Hi, im having problems with my new graphics card. Its a Winfast A6600 GT TDH CARD. Its installed with no installation errors and all the drivers are updated. It has weird glitches whilst playing. I play the Sims 2 and it has Flashes of the game appearing in the wrong places, bands of grass in the sky, the characters have 'holes in them'. It looks like theyre 'shattering' or 'disintregrating'. There are strips,bands,triangular shaped graphics out of place. It still plays but obviousley this is causing a problem in the look of the game. Anyone got any ideas?
