3D Corruption

I'm having trouble with corrupted 3D graphics in games. The 2D seems to all appear fine, however, the textures in certain spots of models are completely transparent. They seem to flash in and out rapidly. Some games are worse than others. Company of Heroes has minimal corruption, while Neverwinter Nights 2 is practically unplayable.

Here is an example:



I would really like to upgrade to a PCI Express mobo and an SLI video card, but I'm not quite ready to make that kind of investment. I'm hoping that this is a graphics card issue and not something else. I would like to replace the graphics card (hopefully fixing the corruption) for now until I am ready to build a new PC. Any comments/suggestions?
 
ATI Radeon 9600

Running at about 50 Deg C although I don't normally monitor it.

I've been having this trouble for a while, just haven't bothered to fix it as most games seem to run okay. The first time I had trouble with it was the F.E.A.R. demo.
 
go to ur desktop, right click, properties, settings, advanced, troubleshoot, and disable write combining. Then tell me if it works :)
 
No success

I tried disabling write combining. I also tried uninstalling my current drivers, rebooting, and installing the most current drivers from ATI. I'm not paying for driver cleaner given the slim chance it will even solve anything.

I should mention that I was having this same problem before a complete HD format and windows reinstall. That leads me to believe it is hardware related. It would be nice to know if it is the graphics card that is causing the problem and not something else.

I tried sending an e-mail to ATI's tech support a while ago, but I had difficulty describing the problem and since it was the FEAR demo I was having problems with I thought it might just be the game.

Thanks for the replies so far.
 
Can you pull the graphics card out of your PC and maybe give it a bit of a clean with an air duster (or vacuum cleaner). Also check that when your PC is turned on the fan on the card is spinning.

I managed to totally kill an nvidia card a while back after not realising that the fan on it had died.
 
That is some serious corruption. Remember my old Voodoo card doing that a while back. Turned out the AGP settings in the BIOS were wrong.

Although not sure about ATI cards myself. Do they have some sort of texture compression that could be corrupting them?
 
Have you tried to maybe underclock your video card i get that stuff when i overclock my ram on my 6800 to much maybe your ram is dieing try to run it lower then stock.
 
Yeah, running too quick, getting too hot. Some boards can have a lower tolerance of heat than average.

If u were nVidia I`d also add that too new a driverset has done this for me - but u is ATi, can`t comment if u can get the same with these.

All else, try re-doing Dx, uninstall u`r drivers - doing a driver clean - then put em back in, possibly through safe mode.

Bah.. lots of opportunities.
 
Update: New Video Card

Okay, so I bought a new video card. Unfortunately I'm having the same issues. I uninstalled the display adapter, then the catalyst drivers, then the ATI uninstall utility using add/remove programs. I shut down the computer, switched cards, and powered back up. From there I installed the drivers and software for the ATI Radeon X1640PRO. I tried tried turning on AGP Fast Write, USWC, and increasing the Graphics Aperture Size in the BIOS. I will try installing the latest catalyst drivers, but I doubt it will help anything.

I'm thinking it's either the processor, the MB, or the RAM now. I'm also thinking I might be better off building a new computer since this one is fairly outdated. Any other suggestions?
 
Now if this was me, apart from being pretty pished at this, I`d start trying older drivers, the ones that came on the cds with the gfx card should suffice.

Anything just to get a working base.
 
Any chance you can get your hands on a spare nVidia card to try it out?

If you get probs then, it should tell you there's a problem with the mobo. Try giving the chipset drivers an update if you haven't done so already.

I dunno how ATI run their driver support but I know that nVidia have a "Driver Archive" where all past drivers are stored, ready for D/L.
