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. > >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. 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. > >One point of which I am uncertain is whether a video card if overtemperature >can shut a computer down? 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.

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.
From: bnmohan via HWKB.com on 15 Apr 2008 03:05 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) Mohan Sleepy wrote: >> When I play a 1080P video on my plasma my computer shuts down after >> approximately 2 minutes.

Thanks to all. Due to other personal issues I have still to resolve the shutdown issue. regards, Beemer ..
