this just happens when i am in-game for example wow and cs. The deskop, windows etc, works fine. This is just when i try to play a game the screen do this.

2: Driver problem

After this unusually problem, i tried to reinstall the driver for the video card. I have a geforce 6600gt.
After i reinstalled and restarted the comp, the windows suddenly went to a different form. The theme went to windows 2000 and it was only 4 bit. I tried to change the resolution etc.. but it didnt worked.
So i checked which driver the video card used, and it was a very old one. it was like a 6.1xxx.. the one i had before i reinstalled was 8.8xx..

So when i was already in the device manager, i clicked the "roll back driver".
The comp restarted, and the windows etc works fine now. But its not the newest driver. The driver it went back to was a 7.8xxx.

Also, when i try to install the newest one. The windows get fucked up and i have to click the "roll back driver".

The comp works fine, its just that i can't install the newest driver and when i launch any games the screen shows a bad quality, unclear etc.

So please heeeelp !

If you are not experiencing any problems with the old drivers I don't see why you should have to update them? I know newest drivers might give extra performance but in some cases they just break the system.

That screenshot appears to be pointing towards overheating as your issue. It would not cause the OpenGL or color sampling issue, but it would cause the artifact issue. What you want to do for now is UNDERCLOCK your gpu. That will help with the artifacts. Now for the OpenGL and colors - you did it yourself. It is an issue that happens when people play with the drivers. So either find out what your drivers are supposed to be at default or uninstall all of the gpu drivers, run a registry cleaner, and hope that reinstalling the driver will fix it.
