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

Well this explains it quite nicely it seems.

I suspect the following happened.

Since the PC is not grounded as so many in this world, the 110 volts which
is on the ground wire through the PC entered into the P+7 P+6 lines...
probably going through the entire PC and back into the audio system.

I'd be lucky if everything else still works.

A nice example why ground is dangerous to equipment.

Also why 110 volts must be on case and not dumped back to eletricity grid is
beyond me.

Probably another stupid design.

Bye,
Skybuck.

Blame: PC designers.

There fixed that for ya.

Quite strange how my Sharp TV still works after 20 years, but these latest
usb port/audio crap shit doesnt. Bleh !

At least I dont attach so much stuff to my Sharp TV.

Conclusion: attaching stuff is spark prone.

Bye,
Skybuck.

Ddi you interview millions of users ?

What about all those other millions they died ? ;)

Seriously you should do some interviews among any people you know that have
pcs ?

You do know any people right ?

Ask them if they had a pc death ! ;) :)
You fixed nothing.


It has worked fine for those among us who are actually competent. It
would wok for you for 20 years too, if you could keep your RETARDED,
GRUBBY, FAT fingers off of it!

Nope it would catch fire from the dust collection alone.

Many houses/appartments do not have grounded power wall sockets.

So I suspect the PC death rate to be huge !
You are beyond retarded, boy. able to watch Avatar on that poS 20 year
old TV, are ya? NO? That's what I thought, you ****ing retard.

Why would it not be cable of viewing a shitty hollywood movie ? lol.

You need to wake up to reality.
There, FIXED that for ya.

Some predict the end of the PC.

I can see why ;)

Only if you did not unplug it first.

Alright, you've trapped me again,

It is there because you did not ground it. There's circuitry in your PSU
that essentially forms a high resistance path from line to Ground(=your
case). As your ground pin(and case) are not connected, it will freely
float to some voltage between the two phases.

You have something(_very_ roughly) like the following.
L
|
| |both R very large(leakage from capacitors etc...)
| |
*---*---< you can touch this point,
| | but it hurts. It's the case and
| | the local, unconnected ground pin.
| | --- C_case
| | ---
| |
GND

Do not expect weird behaviour, if you use equipment in different ways
than what it was designed for. It is like pulling slime from your nose
with a power drill.

Even if you tried to 'dump' the 110V back to the grid you could not do
it without ground connection. The wall plug fits both ways, so line and
neutral wire can be swapped at random. You can therefore not connect the
case to the neutral pin that the PSU sees, as that may in fact be the
live one. You'd get electrocuted as soon as you touch it. Even if the
wall plugs were keyed, neutral may not be at ground potential, as it
carries return current and will drift around a bit. The ground bracket
on the plug will _always_ fit to the ground contacts, so that is the
'only' sane reference point for your case. Yes, certain consumer
equipment has just two pin plugs, but that stuff is designed to work
that way.
