"Screw-damage"?

Bestia(ry) · 30th Mar 2007, 10:59 PM

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??

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.

woah..!!!!

After smoked... still can work... u r really lucky...

Cross my finger & my heart...

Thnx.

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*

^^

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?

Bestia(ry) · 31st Mar 2007, 12:35 PM

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.

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?

Bestia(ry) · 8th Apr 2007, 09:50 PM

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