So tell us, which binary newsgroup should Lara (OP) use to post an image
relevant to this thread post? And don't you think the users of that group
are going to get fed up with us hardware guys posting off-topic images from
time to time?!?

CBFalconer is correct, this is not a binary group.

There are many options for hosting an image that can be
linked to in the usenet message. Among them:

ISP provided webspace

Your own webserver, whether it be via domain name or simply
a static or pseudo-static IP # with some server software
installed on your system.

Image hosts like
http://www.google.com/search?q=free+image+hosting


Sure there are binary newsgroups - they deal primarily in binary posts and
uploads, but are not limited purely to binary - there is some text and
conversations that take place.

This is a text-based newsgroup - it deals primarily in textual posts, but I
don't see why it has to be limited to purely text. Can you please explain to
everyone why an image of a power connector in a thread concerning a power
connector could possible be considered garbage, of interest to very few?

It has to be limited because of two main factors:

1) Many ISPs automatically strip off attachments in
non-binary groups, or in all groups per their policy.

2) Where would it end? If you allow one person to post an
attachment, then you can't so easily deny another person
from posting two or three or four, and they may be multi-MB
BMPs or who-knows-what.

There is a deliberate segregation in that ONLY binary groups
are supposed to have attachments. Please don't try to
rewrite usenet rules, they exist for good reason.

thank you to all of you,,

Sorry if i'm late , the reason is my work..

Today , I tried again to change power supply then only the power
supply fan and processor fan are power on for a second then suddenly
these fans are stop and I faced the same problem again nothing
happened when I press the power button,,

One reason, would be CPU overheat. Check that the heatsink is
secured to the processor, and that the CPU fan is plugged in.
Remove dust from the heatsink fins, if heavily encrusted.

And who cares - just don't download the attachment unless you know who
posted it and why it might be there. You aren't forced to download and see
all the attachments, only the ones you choose to 'save attachment' or 'open
attachment' on.

The only usenet 'rules' page I have ever read was a discussion on
top-posting verses bottom-posting. I have put the word 'rules' in quotes as
it wasn't a rules page, but just someone's opinion. That particular argument
made a lot of sense and I support that, but I have never seen or read any
official usenet rules. I didn't even know newsgroups were called usenet by
some - I just use Outlook Express and choose which (3) newsgroups I want to
read and contribute to.

This opinion that images and binaries shouldn't be posted seems to stand in
the way of progress and makes things deliverately awkward for people. I
would seriously like to know why you and everyone wants to stand in the way
of progress? Allowing attachments in this group could not cause any problems
for anyone - if you dont' want to see an attachment, then don't open it, so
why blankly forbid it?

Incidentally, who wrote these 'rules' and which book are they published in?

None. If you examine my earlier message, as underlined above, I
made a suggestion which would transmit the binary to all
interested, without annoying the newsgroup.

There is no such 'download' choice. Examine the raw source of a
message with an attachment sometime. You _may_ have visibility
choices.

If you want a forum where attachments are allowed you will
need to go to a web forum instead of usenet, or at least a
binary usenet group.

As with all rules, there's bound to be a small minority that
disagrees... if there were not, there would be no need for
rules, would there?


The only usenet 'rules' page I have ever read was a discussion on
top-posting verses bottom-posting.

Then it seems you have not sought to find any. How about a
basic google search, even a web search at that instead of a
groups search...

Understand that part of usenet's virtue is universal
accessibility, low bandwidth, universal support. Just
because you happen to want attachments, that is not the
purpose to a non-binary group.

Perhaps you have a high bandwidth account, but what about
the rest of the world? What about the burden on news
servers which are already at or beyond capacity? In some
cases with some ISPs, people are lucky to have the ISP still
carrying usenet service at all. A single binary will tend
to be multiple times the size of all the text in a typical
group for one if not many days.

Plus, using OE you should know more than most that
attachments are a security risk. OE has in the past been
vulnerable to things you didn't have to actively open by
choice. Was usenet supposted to wait until _you_ decide all
newsreaders are safe 'n secure? What date was that exactly
or has it not arrived yet?

Lots of things seem like progress, but are fairly minor
details. If you would like to offer free hosting and anon
access to a fileserver then you can offer that whenever
someone wanted to attach a binary. Otherwise there are
other ways to get an image hosted, and considering the time
spent posting, taking a picture, it is very little effort to
just post to another site and link it here.

I will now time how long it takes me to link an image
attachment.

First I'll google for "free image hosting".

First identify all components in the power supply system. Power
supply is only one component. Another is the switch. Two minutes to
get these numbers will either identify your problem immediately OR
provide facts so that others can immediately point at the suspect.
Two minutes will answer the integrity of everything in the power
supply 'system' - which is more than just a power supply. You are
asking for answers that do not begin with "It could be ... " Two
minutes to get these numbers means your next answer identifies the
suspect so that what is actually replaced is actually defective.

Result will be an answer that says such and such is "definitively
good" or "definitively bad". No more maybes. Numbers posted here so
that others who have design knowledge can reply with additional
"definitive" answers - no more speculation.

not only the processor's fan is stoped also the fan of power supply
 
"I have assembled a PC components in the case but.........."
Where did they come from? Like New? 2nd hand etc?
Motherboard likewise? Have you done this before...& did it work/not
work?
Did you follow a m'board drawing/sketch/diagram while building this?
Does anything at ALL move/light up/make a noise/flash or otherwise
look/smell/sound different
than just the second before you hit the t.. switch? No green (or any
colour m'board LED?)
Without answering some questions there are too many variables to
hazard a guess.
starting with..
short on m'board
CPU not sitting right
IDE/power/graphics/video card not seated/socketed correctly.
RAM (as above or incompatible with M'board etc)
What motherboard do you have? Have you or can you get a drawing for
this m'board?
Post as much as you can of the details you can give.

The motherboard is new I ues it for explaining all student touch it
and tried to install it

no LED is light

----------------- ---------------
| Motherboard | +5VSB | |
| |<-------------| |
Push | | | ATX |

------------------ ---------------

1) Switch off the power supply, at the back of the computer. This
ensures the following test gives the proper result.

2) Now, switch on the power supply, at the back of the computer.

3) Use a multimeter to verify that +5VSB is at a 5 volt potential
(You can probe the back of the 24 pin connector to check that.
Connect the ground of the meter, to a screw on an I/O connector,
so that you'll only need one hand to handle the meter probe
while you work.) Connector pinout is here (pg.37), +5VSB is purple in color.

http://www.formfactors.org/developer/specs/ATX12V_PSDG_2_2_public_br2.pdf )

If the +5VSB is not at the correct voltage, figure out why. The ATX
power supply could be bad, or the motherboard could be shorting the
+5VSB to ground.

4) Now measure PS_ON# (green colored wire). It should be at a reading of 5V
as well. That tells the power supply to stay in the OFF condition.

5) Now, press the push button on the front of the computer case.
It will send a momentary switch contact to the motherboard.

6) Measure the voltage on PS_ON# again. It should read closer
to zero volts. A reading of 0.4V would be OK. If it is still 5V,
then the motherboard has a problem, or the push button switch
on the front of the computer, is not working.

HTH,

yes, all the part are new
I use it for explain these parts for students then we installed them
in the case

It would've been helpful to have a concise but complete
description of all major parts, including the PSU make,
model and wattage.

Thank you for your interesting


paul

I'm going to measure the voltage

kony
Darklight

I'm going to give you the information

But, tomorrow i'm in vacation, I hope you wait for the saturday
I'm so sorry for that but all parts are in my work

Thanks again
best regards,,

This small quoted sequence is a serious indication of the poverty

should be unaware of Cervantes and Don Quixote.

Did you also replace the power supply controller? If not, well, as
stated previously, your questions could have been answered by a two
minute procedure. That means even a power supply controller would be
known 'definitively good' or 'definitively bad'. The only useful
answer includes the word 'definitive'.

Old or new part is irrelevant. Relevant is "does each part work
properly in 'your' system". But again, that is what numbers from
that two minute procedure would answer.

Also significant: a 'new power supply' was defined without even a
model number, current outputs from each voltage, etc. As others have
implied, your replies are only as useful as the information you have
provided. Even a perfectly good power supply can be defective inside
another computer. Your symptoms are synonymous with a defective power
supply controller. Symptoms also could explain other defects. To
obtain an answer that is 'definitive', numbers or that two minutes
means the next reply would provide useful answers. Useless are
answers of 'it could be this and could be that'.

Speculation and more questions are your only replies because
information, as provided, is insufficient to create a 'definitive'
reply. "When your computer dies without warning....." starting 6 Feb

I think they stopped because the power supply detected a short and
shut down. I would look for shorts at the motherboard's mounting
holes (top or bottom) or corners (mobos and cases can flex). Add
fiber insulating washers for the former and stick rubber bumper feet
to the case for the latter.

Another possibility are any USB cables that go from header pins on the
mobo to the case's front USB sockets. The 4th and 5th pins on the
cable are probably black, meaning they're for ground, but it's
possible that the 5th pin on the header is for +5V overcurrent
detection instead, so attaching a ground wire to it will create a
short.

Do you have a floppy disk drive in the system? If so, verify that its
power connector is plugged in right because it's easy for it to be off
by one pin and cause a short.
