When I play a 1080P video on my plasma my computer shuts down after
approximately 2 minutes. When in the bios health page I see that shutdown
is selected for CPU at 70C and that when in the bios page the temperatures
are:
CPU 60C , case 35C
Of course when my video is playing I cannot see these temperatures.
ECS K1N SLI Extreme
AMD64 +4000
Nvidia 8800GT dual DVI
Media Player Classic
Pioneer PDP-LX508d plasma
files are TS
When I play the same file but output to lower resolution to my LCD computer
monitor there is no shutdown.
One point of which I am uncertain is whether a video card if overtemperature
can shut a computer down?
I have all fans running at max and I do not overclock.

OK, I have a program that doesn't use the video card. Prime95 will load
up the CPU and run it at 100%. (Select "Torture Test" when prompted.)
This will give you an opportunity to see how hot the CPU gets.
This program is used to measure temperature and control fans. Start this
running before Prime95, and see what your idle temperatures are like.
Then, run Prime95, and wait a couple minutes for the CPU to heat up.
That will give some idea how hot it would get while playing movies.
It should be able to read out the three temperature channels on your
SuperI/O chip. As well as a few other things, like maybe the hard drive
temperature (as reported by S.M.A.R.T).
The CPU has a signal called THERMTRIP, and that can be used to turn off
the computer. The power supply may have overcurrent or overtemperature,
and the power supply could also shut off if it detected an extreme
condition. The video card, AFAIK, doesn't have a way to turn off the
computer in its hardware. The driver might have the ability to monitor
temperature (maybe a program like GPUZ or Rivatuner could access that
temperature readout). You'll have to look around, and see what utilities
can read out the GPU temp. It is even possible that Speedfan can do that
now.
The three temperatures you want to measure, under as extreme conditions
as possible, are room temperature, computer case air temperature, and
the CPU temperature, all when the CPU is at 100% loading. Prime95 is
one way to get that kind of loading.
Once you're finished with Prime95, you can stop and exit from it, and
move on to the next test.
You'd want to measure GPU temperature, under some extreme condition for
the video card. I believe ATITool has a stability test, and you could use
that to load up a video card. You should be able to still see the other
utilities on the screen, while ATITool is running.

Paul,
Thanks again for the help (you helped me in a different thread re memory
testing and all checkd out okay but I'm still getting shutdowns)

1) 70C is too low, set that higher, to at least 75-80C.
2) 60C idle is too high, you need either reseat the
heatsink, clean out dust, use a better heatsink, or increase
case cooling. I don't mean 60C by itself is too high but we
can assume it goes higher under load, 60C is indicating not
enough margin for loaded operation. If under load it never
went over 60-65C that would be more tolerable and yet even
lower can be possible with an amount of effort or cost
dependent on where the problem lies. If this is a HTPC case
it might be more likely to have poor airflow.
>Of course when my video is playing I cannot see these temperatures.
Not really necessary, we can reasonably infer that a 60C
idle temp goes up significantly playing HD video. Note that
although your video card has HD decoding acceleration, Media
Player Classic does not make use of it.
To make use of it you need a player that supports it like
PowerDVD, or I think "Media Player Classic Cinema" (Google
for it) recently has DXVA support for acceleration, though
you may also need an nVidia.com driver that's in the (I
forget exact version) 150.00-something or maybe
160.00-something series or newer. Best to just get newest
driver and try it. IIRC Media Player Classic Cinema or the
other players also have settings to configure to get the
video card acceleration to work, it would be obvious when it
does by a sharp dropoff in CPU utilization.
The video acceleration is no good substitute for improving
CPU and/or case cooling to resolve that factor, the system
should be able to run at full load regardless of whether
video playback acceleration is ok.

Probably because that's less load on CPU, by changing around
some Media Player Classic settings you may also be able to
reduce processing. I don't recall all the playback output
settings in it's menu but some will cause more of a load
than others.

Through software/driver monitoring I suspect it can, but it
should also first generate a warning that you would see in
Event Viewer. It is not likely that your present issue is
video card overheating unless the video card fan wasn't
running, currently outputting the video with Media Player
Classis is only a trivially low load on the video card.
>
>I have all fans running at max and I do not overclock.
CPU is first, find out why it's at 60C idle. Aim for closer
to 50-55C, lower being even better but 50C is probably good
enough to not put a lot more time or expense into it.
Is this system used for both PC/traditional computing AND
home theater viewing? It just seems a bit mismatched...
that the 8800GT is overkill for playing back movies on a TV,
but the A64 4000+ is going to bottleneck many games.
Regardless, if you find the gaming performance acceptible,
if required, one way or another it should be possible to get
the combo to both run at lower temp and make use of the
video card HD acceleration to offload some of that from CPU
for at least *some* video playback... I don't recall all the
little issues involved in which formats nVidia's drivers
and/or 3rd party application built-in code currently
supports, the last time I checked that was still a work in
progress getting HD acceleration/PureVideo2 HD to work on
newest generations of video cards, even though 8800GT is
arguably not a new generation anymore, it's not very old
either.

that CPU temp is way too high and my AMD X2 3800 shutdowns at 70c regardless
of whether any shutdown temp is setup in the bios or not so I *think* you'll
be getting the same
reaction. It could be the CPU heat-sink isn't fitted correctly.
Another possiblity is the graphics card is running very hot and in tower
case that means its below
the CPU and the heat rises and warms up the CPU heat-sink.
So install Rivatuner and check your graphics card temps and also refit the
CPU heat-sink with fresh thermal paste.
Re: How to monitor temperatures to avoid shutdown?
Hi!
I used to have the same trouble on my older desktop, and I finally found that
a drop of oil in the CPU fan bearing solved the problem: The cpu temp
reported by speedfan used to reach 75-80 while running even Excel, and the
CPU speed would drop drastically; and I noticed the fan not rotating with the
'invisible blade' speed. I was not sure, but the fan confirmed it for me by
coming to a stop. I exposed the bearing of the fan(there was a metal film
sticker over it), and dropped a drop of 30g machine oil. The CPU temp jumped
to 34degC (room temp 30)

Re: How to monitor temperatures to avoid shutdown?
Thanks to all. Due to other personal issues I have still to resolve the
shutdown issue.
