I built a AMD 2200+ on the A7N8x non dlx in Sept of 2003.
It has been working fine until today, I ran Prime 95 and left the room to do other things.
When I came back, maybe half an hour later I turned on the monitor to
see the results. The Monitor remained dark I placed my hand behind the
power supply fan to feel for heat since today was warm. It seemed warm
but could not feel any air movement I looked at the fan and it was not
working then I tried a warm reboot ctrl+alt+delete nothing was working
so I pulled the plug to let it cool. Now that it's cooled nothing
happens i believe the power supply is dead, if that is the case would
it damage anything else? I figured I would ask the group before
tearing it apart, since I don't want to cause more damage than I
already have.
Should I replace the power supply and see what happens?
Thanks.
 
It sounds like the powersupply got hot. DOes the power supply have an on off
switch? Try switching it off then on. Then turn on the computer. If this
works, then the PSU (Power Supply) fan(s) probably siezed. IF that is the
case, then replace the PSU and you're good to go.

Also. IT's not a good idea to turn off and on the monitor while the computer
is running. It reduces the life of the monitor and possibly the computer
itself. THat's what screensavers and those power settings within windows are
for.

Hope this helps
 
For pete's sake, where does all the disinformation come from? You can
turn your monitor off any time you like and it will NOT harm the
computer nor the monitor. A monitor is designed to endure some
reasonable quantity of power cycling.

If the fans in the PS are stuck or not moving freely, you might
carefully peel off the bearing seal (it's on one side of the fan,
looks like a small sticky circle) and lube the bearing with a couple
drops of some decent quality lube (I use the Teflon based stuff, a
light lube oil) and this brings most fans back to life. Carefully
replace the sticky bearing seal over the fan bearing opening.
However, if after cooling off your rig, the PS did not come to life on
depressing the power switch, I'd suspect it went south and the PS
would be the first item I'd swap out.

I do agree. It's the same when monitor go in power save option. It is
turned on and off exactly like when u turn it on and off via power button,
especially new generation and LCD screens :-(((

I call it disinformation :-((

BTW, on the subject: too many people run cpu torture software also when it
is not needed.

I usually set my computer up, then I use it for everyday task: if it never
fail, I don't feel the need to run critical software. I just use software
like Prime95 if everything not work as expected.

The purpose of running tests like memtest86, Prime95, and 3DMark2001se,
is to detect broken hardware before the 15 day return period is up
with your vendor. It is easier to return an item to your vendor, than
to arrange a warranty return with the manufacturer.

You should run memtest86, so memory errors don't cause something
critical, like your registry, to get damaged. Any info read from
disk into memory, then later written back out, could get corrupted
by the use of bad memory. That is a good reason to run a memory test
program, before you even install an OS (memtest86 self boots from
a floppy disk).

Prime95 causes the processor to heat up. It tells you whether your
CPU and case cooling are adequate. If Prime95 gets roundoff errors,
that could indicate that a portion of your CPU is bad, and cannot
be trusted to calculate your income tax return :-) It could also
indicate something is wrong with the Vcore regulator on the motherboard,
with the Northbridge, or with the size of your PSU, on rails like +12V.

I use 3DMark2001SE and Dxdiag, from DirectX, to determine whether
my AGP video card is set up in the most efficient manner possible.
For example, on my last build, I found AGP textures were disabled,
by looking in the Dxdiag screen. Running 3DMark, I could see a
difference in the score going from 14000 to 17000, when AGP textures
were re-enabled. Using programs like this, helps you tweak and get
the performance you paid for.

I always recommend running test programs when the hardware is new.
You can use the programs to collect baseline information - like
the memory bandwidth readout in memtest86, the score in 3DMark and
the temperature rise of the CPU, above the measured case temp and
the room temperature at the time. You can refer to these values
in the future. For example, say you run Prime95, and the CPU gets
up to 55C. If you run the test a year from now, with same room temp
and case internal temp, and the CPU is at 60C+, that might be a good
indication of the need to renew the thermal compound on the CPU.
You won't know when to do it, unless you know the history of your
hardware.

HTH,
Paul
 
No one that I have ever known bothers to renew the thermal compound on their
HS at all.
I never do and have never had any problems.
My first pc, second, third and now this one has the same compound on it as
when first built.
Too many people go on about their CPU and case temps being this low, that
low..............
put them all in the same room in the same part of the world at the same time
of year and then see how low their temps are not!!
Dream on.....................
Temps go(and will)up and down with changes in room temp...............
turn the heat up and I suppose the case and cpu temp goes down does it???
NO WAY

Got to disagree with your disagreement!

Electronically switching the monitor into standby is far less
problematic than using the mechanical power switch.
Firstly, power switches arc and are one of the first things to fail.
Secondly, the degaussing power surge is pretty large, its just not good
for anything (a UPS takes a bit of a battering !).
The monitor switch works, but its just better not to use it if you can.

Its like saying a car is designed to be turned on and off.
Yes, but its the time when maximum engine wear also takes place!

This is a temporary solution. The PSU will just die again later because the
fan motor had been stressed in the first place. You'd have to lube it up
more and more often. Worth a try though.

Which might mean something if you never actually remove
the power from the monitor, for most users leaving the monitor
in standby or on 24/7 would bring the monitor closer to failure
ratings than cycling the power a few times a day. Now if you
have a sugared-up hyperactive 7yr old playing with the power
switch, all bets are off.

In a way, I agree as I have mine on a switched power strip and
the monitor has its power cutoff right along with everything else.

The only thing I care about, is that people are aware that their
computer needs cooling. Some people who visit this group, think
their PSU fan is enough to cool a computer, and unless they are
using a mobile processor and a low end video card, that is
unlikely to be enough.

Since very few posters give room temp, case temp, and CPU temp,
it is hard to explain to them about delta_T being the important
thing, and not the absolute temp on a given day. The delta
from room to case, tells you whether the case has enough fans.
The delta from case to CPU, tells you whether the CPU HSF is
good enough for the processor. Running the processor at 100%
while doing a test, raises the delta between case and CPU as
much as it is ever going to be raise (that is delta and not
the absolute temp). Once the deltas are known, all you need
to know is the room temperature, to predict what temp the
CPU will reach. If on one day, the three temps are 25,35,55
and on a second day, the room temp rises from 25 to 30, then
you know the result will be 30,40,60. You can even figure out
how hot the room can get, before it is unsafe to run the
computer, or how hot the room can get before you can expect the
computer to crash.

So, that is the whole purpose of cooling your CPU. It gives
you the headroom, to run the computer on a hot summer day.
If you ignore the cooling, then your computer room had
better be air conditioned :-)

And finally, I don't really care that much about the CPU, as
on paper, the disk drive is much more fragile and likely
to have its life shortened by the environment it is in. Since
many of the people visiting here have no backups, that is a
much more important component to protect than the CPU. At
least having good case cooling will help with that a bit.

To see a temp/humidity curve for a disk drive:

Care to explain your statement here, or is this just an unsupported
guess on your part? I stand by my original assertion, turning your
monitor off will not harm the computer nor monitor. If you have
access to some unknown knowledge here, please share it, or refrain
from offering misleading information.

All solutions are temporary, it all depends on your unit measure of
time.

LMAO, you can stress one of those motors all you want, they are
brushless DC motors. Now, the bearing may have endured sufficient
wear that it will not recover, I've seen this to be true in some
cases. However, I've also seen bearings last 1 or 2 years after a
lube job. It all depends on the specific failure mode of the bearing.

I'd be interested to see the evidence to see you back this up.
I for one tend to never switch my monitors off, even if the PC itself
is. And I don't get any problems with my monitors.

Click to expand...

I certainly have in the past. As an electronics engineer, I'm fully
aware of the differences between manufacturers quoted specs and the
ability of a switch to remain operational to these specs when faced with
having to deal with continual momentary surge currents which are
probably well in excess of its rated continual operation parameters.

If
you work in an explosive atmosphere that arc might be an issue,
I suggest you keep your monitor out of any battery boxes while the
batteries are charging.

I suggest you find out what happens to the contacts in a switch when
subjected to repeated arcing.

It might be good for Oh.... degaussing?? An UPS should be able
to take it, it's designed to handle more than that, or why have one.
Click to expand...

Oh really? Get an average UPS, run it with a load pretty close to its
max (as many people do) and then switch a big monitor on and off and see
what happens.
If you have a room of computers and all the monitors are in the 'on'
position, but the master fusebox is off - you throw the switch to the
room. The circuit rating is supposed to be able to cope, but what
happens? The trip usually goes straight away?? Why is that then?? It
doesn't happen when the monitors are switched on one at a time.... I
wonder why that could be??????
Yes, all those moving parts in my monitor. Wait the only moving
parts ARE switches, maybe you DO have a point.

In my room to my left is a 28" telly (that's like a big monitor in case
you weren't sure) waiting for me to fix it. It works perfectly apart
from one thing...... the power switch has gone. Why? Because the people
who own it don't like using standby and use the switch all the time. Now
its f****d.
And I'm sure its designed to be able to run the telly.
And I'm sure it has a spiffing MTBF

LOL indeed.

http://www.energy.unsw.edu.au/unswitch/experts.html
Click to expand...

An interesting page in many ways.
Bear in mind that its dealing with the question from an energy saving
issue point of view, not specifically from a reliability one.
Also, the question asked to the manufacturers was basically 'is turning
your computers on an off going to damage it?'
So what are they going to say ...' Oh I'm afraid yes... our machines
aren't designed to a high enough standard to withstand that ...'
(Which of course they could be designed to do - but people wouldn't pay
the extra)

And note there were quite a few who said along the lines of, and I
quote:
'In any appliance, constant switching on and off will result in possible
mechanical or electronic failure. Computers prefer to be left on all the
time'
So its not a unanimous opinion.

FWIW, I actually DO turn the monitor off as you suggest if I'm away for
an 'appreciable length of time', its just that my definition of this is
days/weeks.
Certainly not overnight.
I used to leave all the computers at home on 24/7 as well, but, as was
pointed out in your URL, hard disk bearing wear is a problem, as is all
these god damn fans I now have (I mean, there's NINE in this bloody
machine I'm using now!). And of course the power consumption has
increased over the years.
So I tend to turn all non server machines off overnight now.

Its a compromise.
Still doesn't change the fact that I'm doing no good to my machines
every time I switch them on!

Well it's like someone driving a car and saying you should not use the
brakes..................
because each time you do it harms them............
or the ones who will not turn the monitor on or off by it's
switch...................
and even those who leave their pc on 24/7 because it damages the pc and
monitor if you turn it off.
 
Thanks everyone for your input, luckily the power supply was still
under warranty so I got a new or rebuilt, nothing else was damaged,
working as well as before.
For the power on or off I never found it to be an issue.
I have a P 166mmx O.C. to210, I've always turn on and off with no damage,
they seem to become obsolete before they break.
Thanks again Wilf

It definitely doesn't do the PC any good to keep power and temperature
cycling the thing. Monitors really don't mind so much. In olden days
socketed chips would creep out of their sockets under temperature
cycling. Even today, if something in the PC is going to die, 9 times out
of ten it'll die during power up, when the stress is maximum.

Its exactly like that.
Do you think that braking has no effect on the brake pads and disks?

Would you not agree that someone who uses excessive braking and
acceleration over smooth driving will have to spend more money on more
frequent servicing because the hardware will fail at a more frequent
rate??

You have to brake. Just don't when you don't have to!
