I have tried to find info on the forum for this but it always seems to be for different graphics cards etc so am unsure of applicability to me. If already covered my apologies. I'm unable to run the gold edition on my new HP Pavillion dv9428nr, nVIDIA GeForce Go 6150 graphics card with the most recent driver ver 7.15.10.9815A build date 2007-05-10 (though in device manager it shows as ver 7.15.10.9815 build date 2/27/2007), AMD Turion 64x2, and Vista Home Premium (2006). I have had a lot of difficulties with this unit, google sketchup crashes for instance. It goes through the opening screens but when it actually gets to the 1st game screen it flickers oddly and doesn't do anything. If I "alt+tab" back to the desktop and then go bck to Gal Civ the screen is featureless, no images at all. In Task Manager the program still shows as running. I have been told both that it is a video driver issue but that because the graphic card was modified for the HP dv9428nr that updates must come from HP not nVidia and I have gotten the same driver file through 3 different searches. I have also been told it's an incompatibility with Vista. Have all latest updates and still no joy. Can anyone point me in the right direction?
