Hi there,
I managed to convince a friend to give me his old card (6600GT) when he upgraded to a newer one.
After installing latest drivers etc, I began playing some games, worked fine, decent improvement in speed and quality over last card.
However, when running world of warcraft, after a while playing, the card begins to have problems (see below), I thought it could be the heat due to it only having problems after a certain amount of time, however, after installing a total of 3 new fans and a temperature monitor, it still plays up dispite adequate cooling from external fans plus its own.
Drivers are up to date, I've a 550 power supply.
2.8ghz x86 genuine intel processor
1gb DDR Ram
OS: XP SP2
Attached is a screenshot of the game when its having its problems, I'm sure I don't need to say what is wrong with teh pic.
Thanks for all replies in Advance

Your best bet it updating your shipset drivers (very very easy)
