I have just bought a new graphics card as I found that 'Fifa 2005' wouldn't run at all on my old one as it was only 16mb. So I went for the gainward fx powerpack pro/660 128mb DDR. Fifa now runs, but very badly. The graphics look really bad with weird colours everywhere and writing missing from menus, etc. The sound is fine though so I'm assuming this is just a graphics problem. I have also found that 'hitman' which worked fine on my old card is not working now. The game starts with sound working fine but the screen is just black.
I have tried updating the drivers but that hasn't made any difference. I have direct x installed. My pc spec suggests that both games should run fine as I have checked with the minimum requirements on both games.
Unfortunately I'm not too wise when it comes to graphics and really need some help with this. Any help would be much appreciated.
