"Screw-damage"?

    Hiya.

    Hm, just finished filling up the new rig some mins ago.
    Connected all the stuff, turned it on, and just some
    secs later smoke came out from one of the bottom holes.

    Turned it off, opened it up and tried to check what's the
    cause of this.
    Looks like the screw at the bottom was somehow sitting
    too tight, connecting the mobo with the placeholder in
    the back.
    Removed the screw, turned it on again, no smoke, all
    running fine.
    Nothing damaged at all ... at least it looks like that.

    So could be a screw somehow shortcutting with the
    placeholder in the back be the cause of "buring" the
    board and furthermore, now that there's no prob anymore
    is there a damage to components by any chance?

    Thnx in advance.

    Woah.. Smoke?? :shock:

    Well, the screws are supposed to connect to the metal placeholders to provide a venue for static to discharge.

    I don't think screwing in too deeply will cause any problems... unless it forces the solder points on the motherboard to come in contact with the case. But that should cause a short circuit... and shut down the board.

    Yeah, thats what I though... o_0

    How tight did you screw it? As long as you didn't use Hercules strength, I don't think it'd be a prob. :think:

    Thnx. :D

    Ok, took a closer look now ...
    Looks like the mobo-screws coming with the case are bigger
    than usual, not much, but they are.
    It won't be a prob with the rest of the screwholes, but
    the one in the bottom-left is surrounded by resistors, so I
    think it (the screw) touched one of those.
    On both the back and front of the mobo the PCB is
    burnt just around this one screwhole, but luckily not
    elsewhere (chips and stuff are all ok).
    Just removed the placeholder to make sure nothing
    else will happen ... running fine and smooth.
    First time this ever happened to me.

    *pewh* :haha: ^^

    No risk - no fun.
    But still I'll switch this mobo with a different one soon. :)

    PS: Rig-pics will follow soon (bragging-corner).

    You actually have a Xeon processor computer - I assume that it's a workstation right? :D

    Yes, it is. ;)

    But it's not the PC I was talking about in this thread,
    the "hot" is just one of some testbeds (pics in the
    bragging-corner) ...
    Maybe I call it "Afterburner" now. :D

    PS: I would never switch case on the workstation,
    Dell enclosures are imo absolutely great.

    Swapped the board today.
    Not much to see on the front, but by a look at its back
    I'm still wondering it was functional at all ...

    Wow, that is some serious damage, and still working?

    It is, but I don't want other components to be
    damaged as well, so I won't use it anymore.

    Wow.. That's really quite serious. :shock:

    It's really odd how the short circuit occured and burnt the board. I don't see anything that could have caused it. :think:

    Me, too.
    The spacer was also burnt, the screw wasn't.
    Well, I'll never know for sure. ^^

    Hmm.. Are you referring to the metal spacer? Or those cardboard rings?
     
  14. Bestia(ry)

    Bestia(ry) Mac'ster

    The metal one.
    But I don't think it touched some contacts,
    cleaned it and using it with the new mobo
    as well and no prob at all.

    It looks like you just got a slight burn at the hole. Almost like smoke went all over the place... Is the bottom able to be wiped off clean? Either way, as others have said, you are lucky.
