i have a dell inspiron 530 1.6ghz on vista home basic. I tried putting a nvidia geforce 8800 gts card in it. my computer boots up with all the icons looking 'olde worlde' and i can hardly read anything on the screen. Have i forgotten anything(i downloaded the driver for it from nvidia)
right click on your desktop. Select Properties. Then look in the tabs for settings. Then check to see if the resolution is what your looking for. Also, from the sound of it, you want to be running Color quality in "Highest (32 bit)"
