similar problems, or
    other suggestions?

    That was my first thought, but I haven't been able to start it for hours now

    I don't know how to test he power supply to see if that's the problem.

  3. You'd get better results with a volt meter. The ohm meter might blow up
    while checking voltages. :)

    I had the same problem twice on a 2x800Mhz in the last 4 months. Shitty
    power supplies, first lasted 18 months and completely died, second one was
    funky right off the bat and exhibited behavior like yours (at first I
    thought it was an overheating problem).

    That would really make my day, eh ? .:)

    Where would I stick the probes from a volt meter to check the power supply ?

    Must have been a Freudian slip. I know where I'd like to stick the probes :)
    I'm still not sure how to check the power supply. My volt meter has 2 probes and
    I'm not sure which ones to put where to make it work.. The connections have so
    many pins. Someone suggested checking the fuse on the power supply, but I'm not
    sure where that would be located. I've tried everything else I can. I reset the
    cuda, I put in a new battery, I took out the battery for an hour, I reseated the
    Ram, the video card, every connection I could, I sacrificed a chicken, I changed
    my daughter's name to Steve Jobs, I renamned my dog Steve Wozniak, I made a Bill
    Gates dummy and pelted it with apples. Nothing worked, (but I feel much better

    So I gave in and just ordered another power supply. I hope this works.I hope I
    didn't mess things up more by trying to reset everything. (like the cuda) If the
    new p/s doesn't work I'm gonna have to buy a new machine. :-(

    Thanks for all the help.

    It'll be fine. I did the same stuff and it was simply the power supply.

    With modern Voltmeters it polarity really doesn't matter. If you connect
    Thanks !! That's very helpful. I just tried it. I was able to hold the black probe
    down on the chassis ( I wedged it into one of the mounting holes in one of the
    expansion bays. I put the red probe in each pin of the connection. I got no
    indication of voltage at all. (Just a beep, but the voltage indicator didn't move.) I
    tried the power cord and it was in the 120 range. ( I also tried it by putting the
    black probe in the black wire pins and the red in the colored pins and still got no

    I tried it on the 2 motherboard connections (P1 and P4) and the expansion connectors
    as well. Nuttin'

    I'm having high hopes for the new PS.

    I appreciate the input !

    Well, I replaced the power supply today and my machine is up and running again ! (at
    least for now.)
    I'll keep an eye on the PRAM battery, but so far so good.

    I'm glad I didn't just bring it into the local apple store and let them have it for
    a week. I think I saved a bunch of money by doing it myself.

    Thank you to everyone who took the time to reply.

    Kind thoughts,

    Hi Gang,

    5 days since the new power supply and so far everything is running like
    it should. USB devices, firewire device, everything.

    I hope this info saves someone else some time and money.
