Computer freezes while watching video

All my video games play without a problem, even older ones.
No, I haven't tried that yet, but i might give it a try

Beeing in the business for some time now, i've seen this problem (not exactly similar..) in various ways. Even i had a similar problem wich started by not having ffdshow installed.

I also see u use an external player. im not familiar with kmplayer so ill try to give an common option you can try.

You say the problem keeps coming back every time you reinstall windows. and at the same time you install your "codec pack". I would try to play the movie using just windows media player and a codec pack downloadable from: "http://www.cccp-project.net/" (this pack is the same i use for all client pc's i encounter and works like a charm for about 1.5 years now)

is it the same movie that hangs or do all movies freeze up?

what type of video are you playing? wmv, avi (divx), VOB (dvd) this might narrow it down...

Hope this helps

Does the file play OK on another machine?

The subtitles are a distraction.  If they are being pulled from a separate file they will display fine even if the decoding of the video isn't working (they are displayed in a separate layer over the video playback) so unless they are part of the video image don't use them as a guide.

This happens with all media players I use (WMP, Media Player Classic, The KMPlayer, Winamp,...).
It happens at random, If the problem occurs while I'm watching a file an I restart my computer, it won't happen at the same place as it did before.
It has happened on at least 2 different video codecs, AVC and Xvid.
Yes, the file is OK, it works perfectlyon other machines.

Does the problem occur with all your files?  Wonder if it's a resource issue and you have other processes running in the background which bring down the playback.

No, it occurs in random files at random times. Sometimes it occurs more than 5 times in an hours, and sometimes it doesn't occur for days.

OK this is going to sound a little weird but can you reboot into Safe Mode (the one without networking) and launch your video clip as normal?

I'm afraid you won't get sound but if you can watch it though to see if you get the same effect...

THe idea behind this is we already know the file is OK because it plays on another machine.  It happens randomly though the file and this is most likely to be because something else is taking your system's resources.  Safe Mode will remove most of the background resources and disconnecting from the Net will prevent any updates running.

Let's see what happens ...

I'm sorry if i explained badly, but what I meant was, that sometimes, the error won't occur even if I play the whole file multiple times over. It pops up for no reason with no apparent preference to player, file, codec, time,...
So unfortunately, I can't test it because it happens randomly and sometimes days apart.

OK no problem - this is one of the joys of not solving problems face-to-face :)

Working on the basis that it is to do with background processes have you done an up-to-date scan for malware?

(Recommend Malwarebytes if you don't already use it)  Also, with the exception of your antivirus - try switchnig off background updates for everything for a few days.

Hehe, I kow what you mean :).

Yes, I regularly scan my computer, but not with Malvarebytes, since it's only for 32 Bit Windows (mine are 64 Bit). I use Spybot - S&D, and I think it does the job fine.

OK, I will try that and see what happens.

My graphics card is MSI N9600GT-T2D512-OC V127 (Red one)
I doubt I have any heat problems, because my case is always very cool (6 14cm fans)
It's definitly not a socket connection problem, because I dissassemble the case and clean every component during every reformat and I always check if the HW is properly connected.

It is possible that it a loose chip is causing it, but I don't know of any other way t ocheck for that other than to manually check every chip in my PC :s

Yes, it also appears when I play the video on a connected TV.

If drivers are right and display is bad on TV and Monitor then most likely a PCB level problem

Did you check the soldering on the PCB?
MSI's QC - not so good for a long time.

Have you reseated the actual video card?

You need to check your video RAM.
I know utilities exist to do that but I haven't had to do it in so long I don't remember what they are.
[Other Experts assist please]

.

Do you have windows search 4 installed? Check your add remove programs. If so try disabling it in services unless you really need it. (its a bugger cpu hd hog at times).

It sound like you have something running in the background that is causing the problem. Something is stealing CPU time and effecting the video playback.
Try disabling any items you don't need in your boot start up too.

Something stealing CPU time will usually make video slow or hang.

Patterns like shown in photo are usually caused by an corrupt signal.
Usual cause of that is bad RAM or some other circuit board level problem.

Do any of you know any good CPU and RAM testing utilities?

memtest or memtest86 for RAM.
None better that I know of and it's free.

I've never seen a CPU test that tests all functions of the various common CPUs.
I'm not even sure that's possible through software without a program the size of Windows.
-
There are a number that are good at what they do but they don't do everything.
I don't bother with them so I'll let the other experts chime in on the attributes of those.
.

Time for an update:
I disabled all updates for over 2 days and the problem still occurs.
It's not RAM, because I switched my sticks with my brothers' and problem still occured.
I'm still testing other possible solutions and will update if/when a solution works.

If anyone has any more ideas, I would love hearing them.

Oh, just in case something might be overheating, does anyone of you know the max temperatures for ASUS P5N-D motherboard and MSI N9600GT-T2D512-OC graphics card?
I found the max temps for all my other HW and they're well under the limit

Well, it looks like it was caused by the motherboard, because it died on March 11th and I got a new one back and the problem hasn't been seen anymore
