i have a dell inspiron 9100 2.8ghz xp pro sp3 1 gig ram and a 9800 256 video card. I tryed to update the drivers by using the ati drivers but im not sure im using the right one. I was using the ati 9800 driver and when i get it installed and run the program it just finished and doesn't say anything but completed and there is no windows comparability error. I reboot and still have crappy graphics. im not good with computers so if someone could help me that would be great.
