OK This is kinda a long story but this problem is driving me mad so here goes.

I had a AMD X2 socket 939 system **** out on me, the motherboard died. So I bought:

Asus P5N32-E SLI (Nvidia 680I chipset)
ASUSTeK Computer Inc.

Intel core2Duo E6750 (2.67Ghz/1333FSB)

4x1GB Crucial BalistiX PC8500 DDR2 memory

Other than that my system is:
GF7900GT
650W PSU
4 HDD's (2x sata, 2x P-ata)
USB DVD burner

Other parts used for testing:
560W PSU
GF 6800 GT

Now this new system keeps crashing when I watch video files like tv series or movies ( divX, Xvid ). Total crash, hard reset needed. sound from video looping. IE: " I have to go to go to go to go to go to go"

I have tried different media programs, media player, media player classics, winamp. And different codec packs. Klite, FFshow ++

I have tried 2 diffrent PSU's, 2 different video card, 2 diffrent sets of memory sticks. The only hardware that has stayed the same is the Cpu and the motherboard during testing. Drivers has been updated and the Windows install was fresh (one week old)

I can watch streaming through sopcast or watch videos on youtube without the computer crashing, but with any file using a media program like mediaplayer and codecs the computer crashes. It has been like this since I put it together a week ago.

Also, Its more unstable with 4 Dimms than with 2. The memory is PC8500 and should do 1066Mhz, but with 4 dimms I can't get it over 833. But with 2 Dimms the computer is stable except during DivX/Xvid playback. Like I said, I have tried diffrenet packs and packs that worked fine on my old computer.

I suspect the motherboard is the problem, but I was wondering if anyone has experienced something like this, It's so wierd it only crashes when I play videos, never during 3D gaming. So it could be software.
I really don't want to send the Motherboard or CPU back, coz then I will be without a computer for about 8-10 days.

CPU temp: 32-45 C
sytem temp: 28-34 C

It's also stable during stresstest programs and don't give errors even at 3.6Ghz, 1800Mhz FSB and memory on 1040 + overclocked timings. But if I start up a video even underclocked, Freeze within 30 mins.


HELP please!

Are you getting Blue Screens (Stop-Errors)? If so, follow the link in my signature labeled "How to Post Your BSOD."

Despite you testing with different hardware, my first-glance guess is that this is either a driver issue, or defective video card or RAM. After you answer my first question, we can get into that.

I don't get bluescreens, the machine just completely freeze with the sound from the video looping, "I have to go to go to go to go". When it happens sometimes the picture just freeze can't move mouse pointer, pull up taskmanager or anything. Other times it just turns my monitor off when it freeze. I have the same problem when I use my GF6800GT too,

I don't get any error logs (event viewer), well until today when I finally got the "your system has recovered from a serious error" but when I sent the error report it said "the error report submitted was corrupted, this is very rare bla bla bla"


However the computer has not crashed during videos for a couple of hours now, after I installed VLC and did a full registry clean with reg mechanic. 212 registry errors on a 14 day old installation. But I have many times before thought I had finally found the solution just for the 'puter to crash a little later.

The only hardware that has stayed the same is MB and cpu all other hardware has been changed for testing.

I could add that I have had some wierd sensor warnings, but I don't know if I can trust them. Like some channels get too high voltage according to pc-probe. But I think its a sensorproblem and not a voltage problem, coz once it claimed the cpu core got 4V. at that time the cpu started downclocking the multiplier first from 8x to 6x, then to 4x.
I turned off the computer and turned it back on and the voltage was correct again.
But it had to have been a sensor glitch coz with 4V into a 1.25V default core should melt it.

New development, yesterday it froze for the first time during a game, football manager 2008. So it's not a codec problem. It just freeze up easier during videoplayback.

Please post back with the results.

It reports newer drivers available for:

NVIDIA nForce 590/570/550 Serial ATA Controller
NVIDIA Network Bus Enumerator
NVIDIA nForce PCI System Management

All others are green. I have to be a member there to download those drivers, but I'll find them somewhere else, I have used all the latest drivers from Asus, am I supposed to go to Nvidia to download these newer drivers then?
