ATT: w_tom. PC dead but MOBO light on???????

Take the power supply by itself or take case only to a reputable pc shop,
they'll check youre system while you wait,usually free of charge...

Light says power cord connects to AC mains. Light does not say any
voltage is sufficient. Only meter numbers can say that. Start by
measuring voltage on purple wire by pressing meter probes into 20 pin
nylon connector for purple wire and to any black wire (or touch
chassis). With computer powered off (and light still illuminated), that
number must exceed 4.87 (and it probably will).

****5.7**** PURPLE

Next take the number
for green wire both before and when power switch is pressed. That
number should be above 2.0 volts and drop to less than 0.8 volts when
switch is pressed. What happens here is very informative.

****0.02...both switched and unswitched **** GREEN

Next, the gray wire. It must rise to well above 2.4 volts within
second of the power switch pressed. I suspect either voltage will not
move or will rise and then fall.

****0.01**** GREY

Now measure any red, orange and yellow wires when switch is pressed.
Assuming the green wire voltage did drop, then each voltage here
should rise up (and then will probably fall). Any voltage that does
not rise up, then look for a short circuit for that voltage on
motherboard. If all voltages do rise up, then within a second, each
voltage must achieve more than 3.23, 4.87, or 11.7.

Hi

I've been getting the BSOD for the last couple of months and I thought It
may have been my DVD/RW drive, (sorry no info because of first sentence)
but
a couple of days ago I was converting an .avi to .vob, (DVDsanta)...and
when
I went to check on it my PC was dead.

The fuse in the kettle lead was ok so I opened up the tower and seen that
the light on the MOBO was on, so I took out my HDD's and disconnected
everything except the 20 pin supply to the MOBO and tower and CPU fans,
but
to my dismay when I pushed the power button on my PC the fans didn't kick
in
(1...does there have to be a HDD with the OS installed for the fans to
work?) So I'm under the impression that either the power supply is
knackered
(2...but why is the MOBO light on?) or The MOBO is knackered, but then
again
I'm no expert and was hoping some tech buff could help in solving my
problem
(3...could the power supply have failed but have enough power for the MOBO
light and nothing else??)

I know the simple answer is to take it to a PC repair shop but I'd rather
save money "as we all do" if someone may help me solve this.

MOBO: ASUS A7A266
Power supply: FSP group inc
Model #: FSP250-60GTV (PF)
WinXP Home SP1

"Thanks for the info Andrew"

I must state that I am interested in the fault findind aspect of the problem
and was waiting for a response from "w_tom", as this subject has been quite
extensively discussed already further down in the posts as you may well see,
I look upon it as a project as I am already looking to buy a new machine for
my needs.
I'm just trying to learn a little as I go and if I can't do it myself, then
I'll have it repaired proffesionaly to retire it for the kids to use, thanks
for your comments though, I'm sure it benefits others too.

Hi Curt

Thanks for the info, my local library is only 100 yards from my front door.
:-)

As you say it's a mind blowing subject on the issue of buying a PSU to suit
the needs of a particularly specified machine you want it to support.
Below are just a few examples of what info I've been studying lately.
Some say a 300 - 350watt PSU is sufficient for the most demanding of
machines in today's market, although a PSU calculator will tell you exactly
what wattage PSU you require from the components and peripherals
installed...etc for your particular machine, which tends to be a lot higher
than 350watt in my case for a new machine, but doesn't explain that it's
calculated sum is what the machine would require if all it's organs (shall
we say) were running at full load at the same time, but in reality for the
majority, that wouldn't be the case.

It's quite stimulating reading, and after all's said and done you have to
make an informed decision from the pro's and con's of it all.

p. mc,

Thanks--those are some good sites.

Check out Scott's book(s)--they are really good. I've been using them as a
reference for several years now.

For a new machine in todays world (P4's, kick*ss video, several HD's etc),
400 watt or even more is certainly not out of the question. Good luck, and
post back if need be.

Hi Curt

Yeah I'll definitely check that out.
BTW this is the specs for the new machine I'll probably purchase. It's
geared more for the gaming enthusiast, as I'm sure the kids will like ( "me
too", but I'm sure it's overkill for TW PGA Tour) but also it's future
proofed and there's lots of processing power and memory for video editing
and particularly audio orientated stuff, 'cause I do production cd's for a
theatre company (SFX). I'm just doing the sound tech for a musical called
"Like I've never been gone" at present for a community theatre group, it's
about Billy fury's early days and showing in the Gladstone theatre (Wirral)
with the original Fourmost performing throughout the show if anyone's
interested take a look at the link.

p. mc,

Thanks--those are some good sites.

Check out Scott's book(s)--they are really good. I've been using them as
a reference for several years now.

For a new machine in todays world (P4's, kick*ss video, several HD's etc),
400 watt or even more is certainly not out of the question. Good luck,
and post back if need be.

Hi Curt

Thanks for the info, my local library is only 100 yards from my front
door. :-)

As you say it's a mind blowing subject on the issue of buying a PSU to
suit the needs of a particularly specified machine you want it to
support.
Below are just a few examples of what info I've been studying lately.
Some say a 300 - 350watt PSU is sufficient for the most demanding of
machines in today's market, although a PSU calculator will tell you
exactly what wattage PSU you require from the components and peripherals
installed...etc for your particular machine, which tends to be a lot
higher than 350watt in my case for a new machine, but doesn't explain
that it's calculated sum is what the machine would require if all it's
organs (shall we say) were running at full load at the same time, but in
reality for the majority, that wouldn't be the case.

It's quite stimulating reading, and after all's said and done you have to
make an informed decision from the pro's and con's of it all.

Excellent forums

Hi p. mc,

Although I'm late jumping in on this thread, I have been keeping track
of
it.

This would be difficult to t-shoot over the telephone in real time, let
alone in a newsgroup.
For some excellent hardware info. (including power supplies) go to your
local library, and check out a copy of Scott Mueller's book Upgrading &
Repairing PC's. I think he's just releasing the 17th edition--so it's
been
around a while. Beware, it may be *more* than you want to know (1000+
pages).

| "Thanks for the info Andrew"
|
| I must state that I am interested in the fault finding aspect of the
problem
| and was waiting for a response from "w_tom", as this subject has been
quite

well
see,
| I look upon it as a project as I am already looking to buy a new
machine
for
| my needs.
| I'm just trying to learn a little as I go and if I can't do it myself,
then
| I'll have it repaired professionally to retire it for the kids to use,
thanks
| for your comments though, I'm sure it benefits others too.

| Light says power cord connects to AC mains. Light does not say
any

by

pin
| nylon connector for purple wire and to any black wire (or touch

illuminated),
that

|

| (all connections and peripherals connected and light still
illuminated)
|
| ****5.7**** PURPLE
|
| Next take the number
| for green wire both before and when power switch is pressed.
That
| number should be above 2.0 volts and drop to less than 0.8 volts
when
| switch is pressed. What happens here is very informative.
|
| ****0.02...both switched and unswitched **** GREEN
|
| Next, the gray wire. It must rise to well above 2.4 volts
within
| second of the power switch pressed. I suspect either voltage
will
not
| move or will rise and then fall.
|
| ****0.01**** GREY
|
| Now measure any red, orange and yellow wires when switch is
pressed.
| Assuming the green wire voltage did drop, then each voltage here
| should rise up (and then will probably fall). Any voltage that
does
| not rise up, then look for a short circuit for that voltage on
| motherboard. If all voltages do rise up, then within a second,
each
| voltage must achieve more than 3.23, 4.87, or 11.7.
|
| ****0.47*** RED (un/switched - swithched)
| ****0.30**** ORANGE (un/switched - swithched)
| ****1.19**** YELLOW (un/switched - swithched)
|
| Information from those quick measurements either make it obvious
| which is the suspect or post those numbers here for better
analysis.

| Hi

| I've been getting the BSOD for the last couple of months and I
thought

| but
| a couple of days ago I was converting an .avi to .vob,
(DVDsanta)...and
| when
| I went to check on it my PC was dead.
|
| The fuse in the kettle lead was ok so I opened up the tower and
seen
| that
| the light on the MOBO was on, so I took out my HDD's and
disconnected
| everything except the 20 pin supply to the MOBO and tower and CPU
fans,
| but
| to my dismay when I pushed the power button on my PC the fans
didn't
| kick
| in
| (1...does there have to be a HDD with the OS installed for the
fans
to
| work?) So I'm under the impression that either the power supply
is
| knackered
| (2...but why is the MOBO light on?) or The MOBO is knackered, but
