3D video problems

I'm been seeing some anomalies when I'm playing 3d games on my GeForce 4200. After playing Medal of Honor or UT2003 for a few minutes, I'm having some sort of color problem where a bunch of textures on the screen change colors. These textures take on some sort of rainbow effect that I've never seen.

I've also noticed that the screen kind of flickers at random places on the screen itself. It doesn't necessarily happen to the whole screen and only every few seconds.

I attempted to re-install the drivers with no luck. I re-installed WinXp and still no luck.

I can't think of anything that changed, except for adding additional memory to my computer. I'm not having any problems with 2D graphics at all.

Does anyone have any advice? or know what this problem is?

Thanks,
Josh
 
Could be the new memory. Run memtest86, you can find it on google. which version of directx are you using and which nvidia drivers are you using?
 
Will,

Thanks for the response.

I did run memtest for a few hours and it did give me two errors in the 400-500MB range which I am assuming is the second DIMM I bought (I have a total of 512MB). I stopped the test, removed the DIMM and tried a game again. I have yet to see any of the graphics anomalies I saw previously, so I am assuming it is the 2nd DIMM I bought.

It is a different manufacture than my other DIMM (1st - Samsung, 2nd - PNY) but I've never really had a problem mixing memory manufacturers in the past (as long as the memory type was the same). These happen to both be 256MB DDR 2700 DIMMS. Do you think that would make a difference?

The tech I talked to on the phone for the video card company (EVGA) said it sounded like bad memory on the card, but I'm seriously thinking its the system memory. I wonder if they would have similiar symptoms?

Anway, I think I'm going to return the memory first because it should cost me nothing to exchange it (EVGA wants to charge me around $40 to RMA a video card that is less than a year old).

Thanks again for the advice,

Josh
