PC dead but MOBO light on ???????

[w_tom]

Fer crissakes, pop for a new one and put it in. What'll it cost... $30?

Power supply outputting 5.7 volts on purple wire (when voltage should
never exceed 5.25) means power to power supply controller is defective.
At 5.7 volts, power supply controller cannot be expected to operate
properly.

Green wire voltage constantly less than 0.8 volts means computer
should have been on constantly - never turns off. More curiously
interesting facts. Hopefully that too is a failure inside power
supply.

If purple wire voltage had exceeded 6 volts, then semiconductors of
power supply controller (or other parts of computer) may have been
damaged. If power supply was $30 (only the naive recommend a $30
supply), then necessary circuits to protect motherboard semiconductors
may be 'forgotten'. If the failed supply sold for something more like
$60, then protection might mean an undamaged motherboard.

If purple wire voltage never got above 5.7 volts, then probably no
motherboard damage. However if it was a $30 power supply, then purple
wire voltage may have been excessive and is now limited only to 5.7
volts by that damage.

So that future intermittent failures do not occur, a new power supply
is installed and voltages confirmed with the meter. If purple wire
voltages are 'in spec', then the original failed supply probably
(hopefully) did not do long term motherboard damage.

Embarrassing is that one would recommend a $30 power supply. A full
retail price excessively low typically because essential functions are
missing. One reason why that purple wire voltage was limited only to
5.7 volts? That power supply contains protective functions so often
missing in $30 junk.

Embarrassing? To whom?

Reguardless of whether the $30 is 'the best' or whether or not it has
'essential functions' (up for debate - it may be the only essential thing is
that it works - depends on who you are and what this is for, right?)
missing - why should one be 'embarrassed' about offering it up as a
solution? Perhaps they may be lacking by not providing more options - but
embarrassment is a personal reaction - not one you can determine or even
decide that one *should* feel.

I still say - almost two weeks into this - that buying an inexpensive power
supply and installing it would have proven the same results faster and then
you would have a working power supply while waiting on the fully specced and
'full of essential and even extra super-cool functions' power supply came in
from your ordering it online...

However - earlier on - the bulging capacitor theory was presented and there
may be more than one issue with this system...

Shenan will always argue after a previous post described how many
'computer experts' don't even know how electricity works. Shenan knows
shotgunning. He reminds me of a repairmain on a Trident nuclear
submarine who just kept plugging replacement computer boards into the
panel to fix a communication problem. He then declared all six
computer boards defective. He also did not have sufficient knowledge
nor sufficient grasp to realize the slot had destroyed all good
computer boards. Shenan's reasonings are so similar.

Meanwhile, if Shenan had technical grasp, then he knows debate about
missing functions in those cheap power supplies does not exist. He
demonstrates neither technical knowledge nor experience. He just knows
only from shotgunning and some credentials posted after his name - as
if that says he knows how electricity works.

Embarrassing is anyone who somehow knows a $30 power supply is
automatically better. Provided in far less time to shotgun - provided
by that meter - is why the system is failing and why concern for
integrity of other system components exists. 5.7 volts is unacceptable
for purple wire voltage. It is possible that problems could have been
seen and eliminated before the system failed. But again, power of a
multimeter and some basic electrical knowledge.

Power supply is defective - obviously. Question remains about other
hardware. Questions that a shotgunner could never ask without
comprehending numbers. Insufficient knowledge is also why selling $30
power supplies without essential functions is so profitable.

With respect Shenan, if I could respectfully point out, considering your
title you have probably been a most unhelpful MS-MVP.

Your 1st post:

See the answer in the other groups...
I think you have spread it a bit thin with the cross/multi-posting.
Next time - put it in one place and wait for some hits. heh

*(unhelpful and Slightly sarcastic shall we say. heh)*

4) If your 2001 motherboard is ready for the dumpster, then why am I
still using early 1990 computer on the internet (not all internet
functions, but even they work just fine)?

Because you are stubborn and are happy with whatever you have or because
you don't have the money to upgrade.
No one said it wouldn't work - there is a time vs. money factor in
anything. I can spend 2 weeks getting a $35 part to work or I can replace
it in 30 minutes, if I have a long drive to get the part.

Each their own... If the OP enjoys testing and fiddling with such things -
fantastic - go on.

*(A little condescending if I may say, also you agree each to their own, so
maybe you should have left the discussion from this point forward)*
------------------------------------------------------------------

4th:

I don't know about you - but I get paid more than $35/hour net.
Not everyone makes that much - that's a given - which would make it even
more logical to spend as little time fiddling with it and more time doing
something productive to make money off of.

*(Well I don't mind admitting I don't earn that, but also I'm not going to
lose a profit because I'm fiddling in my own time and my only profit is
learning)*

This problem has been going on for almost 2 days. That's a lot more than
even the most expensive power supply you could buy for a normal home
computer system (ATX). Cut out all you want, recommend all you want - I
argued nothing electrical with you - just common sense.

*(You don't seem to grasp that this problem as you say has no time limit to
suit your needs, you can simply ignore this thread if it upsets you and you
could
earn your title by helping others, assuming it takes no longer than 48 hours
to fix) * "excuse the pun."
---------------------------------------------------------------------

5th:

As I stated in a previous post:

Each their own... If the OP enjoys testing and fiddling with such things -
fantastic - go on. However - there are other options - faster and possibly
less expensive in the long run. Presenting those options is a valid
point -
just as presenting the testing options is a valid point.

*(with all due respect it is a valid point, but you are mainly
hampering,badgering and dismissing other peoples advice)*
---------------------------------------------------------------------

6th and hopefully final:

I still say - almost two weeks into this - that buying an inexpensive power
supply and installing it would have proven the same results faster and then
you would have a working power supply while waiting on the fully specced
and 'full of essential and even extra super-cool functions' power supply
came in from your ordering it online...

*(Still arguing with Tom)*

However - earlier on - the bulging capacitor theory was presented and there
may be more than one issue with this system...

*("And there shines a light" ...Although the meter test didn't conclusively
solved the problem, it most certainly told me
the PSU was defective, and Tom taught me something in the process and I
enjoyed the experience.)*

And yes I will install a new PSU and hopefully the MOBO will be unaffected,
if so great, if not then so be it.
Sorry for pointing out your posts, but you may see how I've looked upon
them.

With respect...

You asked on a public newsgroup.
I gave my solution.
My arguments with w_tom have nothing to do with you/your request - and are
my opinion.

I dismissed nothing... I pointed out options.
Options should be given.
This thread - despite what you believe - is not just for you - but for the
millions who might search and read it later.
Therefore - they may not have the same interests as you and may want to do
the $30 replacement, it works, then they go out and get a real nice power
supply. But if they are not presented that option - they may not know they
have it. What's wrong with me presenting the OPTION?

This thread did not upset me in any way.
I merely continued to present my opinions and the alternative...
I meant nothing in a condescending manner.
I just like presenting all sides of a story.

I am glad you enjoyed your experience.
I am glad you learned something.
Good luck with your replacement.

Ah! well, the horse has bolted now. I did feel your comments were
condescending, but if you feel they weren't then I apologise.

Hi

Just to let you all know. I got a decent 300w PSU and everything is up and
running, and the MOBO wasn't damaged luckily.
