Mysterious PC damage

[fangot]

Which of the following is likely to cause the damage:

1) a live ethernet cable with a heavy duty staple through it

2) soldering a vga cooler fan cable which the PC is powered on and running

The damage to the motherboard is a no longer functioning onboard ethernet port and 6 onboard multi-coloured sound jack ports.

I don't know why you'd do either. But the second is probably the one that killed it.

That said, having a faulty ethernet port means the first is a bit odd...

well the staple was accidental, whilst the cable was being routed a day or two before

the soldering was obviously a mistake, but i didnt think heat alone would short something out

with mad skills like that there should definitely be a career with the purple shirted ones on the cards.

The heat from the soldering iron isnt the concern IMO.

The earthing/shorting of a live circuit through the iron seems a bit more plausible.

 

[fangot]

ok so by momentarily seperating the soldered connection with the hot iron, that shorted something out?

 

[CaNsA]

Chucking a bit of metal into a live circuit is never a good idea.

 

[fangot]

okay, doesnt matter whether its 12v or a higher voltage, its going to short it?

 

[CaNsA]

Motherboard components are very sensitive to voltage change, as we all know.

Juice is trying to go from A to B.
You chuck a soldering iron tip in the middle of that and the juice is getting channelled through the iron to -V (or its equivalent)

B is expecting some juice to do what ever it needs it for and cant.

I'm sure someone else will be along soon to either back me up or shoot me down in flames.

 

[fangot]

ok, so i maybe i got lucky too

just a bit random how the onboard sound and ethernet ports were killed. maybe could have been a lot worse damage, cpu, ram, gpu etc...

Why on earth would you be soldering onto a live system??

That's just asking for trouble.

 

[Dunks]

Why would you solder a fan on a running system? My mind boggles.

both on the southbridge, quite probable that one of your actions has killed something shared by both.....and likely other things that you have yet to notice.

 

[Jono8]

Soldering whilst the system is on!!? You mad bro.

 

[dfarrall]

Theres no mystery here, OP is speshul.

 

[Scougar]

lol. Sorry for your loss... I would go with soldering iron... but...

When you say 'live' ethernet cable.. do you mean the type that also carry power?

Also... are you sure these incidents are connected, and it's not coincidence (i.e. a software issue?)

2) soldering a vga cooler fan cable which the PC is powered on and running

[Haggisman]

I would be extremely surprised if shorting an ethernet cable actually killed anything (unless you were stapling it a mains wire? )

lol such a badass
