Hello everyone,
I have a Gigabyte GV-NX96T512HP [rev 2.0] (NVIDIA GeForce 9600 GT) graphics card.
Whenever I am playing a game (any game), after 10 seconds to 1 hour or later, this is what happens on my screen:
The textures corrupt:
This usually happens in games that use DirectX. I have not seen anything like this happen in games that use OpenGL before.
Occasionally, this problem can happen instantly without any screen freezes, but frequently; the screen freezes for about 5 seconds or longer. Then, the textures load on the wrong objects; simply, the textures corrupt.
This problem can be temporarily fixed by pressing the [CTRL]+[ALT]+[DELETE] keys or the [START] key on my keyboard to take me onto my desktop (It may take my desktop a few seconds to unfreeze and become interactive), I then go back into the game I am currently playing; it may take some time for the game to reappear. The textures should now appear on the correct objects, but these corruptions may happen again. They can happen more than once; if the textures in a game are already corrupted, the screen may flash or freeze for a short period of time and different textures appear. This can happen many times in a row. Every time after this problem happens, whenever I quit a game or exit a full screen program, my computer's performance decreases. The only way to get my computer to run with regular performance after the occurrence of these corruptions in games is to restart it.
Noise-like pixellation artefacts appear:
This problem happens in games that use DirectX too, but more often in games that use OpenGL (Trainz Railroad Simulator 2006 for example; which can use either DirectX or OpenGL).
What happens is that the screen freezes for about 5 seconds or longer (sometimes it does not). Then I see these artefacts all over my screen. These artefacts behave in a very similar manner to that of noise on a television screen. They will build up on my monitor to a certain point where most of them disappear then rebuild on the screen again, which happens repeatedly.
This can be fixed temporarily by restarting my computer safely, because simply minimizing or quitting the game will just not work.
Both of these problems can happen collaboratively until my computer itself freezes up to a point that it is impossible to go back to the desktop, terminate the game, log off/switch users, safely shut down or restart my computer. The only way out of this problem is to press the Reset switch on the front of my computer to re-boot into Windows.
These problems can also happen up to a point where I get a BSoD.
I am not sure about how I am going to fix these problems permanently without replacing the graphics card itself.
However, here is what I have done to try and fix/diagnose these problems. So far, these solutions have had no permanent effect on my graphics card:
Changing the graphics card's clock settings:
This solution almost worked, but did not work permanently.
In NVIDIA nTune, I changed the GPU clock from 450 MHz to 720 MHz and the Memory clock from 750 MHz to 1008 MHz.
I have also tried other clock settings, but these problems still kept happening.
Using an older graphics card:Re-installing NVIDIA GeForce drivers:
This solution did not really seem to do anything.
Changing the PCI Express bus clock speed:
This solution did not work either.
Using a lower screen resolution:
This solution did not work either.
Plugging my monitor into the second DVI port (marked with a blue colour):
I initially thought that this solution worked; but really, it did not.
Uncovering the NVIDIA SLI contacts on the graphics card:
This solution did not work either.
Using only one RAM module:
This solution did not work either.
Using a more powerful Power Supply:
I used to use a 400 Watt PSU.
I changed it for a 500 Watt one, but doing this didn't make any difference.
Playing a newer, very recent game with this card:
These problems still happen.
Testing this card in a different computer or in a computer with a different chipset or motherboard:
Successfully, There were no texture corruptions or noise-like pixellation artefacts in 3DMark06, even with my DDR2 SDRAM modules in a different system.
I think it seems like my motherboard may have something to do with these problems.
I even wrote a letter to Gigabyte about this:
Here is their reply:
Does anyone know what else (anything else other than what I have mentioned) might be causing these problems?
Are there any other solutions to this problem that I have not thought of yet?
I would appreciate all of your help. Thank you.

Hello there,
Whenever I am playing games (many games), the textures corrupt after a few minutes of gameplay, and less frequently, a noise-like heavy pixellation occurs (See attached screen capture).
I have had this card for at least 3 months now, and it has been happening with varying severity over that period.
The games I play are:
- Prince of Persia: The Sands of Time
- DRIV3R
- Microsoft Train Simulator
- Microsoft Flight Simulator X
All other applications in Windows XP are fine, it is only the games that have this problem.
This card passes all DirectX tests. Both versions 9.0c and 10.0 have the same problem.
I also provided information from my NVIDIA Control Panel, which may be useful (Attached screenshots).
What should I do to correct this problem?
