Strange Rendering Issue *Screenshot*

[brohken]

So recently I started seeing some really strange rendering issues with my CS during gameplay. The text overlays also look really funny sometimes and I have to minimize/maximize CS:S to get it to look right again.

I'm running:
Windows XP SP2
Latest Drivers on Everything I can think of.
M-Audio 5.1 Sound Card
GeForce 7600 GT
Nvidia Driver Version: 6.14.11.7519

Here's a screenshot I was able to pull, but this doesn't show the text issue I was seeing as well.

Sometimes floors turn completely white and ceilings also change colors. This happens on most maps and it happens on many different servers.

Thanks for your help guys!

The usual cause of artifacting and glitching like this is an overheating/broken graphics card. Check that the fan is running properly, and it's not getting too hot.

here's what happens when I run the CS:S stress test. it idles at around 53ºC and goes to 62ºC at the hottest
