DreamPC2006 died again probably because of usb port/plug misalignment on pins.

Skybuck's Dream PC from 2006 has died again it seems.

Possible causes:

1. Static electricity discharge from either me or the vacuum cleaner.
2. AMD X2 3800+ dual core processor wear and tear of motherboard.
3. DeLock card reader short circuit.
4. Denon Receiver voltage/ampere loop back.

Cause of death as of yet unknown.

DreamPC came back alive 1 more day just like last time before ultimately
dieing.
(Symptom during death was a hearable feedback loop on speakers during
freeze, this same sound was heard on other pc when ground wire was badly
connected.
USB DeLock might have been wrongly connected at first causing a short
circuit cause damage ?! )

Most likely cause of death: USB DeLock Card Reader USB plug misplaced
causing short circuit, possible ground wire related.

Suspected damage: ASRock Socket 939 motherboard components damaged/failed
because of usb plug/port short circuit.

Blame: USB port/Plug designers.

Recommendations/Adviced for futut Make it impossible to plug in plugs
wrongly too prevent short circuits.

Bye,
Skybuck.

P.S.:

Reposting of this message, apperently google didn't post it, also cannot use
google anymore on Pentium III 450 mhz. Google has turned into slow poo.

So I cannot research this topic properly:

"Connecting USB plugs wrongly can cause motherboard death"

Typing in such a long sentence would take forever on www.google.com LOL.

Bye,
Skybuck.

Double P.S.: Don't even think about suggesting BING because I already tried
that and it forwards me to my own postings via google newsgroup which is
slow poo as well.

It's quite ensobering to see how the world turns into poo when these big
services are not working anymore !

It will be most interesting to watch the IT world come to a screeching halt
within oh say 15 years thanks to the web/HTML 6 billion crap.

Do yourselfs a favor: stick to navive executable code, and void
parsers/text/html/xml LIKE THE PLAGUE... it's slow ass poo.

Pins were like this:

.. = pin
= missing pin

+-+-+
|.| |
+-+-+
|.|.|
+-+-+
|.|.|
+-+-+
|.|.|
+-+-+
|.|.|
+-+-+

Plug was connected 1 row too high like this:

X = blocked hole on plug.

O X
+-+-+
|O|O|
+-+-+
|O|O|
+-+-+
|O|O|
+-+-+
|O|O|
+-+-+
|.|.|
+-+-+


The blocked hole did not prevent it from placing it wrongly.

I shall take a closer look at the asrock 790GX manual and post the pin
assignments for the usb port he

(It was middle usb port):

+-+-+
|1|2|
+-+-+
|3|4|
+-+-+
|5|6|
+-+-+
|7|8|
+-+-+
|9|0|
+-+-+


1 = dummy
2 = missing pin
3 = GND
4 = GND
5 = P+7
6 = P+6
7 = P-7
8 = P-6
9 = USB_PWR
10 = USB_PWR


The device wrongly attached to it was:

Do M/B USB headers not normally have a blank pin to stop you plugging it
in in the wrong orientation? Or do you mean you plugged it into another
header which was not intended for USB?

That is _usually_ right, but unfortunately there are(at least) two
different pinouts for USB mainboard connectors, and the breakout units do
not always fit. So do not rely on the manufacturers to do the thinking for
you.

for example:

The main reason for using common connectors & M/B pins is to keep the
cost of the parts as low as possible. Considering the number of them on
the M/B it is a substantial piece part cost reduction.

On the bright side, now you can spec & build a new dream-machine
