8800GTS graphics bug

[Emo]

Hi everybody! I am writing this message because I meet a big problem with my 8800GTS.

When I launch a game, it runs pretty well for 1 minute or two, then, I have a bug display. The game continued to run behind May I have a screen of any color. I meet this difficulty, especially with BioShock.
I formatted my pc completely reinstall the latest drivers, and nothing changes. Also this bug. I know what to do ....
If you have any ideas that would be nice!

Here is my config:
Microsoft XP SP3
Intel quad core 2 GHz CPU Q6600@2.40
2 GB of RAM DDR2
football Gigabyte GA P35 DS3
and my Nvidia 8800GTS 512 MB ..

Thank you again!

Your config is too good, but after the screen I see a bump texture mapping, nothing more.
Your problem is the SP3 it raises hundreds of bugs for games and hardware issues, try uninstalling SP3 so.

As you overclock your graphics card or something else, it causes sometimes jerks in games

No, I did not overclocked ...

I do not know, it happens in all games or only in specific games?

I have (almost) the same bugs in Half-Life 2 when overclock my card so when it heats too, may be that your card heater too.
